1.0   INTRODUCTION

      This Joint Test Protocol (JTP) contains the critical performance requirements and
      tests necessary to evaluate the performance of degradation preventive materials to
      be used for degradation mitigation on various types of textiles. The potential
      degradation preventive materials will hereafter be referred to as “candidates.”
      The JTP provides a standard set of tests and test conditions that the
      manufacturers, the United States (U.S.) military, and third-party testing
      organizations may use to fairly gauge how the candidate compares to existing
      degradation preventive materials. With the test results presented in a Joint Test
      Report (JTR), the manufacture and military can make an informed decision with
      regard to subjecting the candidate to qualification testing for inclusion on the
      Qualified Products List (QPL).

1.1   Scope

      This JTP establishes the degradation resistance performance requirements that
      must be met for a candidate to be considered for use on textiles. Other properties
      of potential candidates will also be considered (see Feasibility Study discussion in
      the Section 1.2). However, the evaluation of these properties is specific to the
      application, and will be considered acceptable based only upon equal or improved
      performance when compared to the degradation resistance product currently being
      used.

      It must be emphasized that this JTP docume nt is not a process, material, or
      product specification, nor is it intended to address ongoing quality issues.
      The testing outlined in this document confirms the technical capabilities of the
      candidate for the particular application with respect to material degradation, and
      qualifies the candidate for consideration for military use by the relevant armed
      services’ Corrosion Office invoking the JTP (e.g., the Army Corrosion Manager)
      or the relevant Program Manager (both hereafter referred to as “the invoking
      authority”). It should also be emphasized that successful completion of the
      procedures outline in the JTP does not obligate the U.S. Army or any other
      Department of Defense (DoD) organization to procure or use the cand idate.
      Finally, it should be noted that the vendor offering a candidate is responsible for
      funding the tests described herein.

1.2   Execution

      This document is organized in such a manner as to aid the user during the material
      degradation study planning stage, throughout the testing activity and during the
      reporting and interpretation phases. This section describes the use of this
      document by outlining the steps that will guide the user through the process of
      extracting and utilizing material degradation data. Section 2.0 describes a logical
      flow to the process of evaluating the results of the material degradation
      Performance Tests and comparing the properties of the candidate with established


                                                     1
                    Joint Test Protocol Evaluation of Degradation Protection for Textiles
comparative acceptance criteria necessary to qualify the candidate for potential
military use. Section 2.0 also provides a test flow diagram and an example of a
situation in which the JTP could be used. Section 3.0 discusses application
scenarios, the test method matrix, and methodology. Section 4.0 describes test
requirements (acceptance criteria) and procedures. Section 5.0 discusses failure
analysis. Finally, Section 6.0 provides a list of reference documents that were
utilized in the preparation of this JTP.

The material degradation performance of candidates to be evaluated using this
JTP will be determined through a series of evaluation tests. These evaluations
have been derived from engineering, performance, and operational impact
(supportability) standards defined by a consensus of government and industry
participants. The tests in this document are based upon recognized commercial
and military test standards that are currently in use by established test facilities.
After exposing the materials to the various environmental conditions, they will be
subjected to standardized mechanical tests to quantify the degradation in
performance of the textile materials. If the JTP test method conflicts with the
reference standard on which it is based, the JTP test method will take
precedence.

Prior to conducting the required Performance Tests, a candidate must undergo a
preliminary Feasibility Study, in which the following considerations shall be
addressed:

      The candidate must demonstrate compatibility with the existing system,
       i.e., it must not introduce permanent adverse effects on the functionality of
       the other components of the system into which it will be incorporated.
      The candidate must conform to current military environmental regulations
       and concerns, such as atmospheric and groundwater impact, volatile
       organic compound (VOC) content, waste disposal, etc.
      Procurement of the candidate must be compatible with standard military
       business procedures. Considerations include, but are not limited to:
       distribution status (domestic/offshore); product cost analysis; and vendor
       capability, reputation, and reliability.

The Feasibility Study shall be conducted prior to the execution of the test
program contained in this JTP. The business issues assessment shall be
conducted again at the completion of the JTP testing if business issues have
changed as a result of product and/or financial changes. The actual
implementation of the Feasibility Study shall be conducted through the invoking
authority, and is outside the scope of this JTP.

The tests outlined in this JTP are organized into two general areas, Performance
and Special Testing. Performance Testing involves those tests required for
evaluating any candidate material. Special Testing includes those tests identified
by some (but not all) stakeholders for evaluating material degradation in special


                                               2
              Joint Test Protocol Evaluation of Degradation Protection for Textiles
      applications. The candidate must meet both Performance and applicable Special
      Testing requirements to be considered for special applications.

      A JTR will document the testing conducted on each candidate in accordance with
      this JTP. This JTR will provide a record of test specifics, such as candidate test
      specimen preparation, any additional preparation processing, test equipment
      model and calibration details, laboratory environmental conditions, and test
      results. Whenever possible the JTR will conform to the reporting guidelines
      specified in the industrial measurement methods and standards, such as American
      Society for Testing and Materials (ASTM) or American Association of Textile
      Chemists and Colorists (AATCC). If planned execution of the tests varies from
      that described in this JTP, test procedure modifications must be approved by the
      invoking authority in advance and documented in the JTR. If the JTR does not
      contain the candidate vendor’s proprietary information, it may be used as a
      reference for future related material degradation endeavors by other DoD and
      commercial users, and thus could be used to minimize duplication of efforts used
      in evaluating other related candidates.

1.3   Document Maintenance

      Annual updates and general maintenance of this document will be the
      responsibility of a committee chaired by the Army Corrosion Office or designee.
      The document will be reviewed and updated on an annual basis with changes
      being noted on the “JTP Revisions History” page. If no changes have been made,
      the entry “no revisions have been made for the year 20xy” will be entered where
      appropriate. This document is considered to be obsolete if the latest entry on the
      JTP Revisions History is more than two years old. In that case, contact the Army
      Corrosion Office or designee for the most recent revisions before conducting
      testing in accordance with this JTP.

2.0   JTP DOCUMENT GUIDE

      This section of the JTP facilitates the use of this document by providing a logical
      implementation flow process, as well as an example of a JTP evaluation for a
      potential candidate. Use of this document for qualifying a candidate for potential
      use utilizing the procedures in the Performance and Special Testing sections is
      described.

2.1   Overvie w

      As noted in the Introduction, the tests in this JTP are organized into two general
      areas, Performance and Special Testing, and their application is outlined in the
      flow diagram depicted in Figure 1.

      As shown in Figure 1, the evaluation process begins with the Feasibility Stud y. If
      the candidate conforms to current military environmental regulations, and the
      procurement of the candidate would be compatible with standard military
      business procedures, the subsequent testing that is required can be determined
      from the Test Method Matrix (Table 1).

      A failure analysis can be performed on any test specimen that fails a specific
      Performance or Special Test to determine the cause of failure (see Section 5.0).
      Failure in any test does not necessarily disqualify a candidate for use in all
      possible applications; however, issuing a waiver to use a candidate that has failed
      a Performance or Special Test is at the discretion of the invoking authority, and is
      outside the scope of this document. Following completion of testing and/or
      failure analysis, the JTR is to be forwarded to the vendor for further transmittal to
      the invoking authority for review.

      Note that while the invoking authority is referenced throughout the document for
      information reviewing and certain decision making, the independent test lab(s)
      conducting the test shall not directly deliver results to the invoking authority
      (unless requested to do so by the candidate’s vendor, or if the test lab is the third
      party test lab described under Failure Analysis, Section 5.0). Instead,
      communication to the invoking authority shall first go through the vendor. This is
      intended to allow a vendor to test and, if necessary, re-engineer a product until it
      is satisfactory, with a limit of three cycles as described below.

      Figure 1 illustrates the process flow for conducting the Performance Tests (and, if
      invoked, the Special Tests) and reporting the information. Note that in Figure 1
      there are two potential “infinite loops” that may occur due to either Performance
      or Special Testing failures other than those related to product failure. To avoid
      this, if the candidate fails either Performance or Special Test a third time, do not
      repeat the testing. Rather, terminate the testing cycle and forward the JTR to the
      vendor for re-engineering decision.

2.2   Implementation Example

      The following example is provided to demonstrate how this JTP can be used for
      Performance and Special Testing situations.

      Example #1

      SITUATION : A vendor proposes a replacement antifungal liquid to be applied to
      Army tents. The invoking authority also designates that a special test is needed to
      address an additional concern.

      EVALUATION:
        1. The JTP directs the user to the JTP Test Flow diagram (Figure 1). The
           Feasibility Study is conducted and initial assessments regarding
           compatibility, environmental concerns, and overall business risk are
           satisfied.
        2. The Feasibility Study is found to be positive and the relevant Performance
           and Special Tests are conducted.
        3. The invoking authority compares the data from the control and candidate
           and determines that the candidate material provides better degradation
           protection for the Army tents.

      RESULT: The JTP establishes the requirements for consideration and provides
      the methodology for documenting the relative degradation performance of the
      candidate material compared to the control. The invoking authority utilizes the
      test data to make a determination as to the acceptability of the candidate material
      for the particular application.

3.0   APPLICATION SCENARIOS

3.1   Guidelines

      This section establishes the guidelines for testing the degradation performance of
      a potential candidate material to be used in a new or existing application.

      Table 1 establishes the test methodology to be applied to a potential candidate for
      Performance and Special Test procedures. The table lists the test methods to be
      employed as well as the location of the test procedure within the JTP document.

3.2   Methodology

      Performance and designated Special Tests shall be conducted on specimens of
      both the control material and the candidate. In the case of the control, the
      specimens could be extracted from the existing product or fabricated as a new
      specimen.

      The guidelines for testing candidates under this JTP are as follows:

         1. Supply the appropriate control and candidate material specimens for
            testing. (Reference each appropriate test procedure for determining the
            number of specimens and its size).
         2. Obtain approval from the invoking authority for test procedure
            modifications, if applicable.
         3. Perform applicable testing and obtain and analyze the test results.
         4. Submit JTR to the vendor for transmittal to the invoking authority for
            review.

                    Joint Test Protocol Evaluation of Degradation Protection for Textiles
4.0   TESTING REQUIREMENTS

      The stakeholders and contributors have established the requirements necessary to
      evaluate any textiles degradation prevention material for use by the military.
      Tests to satisfy qualification requirements have been developed with detailed
      procedures, methodologies, and acceptance criteria to qualify the candidates.

      Section 4.1 outlines the Performance Testing requirements. Special Test methods
      are identified in Section 4.2. Special Testing includes those tests for evaluating
      degradation prevention material in special applications and are to be applied when
      requested by the invoking authority. To be considered for possible military use
      the candidate must have test results that equal or exceed those for the control
      specimens.

      In instances where the JTP test method differs from the reference standard
      on which it is based, the JTP test method will take precedence.

      As noted in Section 1.2, if planned execution of the tests varies from that
      described in this JTP, test procedure modifications must be approved by the
      invoking authority in advance and documented in the JTR. This option allows
      (fully documented) variation from the stated requirements in the following
      sections. An example might be a candidate material that is too fragile to survive
      the specified 1680 hours of ultraviolet (UV) and moisture exposure (per Section
      4.3.3) and is thus only tested at 168 hours of exposure.

      All testing shall be performed at the vendor’s expense by a government or
      independent testing laboratory that has been agreed upon by the invoking
      authority. The independent laboratory must either be accredited by a recognized
      governing body (such as the American Association for Laboratory Accreditation
      (A2LA) or the National Voluntary Laboratory Accreditation Program (NVLAP),
      or be an ISO 9001 certified company having its own testing laboratory.
      Testimonials shall be used for informational purposes only, and are not to be
      used in lieu of tests require d under this JTP. If requested by the vendor, the
      results from previous studies on the candidate material by an outside laboratory
      can be incorporated into the JTR but only at the concurrence of the invoking
      authority.

      The tests described in this JTP may involve the use of ha zardous materials,
      operations, and/or equipment. This JTP does not address all of the safety issues
      associated with their use. It is the responsibility of each user of this JTP to
      establish appropriate safety and health practices, and to determine the
      applicability of regulatory limitations, prior to the use of such materials,
      operations, and/or equipment.

      It should be noted that the default acceptance criteria given in Sections 4.3 and 4.4
      are based on the assumption that the new candidate should deliver better

      performance in all aspects than the baseline material. However, in certain
      circumstances, it may be acceptable to the Invoking Authority that the candidate
      have lower performance than the original (for example, in cases where the
      primary interest is in reducing or eliminating heavy metals from an anti- fungal
      spray). In such cases, the Invoking Authority may set out new acceptance criteria,
      which shall be noted in the Joint Test Report.

4.3.1   Antifungal Resistance, Soil Burial

4.3.1.1 Scope

        This test method, Antifungal Activity, Assessment on Textile Materials: Mildew
        and Rot Resistance of Textile Materials – Soil Burial (AATCC Test Method 30,
        Test I), describes the procedure for determining the susceptibility of textile
        materials to mildew and rot and to evaluate the efficacy of fungicides on textile
        materials after soil burial. Resistance of the test material to degradation is
        compared to that of a comparison standard. This test method should be used for
        those textiles that will come into direct contact with soil, such as, sandbags,
        tarpaulins, tents, etc.

        For this test method the following definitions apply:

        Mildew resistance: Resistance to development of unsightly fungal growths and
        accompanying unpleasant, musty odors.

        Rot resistance: Resistance to deterioration of a textile material as a result of
        fungal growth in or on it. Measuring loss in tensile strength assesses such
        deterioration.

4.3.5   Wate r Resistance: Rain Test

4.3.5.1 Scope

        This test method, based on AATCC Test Method 35, is applicable to any textile
        fabric that may or may not have been given a water-resistant or water-repellent
        finish. It measures the resistance to the penetration of water by impact and thus
        can be used to predict the probable rain penetration resistance of fabrics.

4.3.5.2 Equipment

        AATCC Rain Tester. The AATCC rain tester is available from AATCC and must
        conform to the requirements shown in Figures 1-3 of AATCC Test Method 35.
        Conditioning Chamber. A chamber capable of maintaining an environment of 65
        + 2% RH and 21 + 1C (70 + 2F).
        Balance. A balance capable of weighing to the nearest 0.1 g.

4.3.5.3 Reagents

        Distilled Water. Conforming to Type IV water in the latest version of ASTM
        D1193.

4.3.5.4 Procedure

        Test Specimens. The test specimens shall be 20 x 20 cm (0.8 x 0.8 in.). A
        minimum of nine (9) specimens shall be coated with each candidate and nine (9)
        shall be coated with the currently used coating (control) per each manufacturer’s
        instructions. If the current application is to use uncoated textile, then the control
        test specimens shall be uncoated.
        Preparation. Condition the test specimens in an environment of 65 + 2% RH and
        21 + 1C (70 + 2F) for at least 4 hours before testing. Weigh a 15.2 x 15.2 cm
        (0.6 x 0.6 in.) sheet of AATCC white textile blotting paper to the nearest 0.1 g.
        Test Procedure. Clamp the textile test specimen and white blotting paper in the
        vertical support frame of the rain tester. Check that the spray nozzle is at a
        distance of 30.5 cm (12 in.) from the test specimen and that the test specimen is
        centrally located in the spray pattern. A horizontal water spray at 27 + 1C (81 +
        2F) should be directed against the test specimen for 5 minutes. At the end of the


                                                      16
                      Joint Test Protocol Evaluation of Degradation Protection for Textiles
        spray period, remove the blotter quickly and reweigh to the nearest 0.1 g. In order
        to obtain an overall picture of the penetration resistance of a textile, the average
        penetration with different pressure heads on the nozzle should be obtained. The
        following columns of water should be used: 0.9, 1.5 and 2.4 m (3, 5 and 8 ft.)
        above the nozzle. See Section 11.1 of AATCC Test Method 35 for a means of
        producing the various heads of water.
        Test Results. Photograph the test specimens and blotter paper before placing
        them in the support frame and after completion of the spray period. Reweigh the
        blotter paper to the nearest 0.1 g.
        Report. Report the material information, water spray temperature, blotter paper
        weights (before and after spray), average blotter paper weight, duration of spray
        period and water head. Individual determinations or average values of over 5 g
        may simply be report to > 5 g. Include the photographs taken to document the
        blotter’s conditions after exposure.

4.4     Test Descriptions – Special Tests

4.4.1   Wate r Repellency: Spray Test

4.4.1.1 Scope

        This test method, AATCC Test Method 22 (Water Repellency, Spray Test) is
        applicable to any textile fabric and it measures the resistance of fabrics to wetting
        by water. It is especially suitable for measuring the water-repellent efficacy of
        finishes applied to fabrics. It is not intended for use in predicting the probable
        rain penetration resistance of fabrics, as that is the scope of AATCC Test Method
        35.

4.4.1.1 Equipment

        AATCC Spray Tester. The AATCC spray tester is available from AATCC and
        must conform to the requirements shown in Figures 2, 2A and 3 of AATCC Test
        Method 22.

        Conditioning Chamber. A chamber capable of maintaining an environment of 65
        + 2% RH and 21 + 1C (70 + 2F).

4.4.1.2 Reagents

        Distilled Water. Conforming to Type IV water in the latest version of ASTM
        D1193.

4.4.1.3 Procedure

        Test Specimens. A minimum of three (3) specimens shall be coated with each
        candidate and three (3) shall be coated with the currently used coating (control)


                                                      17
                      Joint Test Protocol Evaluation of Degradation Protection for Textiles
        per each manufacturer’s instructions. If the current application uses uncoated
        textile, then the control test specimens shall be uncoated. Test specimens must be
        180 x 180 mm (7 x 7 in.) and should be conditioned at 65 + 2% RH and 21 + 1C
        (70 + 2F) for a minimum of 4 hours prior to testing.
        Preparation. Securely fasten the test specimens in the 152 mm (6 in.) metal
        hoops. Place the hoop on the test stand with the fabric in such a position that the
        center of the spray pattern coincides with the center of the hoop.
        Test Procedure. Pour 250 mL of distilled water at 27 + 1C (80 + 2F) into the
        funnel and allow it to spray onto the test specimen in 25-30 seconds. Do not
        touch the funnel with the water beaker, as movement of the funnel will alter the
        spray disposition on the specimen. After the spraying the fabric, take the hoop by
        one edge and tap the opposite edge once against a solid object, with the fabric
        facing the object, then rotate the hoop 180 and tap once more on the point
        previously held. Repeat the above steps for all test specimens.
        Test Results. Photograph the test specimens before and after spraying. Compare
        the wet or spotted pattern on the fabric with the rating chart shown in Figure 1 of
        AATCC Test Method 22. Rate the side of the fabric impacted by the water
        corresponding to the nearest standard in the rating chart. Intermediate ratings can
        be used for ratings of 50 or higher. If the fabric is a loosely woven or porous
        fabric, disregard any passage of water through the openings of the fabric.
        Report. Report the material information and the individual rating results for each
        test specimen. Do not average the results. Include the photographs taken to
        document the test specimens’ conditions after spraying.

      firmly in its holder while subjected to the flame test.
      Conditioning Chamber. A chamber capable of maintaining an environment of 65
      + 2% RH and 21 + 1C (70 + 2F).

4.4.2.3 Reagents

      Methane gas that is 99%+ pure.

4.4.2.4 Procedure

      Test Specimens. The test specimens shall be 76 x 305 mm (3 x 12 in.). A
      minimum of five (5) specimens shall be coated with each candidate and five (5)
      shall be coated with the currently used coating (control) per each manufacturer’s
      instructions. If the current application is to use uncoated textile, then the control
      test specimens shall be uncoated.
      Preparation. Condition all test specimens under conditions of 65 + 2 % RH and
      21 + 1C (70 + 2F) until changes in weight in successive weighings made at
      intervals of one hour are no greater than 0.25 percent.
      Test Procedure. Set the test cabinet in a laboratory fume hood with precautions to
      minimize any drafts through the hood while testing. Adjust the gas pressure to
      17.2 + 1.7 kPa (2.5 + 0.25 pounds per square inch). Ignite and adjust the pilot
      flame approximately 3 mm (1/8 in.) in height. The burner flame shall be adjusted
      to give a flame height of 38 mm (1.5 in.) with the solenoid fully open and the air
      supply to the burner shut off. It is important that the flame height be adjusted to
      the level of the metal prong. Clamp the specimen in its holder such that the entire
      length of the specimen is exposed. The specimen shall be positioned in the test
      cabinet such that the middle of the lower edge of the specimen is centered 19 mm
      (3/4 in.) above the burner and level with the bottom metal prong. To start the test,
      open the solenoid and let the test run for a period of 12 seconds.
      Test Results. Photograph the test specimens before and after the vertical burn
      test. Determine the afterflame time by measuring the time to the nearest 0.2
      seconds that the specimen continues to flame after the 12-second period.
      Determine the afterglow time by measuring the time to the nearest 0.2 seconds
      that the specimen continues to glow after it has ceased to flame. After the test
      specimens have cooled, measure the char length per the procedure specified in
      5903.1.
      Report. Report the individual material information, the individual and average
      afterflame, afterglow and char measurements. Include the photographs to
      document the specimens’ condition after the vertical flame test.

5.0   FAILURE ANALYSIS

      To be considered for use as replacements for conventionally used materials,
      candidates must pass all tests. The failure of any Performance or Special Test
      shall be documented. At the candidate vendor’s request and expense, a Failure
      Analysis procedure can be undertaken to determine the failure mechanisms. Such
      failure analysis can be a useful vendor option. However, after failing any of the
      Performance or Special Tests for the third time, further iterations of that test are
      not permitted. Instead, the JTP process shall be ended and the results noted in the
      JTR. The JTR shall then be forwarded to the vendor for transmittal to the
      invoking authority for review.

      In the event of any testing-related dispute between vendor and tester, such as
      causes of premature failure, a third-party testing lab will be mutually agreed upon
      as a credible testing source by the invoking authority. This Product Failure
      Laboratory (PFL) must have no pre-existing connections to either the vendor of
      the candidate or the original laboratory that conducted the testing. The process
      flow is illustrated in Figure 1, which appears in Section 2.0, JTP Document
      Guide.

      Marginal test results must be either overcome by retesting or documented before
      rejecting/failing the candidate. Failure in any test does not necessarily disqualify
      a candidate material for use in all possible applications.

      The initial JTR and all related JTRs (specifically those documenting failure
      analyses) should be forwarded to the vendor for transmittal to the invoking
      authority.
