Important Instructions

This guidebook contains information on hazardous chemicals
and recommendations for the selection of chemical protective
clothing materials based on published and unpublished scien-
tific test data. NO attempt has been made to ensure either the
accuracy or precision of these compiled data. The guide also
does not take into consideration the intended use or physical
demands (resistance to tear, puncture resistance, etc.) of the
chemical protective clothing. These factors are critical in the
selection process. ALL selections based on this guide MUST be
reviewed by a person competent in the selection of chemical
protective clothing, such as a certified industrial hygienist or a
certified safety professional with training in this area.

Committee F23 on Protective Clothing

Staff Manager: Stephen Mawn smawn@astm.org (610) 832-9726

The American Society for Testing and Materials, ASTM Committee F23 on Protective Clothing was formed in 1977. F23 meets twice a
year. Currently has jurisdiction of more than 35 standards, published in the Annual Book of ASTM Standards, Vol. 11.03. These stan-
dards have and continue to play a preeminent role in the protective clothing industry and address issues relating to particulates, physical,
chemical, biological, end items, human factors, use, and flame and thermal.
