                 Workshop on Measurements and Standards for Biofuels:
            Enabling a Transition from Petroleum as a Vehicular Energy Source
                                   Rio de Janeiro, Brazil
                                   September 14-15, 2006

Background: Following up on the agreements reached at the US-Brazil Commercial Dialogue
between Secretary Gutierrez and Minister Furlan held in Brazil on June 6, 2006, and the US-
Brazil Ministerial Joint Commission Meeting held in Washington DC on July 21, 2006, the two
sides agreed to explore cooperation in Metrology and Standards for Biofuels.

As a first step, a workshop on “Measurements and Standards for Biofuels: Enabling a Transition
from Petroleum as a Vehicular Energy Source”, organized by NIST and INMETRO (National
Institute of Metrology, Standardization and Industrial Quality of Brazil), was held on September
14-15, 2006 in Rio de Janeiro. The participants represented government and private sector
organizations from Brazil and the U.S.

Ideas Discussed: The workshop focused on measurement and standards issues with regard to the
production, distribution, and quality (calorific value, anti-corrosiveness etc.) of biofuels. The
Brazilians shared experiences and raised measurement and standards issues that pose technical
challenges to the shift from petroleum to biofuels. Technical areas for NIST-INMETRO
cooperation identified at the workshop included:

      1) Review of inconsistencies between ABTM (Brazilian), ASTM (US), EN (European)
         and ISO (international) documentary standards, both in terms of specifications and
         measurement conditions;

      2) Definition of relevant measurands for determining fuel quality and their impact on
         materials performance;

      3) Development of new performance based measurement methods;

      4) Development of new Certified Reference Materials (CRMs) to assure the accuracy of
         measurements used to characterize biofuels;

Action Plan: The following areas were highlighted as topics for future discussion:

      −   Review of specifications for biofuels as commodity products;

      −   Identification of new Reference Methods and CRMs to improve measurement

      −   Critical evaluation of field methods for assessing fuel quality at the production site;

      − Review of available thermophysical property data relevant to processing and
          characterization of biofuels;

      −   Impact of biofuels on corrosion properties of materials.
