1.1 Materials used on an industry-wide basis as reference materials are vitally important to conduct product, specification, and development testing in the rubber and carbon black industry. This practice describes the steps necessary to ensure that any candidate material, that has a perceived need, can become a Reference Material. The practice sets forth the recommendations on the preparation steps for these materials; on the testing that shall be conducted to permit acceptance of any candidate material and on how the documentation needed for the acceptance shall be recorded for future use and review.

1.2 This practice shall be administered by ASTM Committee D11 in consultation on all matters with Committee D24.
