Additional information

1. Scope

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.

Important sections of this practice are as follows:

	Section
Significance and Use of the Standard	3
Preparation of Industry Reference Materials	4
Overview of Industry Reference Material Testing	5
Chemical and Physical Specifications for IRM	6
Reference Material Documentation	7
Assignment and Tabulation of Reference Material Numbers	8
Typical Reference Material Use	9
Recommended Package Size for IRM	Annex A1
Recommended Sampling Plans for Homogeneity Testing of an IRM	Annex A2
Test Plan and Analysis for Homogeneity of an IRM	Annex A3
Test Plan and Analysis to Evaluate an Accepted Reference Value	Annex A4
Statistical Model(s) for IRM Testing	Annex A5
Example of Annex Calculations for a Typical IRM	Appendix X1
Two-Way Analysis of Variance for Calculating Sr	Appendix X2
Inventory of NIST Rubber Compounding SRMs	Appendix X3

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
