Historical Standard: ASTM D4678-04(2009)e1 Standard Practice for Rubber - Preparation, Testing, Acceptance, Documentation, and Use of Reference Materials
SUPERSEDED (see Active link, below)
ASTM D4678
1. Scope
1.1 This practice covers materials used on an industry-wide basis as reference materials, which 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.
1.2.1 Important sections of this practice are as follows:
Section | |
Significance and Use | 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.
