ASTM D471 Standard Test Method for Rubber Property - Effect of Liquids
1. Scope
1.1 This test method covers the required procedures to evaluate the comparative ability of rubber and rubber-like compositions to withstand the effect of liquids. It is designed for testing: (1) specimens of vulcanized rubber cut from standard sheets (see Practice D3182), (2) specimens cut from fabric coated with vulcanized rubber (see Test Method D751), or (3) FInished articles of commerce (see Practice D3183). This test method is not applicable to the testing of cellular rubbers, porous compositions, and compressed sheet packing, except as described in 11.2.2.
1.2 ASTM Oils No.2 and No.3, formerly used in this test method as standard test liquids, are no longer commercially available and in 1993 were replaced with IRM 902 and IRM 903, respectively (see Appendix X1 for details).
1.3 This test method includes the following:
Change in Mass (after immersion): Section 10
Change in Volume (after immersion): Section 11
Dimensional-Change Method for Water-Insoluble Liquids and Mixed Liquids: Section 12
Change in Mass with Liquid on One Surface Only: Section 13
Determining Mass of Soluble Matter Extracted by the Liquid: Section 14
Change in Tensile Strength, Elongation and Hardness (after immersion): Section 15
Change in Breaking Resistance, Burst Strength, Tear Strength and Adhesion for Coated Fabrics: Section 16
Calculation (of test results): Section 17
1.4 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.
1.5 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.
