ASTM D471-06e1 PDF

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 D 3182), (2) specimens cut from fabric coated with vulcanized rubber (see Test Methods D 751), or (3) finished articles of commerce (see Practice D 3183). 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 ASTM No. 1 Oil, previously used in this test method as a standard test liquid, is no longer commercially available and in 2005 was replaced with IRM 901; refer to Table 1, Footnote A, and Appendix X3 for details.

1.4 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 Liq-
uids and Mixed Liquids
Section 12 Change in Mass with Liquid on One Surface OnlySection 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 18

1.5 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.

1.6 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.
