Significance and Use

4.1 Certain rubber articles, for example, seals, gaskets, hoses, diaphragms, and sleeves, may be exposed to oils, greases, fuels, and other fluids during service. The exposure may be continuous or intermittent and may occur over wide temperature ranges.

4.2 Properties of rubber articles deteriorate during exposure to these liquids, affecting the performance of the rubber part, which can result in partial failure.

4.3 This test method attempts to simulate service conditions through controlled accelerated testing, but may not give any direct correlation with actual part performance, since service conditions vary too widely. It yields comparative data on which to base judgment as to expected service quality.

4.4 This test method is suitable for specification compliance testing, quality control, referee purposes, and research and development work.

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), (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

1.4 ASTM No. 5 Oil was accepted into Specification D5900 as an industry reference material in 2010 and designated as IRM 905. The composition, and properties of this immersion oil were not changed and the data in Table 1 remains current. Refer to 1.5 The specifications and properties listed in 1.5.1 The subcommittee responsible for maintaining Test Method D471, presently D11.15, shall review the data in Specification D5900 to ensure that it is identical to that which appears in Test Method D471. This shall be accomplished at the time of the 5 year review or more frequently when necessary.

1.6 Historical, technical, and background information regarding the conversion from ASTM No. 1, ASTM No. 2, and ASTM No. 3 Oils to IRM 901, IRM 902, and IRM 903 immersion oils is maintained in Practice D5964.

1.6.1 The subcommittee responsible for maintaining Test Method D471, presently D11.15, shall review the data in Practice D5964 to ensure that it is identical to that which appears in Test Method D471. This shall be accomplished at the time of the 5 year review or more frequently when necessary.
