ASTM International has just released the new ASTM D471-12, “Standard Test Method for Rubber Property—Effect of Liquids,” and it’s available now from Document Center Inc. in paper, pdf and redline format. This test method covers the required procedures to evaluate the comparative ability of rubber and rubber-like compositions to withstand the effect of liquids.
This 14-page revision is designed for testing specimens of vulcanized rubber cut from standard sheets, specimens cut from fabric coated with vulcanized rubber, or finished articles of commerce. It is not applicable to the testing of cellular rubbers, porous compositions, and compressed sheet packing.
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.
Properties of rubber articles deteriorate during exposure to these liquids, affecting the performance of the rubber part, which can result in partial failure.
ASTM D471 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.
This test method is suitable for specification compliance testing, quality control, referee purposes, and research and development work. It replaced the old Federal Specification TT-S-735, “Standard Test Fluids, Hydrocarbon,” back in September, 1998.
