The ASTM D471-98e2 standard, developed by the American Society for Testing and Materials (ASTM), defines test methods for evaluating the comparative ability of rubber and rubber-like compositions to withstand the action of liquids.
This standard is designed for testing the following materials:
This test method is not applicable to testing cellular rubbers, porous compositions and compressed sheet packaging.
The ASTM oils (No. 2 and No. 3) previously used as standard test fluids in this testing method are no longer commercially available and have been replaced by IRM 902 and IRM 903, respectively.
The test method described in the ASTM D471-98e2 standard includes:
Some rubber materials, such as gaskets, hoses, diaphragms and sleeves, are exposed to oils, greases, fuels and other fluids during service. Exposure may be continuous or intermittent and may occur over wide temperature ranges. The properties of rubber materials deteriorate when exposed to these liquids. This affects the performance of the rubber material, which causes malfunction.
Exposure to liquids occurs either during use or by contact during packaging or transportation.
When the tests are complete, the description and origin of the specimen, the temperature of the test environment, the curing time and temperature of the test specimens, the dates of the various exposure periods, the immersion liquid used, the exposure temperature, the exposure time, all observed and recorded data, the test method used to determine the hardness, and the standard Any deviations from test methods are reported.
Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides standard testing services for the rubber property effect of liquids, within the scope of ASTM D471-98e2 standard, with its trained and expert staff and advanced technological equipment.
