ASTM D1766-05(2016)

4.1 This test method may be used as a raw material quality-control tool.

1.1 This test method covers a practical test for the solubility of commercial chemicals used in rubber products.

1.2 It is not a true measure of solubility, since equilibrium is not approached from both sides, that is, higher temperature and lower temperature.

1.3 The test method indicates the total solubility, under the conditions of the test, of all components in the presence of each other and in the proportions present in the sample.

1.4 This test method does not measure the solubility of a rubber chemical in rubber.

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

1.6 This standard does not purport to address 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.
