VDA 675-305: Elastomer Beständigkeit - Bestimmung des Verhaltens gegen Prüffette / Test Method to determine resistances - Determination of the effect of greases (Version 05/2020) - Gruppenlizenz (group license), AGB (GTC) Art. 10, 2

The object of this test method is to determine the changes in properties on elastomers, caused bythe action of greases.

This test method can provide data for

-      qualification tests on different elastomers which are in question for a specific application (quality determination),

-      comparison tests on different delivery batches of a specific elastomer compound (quality assurance).

Tests are performed preferably with the test pieces described in section 3.1. With regard to the influence of test piece shape (thickness, volume, aspect ratio and others) and the nature of the test piece (vulcanization skin on one side or all-round, ground surface and others) the tests can be performed on finished parts as well.

Standard dumbbells Type 3 and Type 4 to ISO 37 are permissible for the testing of finished parts.The usage of other specimen, e.g. whole finished parts or sections of finished parts, must be agreed upon.

Test comparisons can only be done on test pieces with same geometry.

The time between vulcanization and testing of elastomers shall be at least16 h and not longer than 6 months when investigating to this procedure.
