VDA 675-244: Elastomere-Bauteile in Kraftfahrzeugen - Prüfverfahren zur Eigenschaftsbestimmung - Wechselwirkung zwischen Kupfer und Elastomeren in Kraftstoffanwendungen / Elastomer
Test Procedure for Identification - Interaction between Copper and Elastomers in fuel applications (Version 11/2020) - Gruppenlizenz (group license), AGB (GTC) Art. 10, 2

This test method describes procedures to determine the interaction between copper surfaces and elastomers that are used in the fuel system and which are not in direct contact. The changes of the copper surface or formed deposits in the test fuel are rated.


The proper working of modules (e.g. electrical contacts) in fuel environment shall be assured by this test method.


Two procedures are defined, which can be used alternatively.

In both cases the elastomer is boiled in the test fluid in presence of copper chips. The filtered solution will be equipped with a copper plate. Alternatively, the solution will be checked for precipitations.


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).

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