VDA 675-240: Elastomere-Bauteile in Kraftfahrzeugen - Prüfverfahren zur Eigenschaftsbestimmung - Anklebeverhalten von Elastomeren an Glas, lackiertem Blech oder anderen Oberflächen / Test Method to Determine Properties - Adhesion of Elastomers to glass, painted sheet metal or other mating materials (Version 08/2020) - Gruppenlizenz (group license), AGB (GTC) Art. 10, 2
This standard provides a means for the determination of adhesion of elastomeric parts of body sealings, which may occur between an elastomer and glass, painted sheet metal, or other surfaces when in contact.
Two different test methods are defined:
Method A: Test Procedure for glass plate or painted sheet metal as mating substrate. Test pieces of elastomers are held in contact with the respective mating substrate under a specified deflection at (90 + 2) °C. The adhesion force FA required to separate the elastomer from the mating substrate is then determined. Tests are carried out on test pieces in the "as received" condition, and also when exposed to specified liquids.
Method B describes a single adhesion test without determination of forces.
