ZHTest Method: SATRA TM343
Contact storage test for discolouration
February 2023
SCOPE
This method is intended to determine the propensity of a material to cause discolouration of another material when stored in close contact. This method is applicable to all materials which are used in intimate contact, and to adhesives which are used to bond them.
PRINCIPLE
Either two dissimilar materials placed in intimate contact or a single piece of material coated with a product such as an adhesive, are placed between glass plates. The assembly is stored in the dark for a prescribed period at an elevated temperature. The test specimens are then examined for any discolouration compared to unexposed reference samples. Discolouration indicates that the materials are likely to discolour under normal service conditions.
