ISO/TR 7620:2005

ISO/TR 7620:2005 describes a classification system for the reporting and tabulation of the chemical resistance of rubber materials. It also provide guidance on the testing and evaluation of rubber with particular reference to test chemicals described in a number of ISO standards.
It gives guidance on the behaviour of rubber in contact with chemicals such as aggressive gases and fluids, e.g. acids, alkalis, aqueous solutions, oil and solvents.
The information given is based on the practical experience of manufacturers and users of rubber materials.
