This Technical Report 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.
This document 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 in this document is based on the practical experience of manufacturers and users of rubber materials.
Unless there is prior knowledge or experience of the application, a selection based on the tables should always be confirmed by tests on the proposed rubber compounds using the actual product under the appropriate service conditions. In such tests, attention should also be given to the possibility of the rubber material contaminating the liquid or gas.
