| A: fair resistence; exposure (30 days) to the chemical does not cause any damage. B: sufficient resistence; exposure causes damage of poor importance, which sometimes is only temporary. C: poor resistence; exposure to chemical is not allowed, or causes immediate permanent damage. — Results of testing with reference materials are to be considered as indication: in case of specific use it is recommended to carry out preliminary testing. | |||||
