The purpose of this NORDTEST method is to find out if elastic rubber sealing rings used in plastic pipe systems contain components (i.e. softeners like dioctylphthalate in rubber rings in connections with PVC, subsidiary materials in connection with the production, stabilizers, etc.) which have a harmful influence on the plastic material.
