DIN EN 14879-1 gives detailed information about the requirements. However, exceptions do exist. For example some plastics are more tolerant to variations than others. On the other hand, specific uses or coating plastics have additional requirements. For this reason we are happy to investigate these individually for you. (open standard summary)
The standard is quite comprehensive. We have compiled a summary for you.
