I would like to ask you, how should we handle the Product safety requirement if our delivered plastic parts has not safety characteristics mentioned on the 2D drawing? In this case, the standard requirements are not applicable? We have only special characteristics, without any safety characteristics.
The requirements for product safety cannot be excluded even if there are no safety issues related to the product. If you are not designing the product and get the drawing from the third party (e.g. customer), they should provide you with information on the product safety. If they don't, you should conduct risk assessment to determine if there are any risks related to the product safety and take appropriate actions. Even if there are no product safety issues, you will still need to have the product safety process.
