Scope of application and purpose

This guideline applies to the qualification testing to become a specialist for plastics welding. This proof of the qualification is a prerequisite for the deployment as a welding supervisor in order to ensure the quality of welding work with thermoplastics in tank construction, apparatus engineering, piping construction and dump construction as well as for sealing and lining. In particular, the specialist for plastics welding should be active wherever the customer or the responsible agencies demand his deployment or wherever stringent requirements are set on safety and/or loadability. Furthermore, he is responsible for the scheduled monitoring of the welders through which an extension to the period of validity of the welder qualification test can be achieved. This guideline does not apply to the welding supervision of welding work on pipes and piping parts made of PE-HD in the public gas and water supply or to industrial series welding.
