A new British Standard has recently come into existence which specifies a method of testing the skill and knowledge of welders involved in the repair or construction of thermoplastic structures.
BS EN 13067 Plastics welding personnel - Qualification testing of welders - thermoplastics welded assemblies covers the principles to be observed in the qualification testing of welder performance.
The skill of a welder is an essential condition to assure the quality of the welding work and application of this standard guarantees that the examination is carried out according to a uniform procedure.
The standard applies to the welding of sheet, pipe, fittings and lining membranes, using the following welding processes:
- Hot gas welding
- Extrusion welding
- Heated tool (butt and socket fusion, wedge)
- Electrofusion
TWI runs internationally recognised CSWIP examinations, aligned to BS EN 13067, at TWI North in Middlesbrough or on site worldwide.
