The Italian standard is listing all variables that may influence the welding quality and is giving details on the tests that have to be carried,  by third part laboratory,  to ensure that the joint meet the technical characteristics needed.
This feature is very important on the light of the compliance with ISO 9000 requirements because the welding together of polyethylene elements (pipes, fittings, valves, and so on) is a “special process” and as any special process it has to be specified in an official document called WPS (welding process specification).

If you’re interested in the development of your WPS and if you want to qualify the whole process then you may ask help for technical support at uff.comm.estero@plastitaliaspa.com
