In this revision, the scope of this standards includes solvent welding: socket and covers the welding of the polypropylene (PP) lining membranes (group 9: PP).

According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

Introduction

This standard covers the principles to be observed in the qualification testing of welder performance for the welding of thermoplastic materials.

The ability of the welder to follow verbal or written instructions and testing of his skill are important factors in ensuring the quality of the welded product.

This standard is intended to provide the basis for the mutual recognition by examining bodies for qualification relating to welders competence in the various fields of application.

1 Scope

This European Standard specifies the method of testing the knowledge and skill of a welder who is required to carry out welds on thermoplastics in new constructions and repair work.

The skill examination of a welder is an essential condition for the assurance of the quality of the welding work.

The application of this standard guarantees that the examination is carried out according to a uniform test procedure.

This European Standard applies when the contractor or the authorities responsible for the application require it.

Gas and water utility network industries with alternative qualification programmes are excluded from this standard.

This European Standard applies to the following welding processes:

hot gas welding: round nozzle, high speed nozzle, wedge;
extrusion welding;
heated tool welding: butt, saddle, socket, wedge;
electrofusion welding: socket, saddle;
solvent welding: socket.

This European Standard applies to the welding of the following products:

sheet;
pipe;
fittings;
lining membrane.

This European Standard covers the welding of the following groups of materials:

for sheets, pipes and fittings:
1. group 1: PVC (including all kinds of PVC-U, PVC-C), ABS;
2. group 2: PP (including all kinds of PP);
3. group 3: PE (including all kinds of PE);
4. group 4: PVDF;
5. group 5: ECTFE or PFA or FEP;
for lining membranes:
1. group 6: PVC-P;
2. group 7: PE (including all kinds of PE);
3. group 8: ECB;
4. group 9: PP.
