scope:

This Guideline applies to the heated plate welding of panels according to DIN EN ISO 14632 and the heated plate welding, socket welding and sleeve welding according to DIN 8074, 8075, DIN EN 12201, DIN EN 1555, DIN EN ISO 15494 of pipes, fi ttings and saddle-type connections made out of polyethylene 1) and which are used for the conveying of gases, liquids and solids. Assuming adherence to the following instructions, then suitability within the melt mass fl ow rate MFR 2) 190/5 of 0.20 to 1.70 g/ 10 min can be assumed. The restrictions set out in section 4.2 must be observed when carrying out heated plate welding of saddletype connections.

In the event of a diff ering melt mass fl ow rate, the Suitability Certifi cate is to be updated following a tensile creep test in line with Technical code DVS 2203-4 or Supplement 1.
