scope:
This Technical Code applies to the heated plate welding of panels according to DIN EN ISO 15013 and the heated plate welding, socket welding sleeve welding according to DIN 8077, DIN 8078, DIN EN ISO 15494 and DIN EN ISO 15874 of pipes, fi ttings and saddle-type connections made out of polypropylene PP-H, PP-B and PP-R 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 190/5 of 0.4 to 1.0 g/10 min can be assumed.
This range roughly corresponds to a melt mass fl ow rate MFR 230/2.16 of 0.2 to 0.6 g/10 min. In the event of diff ering melt mass fl ow rates, the Suitability Certifi cate is to be updated following a tensile creep test in line with Technical Code DVS 2203-4 or Supplement 1.
