scope:
This technical code applies to the heated tool butt welding of sheets according to DIN EN ISO 14632 and for the heated tool butt-, the heated tool socket- and the electro-socket welding of pipes, fittings and tapping tees made from PE-HD1) according to DIN 8074 and 8075, DIN 16 963, DIN 3543-4 and DIN 3544-1, being used for the conduction of gas, fluids and solids.
With regard to the following instructions, suitability within the melt flow rates MFR2) 190/5 of 0,3 up to 1,7 g/10 min or 0,2 up to 0,7 g/10 min respective may be assumed. For the heated tool butt welding of tapping tees restrictions according to section 4.2 have to be attended.
Deviating MFR values require an additional proof by tensile creep tests according to DVS 2203-4 or supplement 1.
1) The material indication is the specification of thermoplastics group and includes the types PE 63, PE 80 and PE 100. The information complies to the current standards.
2) old indication MFI = Melt Flow Index
