Information:
A piping may only be commissioned after successful pressure test (see
EN 805, EN 12007 and DVGW G 469, W 400). The guidelines of the
DVGW leaflets for pressure tests, the European standards or the
country-specific regulations are to be observed.
Information:
The detachment of the outer armouring wire during the cooling down
stage is caused by the thermal expansion characteristics of the fused
joint and does not present a problem.
