Resumen:
This draft standard describes the assessment of conformity for multi-layer composite pipes using an alternative material. The original multi-layer composite pipe was assessed within an installation system according to DIN 30655-2. It serves to prove the equivalence of a multi-layer composite pipe, in which the alternative material mentioned is used, with the multi-layer composite pipe within an installation system that has already been fully tested and evaluated in accordance with DIN 30655-1 and DIN 30655-2. The original multi-layer composite pipe must always be used for testing the properties. This standard only applies in conjunction with DIN 30655-1 and DIN 30655-2.
