The following information has to be included in each packing unit:
smallest permissible bending radii
area-related oxygen permeability of ≤ 0.32 mg / (m²·d) at 40 ° C (application class 4) or ≤ 3.60 mg / (m²·d) at 80 ° C (application class 5)
Heating water additives, if applicable
The pipes must be delivered protected from light. To prevent damage and adverse effects due to UV radiation, the tubes must be stored in the packaging until they are laid. Otherwise, they have to be protected against these influences in other ways. This must be indicated in the product documentation and in the leaflet.
