The table below presents a general overview of the product requirements for plastic pipes which are covered by:
The requirement level for CE-marked pipes is, as shown below, lower.

decla Manufacturer-declared value required
(1) The manufacturer determines the extent of the internal control
(2) Reaction to fire can be submitted to third party control depending on classification
(3) Water quality is likely to be included in third party type testing and control
(4) Influence on drinking water quality in relation to CE marking is still being discussed, therefore the level in relation to existing requirements in DK and FI is not known
