5 Material
5.1 General
The formulation for production of pipes and fittings shall be PVC-U material to which additives are added
to enable conformity with the requirements of this document.
PVC-U material may be virgin material, reworked material or recyclates (pre- or post-consumer).
The dosage level of each ingredient of the formulation shall be specified in the quality documentation by
the manufacturer as part of the material specification.
The maximum amount of recyclate part of the formulation is calculated based on the amount of separate
recyclate added to the formulation plus the amount of recyclate present in reworked material which is
added to the formulation.
Conformity with all the requirements of this document shall be demonstrated.
If recyclates are used, the maximum amount of recyclate in the formulation shall be specified by the
manufacturer and the conformity with all the requirements of this document shall be demonstrated by:
oSIST prEN 1329-1:2024
prEN 1329-1:2024 (E)
a) one formulation with 100 % virgin material and
b) a second formulation consisting the same virgin material as a) and the maximum content of recyclate.
NOTE CEN/TS 1329-2 gives specific recommendation with regard to test frequency when recyclate is used.
Recyclates are permitted if they comply with Annex A.
