The raw material shall be PVC-U to which are added those additives that are needed to facilitate the manufacture of components conforming to the requirements of this European Standard.
The PVC content shall be at least 80 % by mass for pipes and 85 % by mass for injection-moulded fittings and shall be determined by calculation. In case of dispute, the PVC content can also be determined in accordance with EN 1905.
For pipes  110 mm and intended for BD applications, a further reduction of the PVC-U content to  75 % by mass for pipes only is permitted provided the PVC-U is substituted by coated or uncoated CaCO3 conforming to the following:
a) The composition of the CaCO3, before coating if any, shall conform to the following:
1) content of CaCO3  96 % by mass;
2) content of MgCO3 <4 % by mass;
3) content of CaCO3 and MgCO3 in total  98 % by mass.
b) The physical properties of the material shall conform to the following:
1) mean particle size D50 < 2,5 pm;
2)topcutD98≤20μm.
4.2 Additional requirement for pipe material for BD application
The material of pipes intended to be used in application area BD shall comply with the additional requirement given in Table 1, when tested in accordance with the methods and the parameters indicated in Table 1.
The pipe material shall be tested in the form of a pipe.
4.3 Additional requirement for fitting material for BD application
The material of fttings intended to be used in application area BD shall comply with the additional requirement given in Table 2, when tested in accordance with the methods and the parameters indicated in Table 2.
The ftting material shall be tested in the form of an extruded or injection-moulded pipe.
4.4 Utilization of non-virgin material
Conditions and requirements for the tilization of non-virgin material are given in Annex A.BS EN 1329-1 pdf download.
