When calculated on the basis of a known formulation, or in case of dispute or unknown formulation, determined in accordance with EN 1905, the PVC-content shall be at least 80 % by mass for pipes and 85 % by mass for injection-moulded fittings. 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:  content of CaCO3 ≥ 96 % by mass;  content of MgCO3 ≤ 4 % by mass;  content of CaCO3 and MgCO3 in total ≥ 98 % by mass. b) The physical properties of the material shall conform to the following:  mean particle size D50 ≤ 2,5 µm;  top cut D98 ≤ 20 µm.
