This European Standard provides the genera
26、l basis for the preparation or revision of product standards. Some of the provisions may need modifications when drafting harmonized European Standards. It is not applicable for the evaluation of products. It is applicable as a reference for drawing up a product specification, if there is no product
27、 standard available. Components covered are pipes, fittings and joints. This European Standard includes marking, quality control and optional certification requirements. Components are those used in systems that convey in a satisfactory manner: domestic wastewater; rainwater and surface water; other
28、 waste waters (e.g. industrial wastewater) that will not damage the components. This European Standard applies equally to components which are factory-made and to those constructed on site, where applicable. 2 Normative references This European Standard incorporates by dated or undated reference, pr
29、ovisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in i
