This European Standard specifies general requirements and general test methods for - components such as pipes and fittings with their respective joints, manholes, inspection chambers and - materials such as mortar and chemicals all intended to be used for repair and renovation of drain and sewer systems. These drain and sewer systems generally operate as gravity drainage systems where any pressure likely to occur is a maximum of 40 kPa and which are generally buried. This European Standard provides the general basis for the preparation and revision of volontary product standards. It is not applicable for evaluation of products. It applies as a reference for drawing up a product specification, if there is no product standard available. This European Standard includes quality control and optional certification requirements. It applies to components those used in systems that convey in a satisfactory manner: - domestic wastewater; - rainwater and surface water; and - other waste waters (e.g. industrial waste water) that will not damage the components. This European Standard applies to components of circular and other cross sections. This European Standard applies equally to components which are factory-made and to those manufactured on site, where applicable.
