This document specifies general requirements to be respected in product standards for components such as pipes, fittings, inspection chambers and manholes with their respective joints intended for use in drains and sewers inside and outside buildings which operate as gravity systems allowing for a maximum pressure of 40 kPa.

It also specifies general requirements for components used in hydraulically and pneumatically pressurized discharge pipes, drains and sewers.

NOTE 1 Where the term "inside buildings" is used in the context of components fixed inside buildings, it also includes discharge pipes and fittings fixed on external surfaces of buildings

NOTE 2 This document is not a product standard and therefore not intended for the direct evaluation of products.

This document covers components to be used in conveying in a satisfactory manner:

— domestic wastewater;

— rainwater and surface water; and

— other waste waters acceptable for discharge into the system (e.g. industrial wastewater).

This document applies to components of circular and other cross sections.

This document applies equally to components which are factory-made and to those constructed on site, where applicable.

NOTE 3 This document does not apply to components used for trenchless construction according to EN 14457 and for components used for renovation of drains and sewers according to EN 13380.

This document does not supersede the functional requirements of a complete system as defined in EN 752.

This document describes a test method for laboratory evaluation of possible adverse effects of water treatment membrane elements and modules on drinking water quality.

In principle it is applicable to microfiltration, ultrafiltration, nanofiltration, reverse osmosis and electrodialysis modules for use in the treatment of public water supplies and of water inside buildings.

NOTE Such devices can vary considerably in design and operation and hence some modification of the procedures can be required.

Evaluation of the efficiency of the membrane filter in removing contaminants from the treated water is not included.
