This document specifies the testing conditions to assess the treatment performances of greywater systems. Excluded from the scope of this document are: - the testing of rainwater harvesting systems; - the testing of systems for direct use as mentioned in EN 16941–2 "On-site non-potable water systems - Part 2: Systems for the use of treated greywater"; - the testing of blackwater treatment systems; - the testing of wastewater treatment plant.

This document is part of a System Standard for plastics piping systems of a particular material for a specified application. System Standards are based on the results of the work being undertaken in ISO/TC 138 "Plastics pipes, fittings and valves for the transport of fluids", which is a Technical Committee of the International Organization for Standardization (ISO). They are supported by separate standards on test methods to which references are made throughout the System Standard. The System Standards are consistent with general standards on functional requirements and on recommended practice for installation. This document does not cover sewage pump chambers, valve chambers and similar products. This document specifies the definitions and requirements for unplasticized polyvinyl chloride (PVC-U), polypropylene (PP) and polyethylene (PE) manholes and inspection chambers having a base with a flow channel and their joints to the piping system, intended for use in non-pressure underground drains and sewers for wastewater, up to a maximum depth of 6 m from ground level to the invert of the flow channel. This document is applicable to manholes and inspection chambers, intended for use buried in the ground outside a building structure only; reflected by the marking of products by "U". This document is applicable to manholes and inspection chambers intended for use in pedestrian or vehicular trafficked areas. NOTE 2 Products complying with this document can also be used in non-traffic areas. NOTE 3 Products complying with this document can be installed in underground applications without additional static calculation. Manhole and inspection chamber components can be manufactured by various methods e.g. extrusion, injection moulding, rotational moulding, low-pressure moulding or factory fabricated. Manholes and inspection chambers complying with EN 13598-2 are made from a prescribed set of components that are assembled together or manufactured as a single unit. NOTE 4 The complete manhole or inspection chamber assembly also includes items which are not specified in this document (for example near surface or surface components such as covers, frames and gratings complying with the relevant part of EN 124[1]). NOTE 5 Manholes and inspection chambers can be subject to national regulations and / or local provisions.

This document specifies requirements and test methods for pipes and fittings which are part of piping systems for the renovation of underground non-pressure drainage and sewerage networks. It is applicable to pipes, fittings and assemblies, made from thermoplastic composite materials, as manufactured and as installed. It is not applicable to the existing pipeline. It is applicable to technique families for renovation: — lining with spirally-wound (SWO) pipes; — lining with a rigidly anchored plastic inner layer (RAPL). and intended to be used at an operating temperature of 20 °C as the reference temperature. In the case of lining with SWO pipes, where the pipes, are formed on site, to a fixed or variable diameter, by spirally winding and jointing a pre-manufactured profiled plastics strip, this document applies to, strips made of unplasticized poly(vinyl chloride) (PVC U), or of polyethylene (PE), with or without steel stiffening elements, and installed with or without integral locking mechanism. In the case of lining with RAPL, where a single rigid annulus of structural cementitious grout is formed behind a plastics inner layer serving as permanent formwork anchored to the grout. This document applies to integrally joined profiled plastics strips of PVC-U or PE or studded sheets of PE, and grout systems with or without steel reinforcement. It does not apply to the structural design of the lining system. NOTE Systems with multiple annuli are available, but these are controlled by patent rights and not covered by this document.
