CEN/TC 155/WG 27 - Environmental aspects

This document provides product category rules (PCR) for Type III environmental product declarations, as described in EN ISO 14025 and EN 15942, for plastics piping systems inside the building structures and their main structural components, as specified by the list of product standards provided in Annex CC.
This document encompasses:
-   both pressure and non-pressure applications;
-   metal fittings which are used in a plastic piping system.
The intended function of the system considered is to convey liquids according to EN 806 (for potable water supply), EN 1264 (for heating and cooling systems), EN 12828 (for radiators), EN 12056 (for soil and waste discharge and for water traps).
In case there is no application standard available, this document can also be used for other plastics piping systems such as for example for rainwater gutters, ventilation systems or electrical conduits.
This document specifies product category rules of construction products as defined in and is intended to be used in conjunction with EN 15804+A2.
In addition to EN 15804+A2, this document specifies:
-   the functional unit (consisting of pipes, fittings and ancillary components) and declared unit (consisting of pipes and/or fittings);
-   the system boundaries and additional mandatory modules to be declared;
-   the processes to be included in the installation phase;
-   scenarios for module A4, A5;
-   use conditions for the use phase (B modules);
-   reference service life (RSL);
-   end of life scenarios.

This document provides product category rules (PCR) for Type III environmental product declarations, as described in EN ISO 14025 and EN 15942, for plastic piping systems buried outside building structure and their main structural components, as specified by the list of product standards provided in Annex CC.
Main structural components are:
-   pipes;
-   fittings (e.g. flange couplers, bends and reducers, valves and electrofusion fittings);
-   manholes and inspection chambers (where applicable, e.g. for drains and sewers).
This document encompasses both pressure and non-pressure applications.
The intended function of the system considered is to convey fluids according to EN 476 (for sewers, drain and surface water); EN 805 (water supply), or EN 12007 (gas supply).
In case there is no application standard available, this document can also be used for other plastics piping systems such as cable conduits and surface water piping systems. This document specifies the rules for the product category of construction products as defined in and is intended to be used in conjunction with EN 15804+A2.
In addition to EN 15804+A2, this document specifies:
-   the functional unit (consisting of pipes, fittings, manholes and inspection chambers and ancillary components) and declared unit (consisting of pipes and/or fittings and/or manholes and /or inspection chambers);
-   the system boundaries and additional mandatory modules to be declared;
-   the processes to be included in the installation phase;
-   scenarios for module A4, A5;
-   use conditions for the use phase (B modules);
-   reference service life (RSL);
-   end of life scenarios.

This document provides product category rules (PCR) for Type III environmental product declarations (EPD) as described in EN ISO 14025 and EN 15942 for "plastics piping systems" intended for hot and cold pressure, cold pressure, and soil and waste non-pressure applications inside buildings.
This PCR covers the entire life cycle from cradle to grave.
NOTE   The PCR will be applied to all products covered by CEN/TC 155 in this application. A list of product standards is provided in Annex D.
This document specifies the rules for the product category of construction products as defined in and is intended to be used in conjunction with EN 15804.
In addition to the common parts of EN 15804, this document for European plastics piping systems inside building defines:
-   the functional unit;
-   the system boundaries;
-   the elements and conditions of installations;
-   the transport scenarios for both the raw materials and complete systems;
-   the reference service life (RSL);
-   end of life scenarios.

This document provides product category rules (PCR) for Type III environmental product declarations, as described in EN ISO 14025 and EN 15942, for "buried plastics piping systems" intended for buried pressure and non-pressure applications outside building structure.
This PCR covers the entire life cycle from cradle to grave for buried plastics piping systems conveying fluids (sewer, water or gas), according to EN 12007, EN 805 or EN 476.
NOTE   The PCR will be applied to systems composed of products covered by the list of product standards provided in Annex D.
