| Title | Plastics piping systems inside the building structure - Environmental product declarations - Product category rules complementary to EN 15804 |
| Work Item Number | 00155A0L |
| Abstract/Scope | 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. |
