scope:

This document offers product category rules (PCR) guidance for the development of Type III environmental declarations for precast concrete products according to EN 15804. This document defines the parameters to be reported, what EPD types (and life cycle stages) to be covered what rules to be followed in order to generate Life Cycle Inventories (LCI) and conduct Life Cycle Impact Assessment (LCIA) and what quality data to be used in the development of EPDs. Additional to the common parts of EN 15804, this European Standard for precast concrete products: - defines the system boundaries; - defines the modelling and assessment of material-specific characteristics; - defines allocation procedures for multi-output processes along the production chain; - defines allocation procedures for reuse and recycling; - includes the rules for calculating the LCI and the LCIA underlying the EPD; - provides guidance/specific rules for the determination of the reference service life (RSL); - gives guidance on the establishment of default scenarios; gives guidance on default functional units for precast concrete products. This document is intended to be used either for cradle to gate, cradle to gate with options or cradle to grave assessment, provided the intention is properly stated in the system boundary description.
