Standards Development

Scope

This document provides product category rules (PCR) guidance for the development of Type III environmental declarations for masonry units according to EN 15804+A2:2019

This document defines the parameters to be reported, the EPD types (and life cycle stages) to be covered, the rules to be followed in order to generate Life Cycle Inventories (LCI) and conduct Life Cycle Impact Assessment (LCIA) and the data quality to be used in the development of EPDs.

In addition to the common parts of EN 15804+A2:2019, this European Standard for masonry 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;

gives guidance on the establishment of default scenarios; gives guidance on default functional units for masonry units.

This document is intended to be used for cradle to gate, cradle to gate with options or cradle to grave assessments, when the intention is clearly stated in the system boundary description. 

Purpose

This European Standard provides rules for Environmental Product Declarations (EPD) for masonry units. It complements the core product category rules for all construction products and services given in EN 15804 +A2:2019. Sustainability of construction works - Environmental product declarations - Core rules for the product category of construction products. This European Standard provides additional rules for Environmental Product Declarations (EPD) of masonry units. It complements the core rules for all construction products and services as established in EN 15804:2012+A2:2019.

Note: in case the WI is based on documents from other organizations than ISO/IEC, please specify it here
