Standards Development

Scope

This document defines Product Category Rules (PCR) providing guidelines and rules for developing a type III environmental declaration (as in EN 15804:2012+A2:2019) for rough natural stone blocks and slabs and natural stone products for internal and external floorings and walls coverings, facade cladding and dimensional stones used for diverse purposes (e.g. window sills, columns, railings, kitchen tops).

The scope of this c-PCR specifically includes:

- Intermediate products: Rough blocks and rough slabs resulting from the Quarrying environment, for which the environmental assessment focuses primarily on the Production Stage (Modules A1-A3), in accordance with the provisions for intermediate products in EN 15804.

- Processed products: Semi-finished and finished stone products resulting from manual or machine processing.

This c-PCR excludes agglomerated stone with artificial binders (EN 14618) and engineered stone.

NOTE The assessment of social and economic performances at product level is not covered by this standard.

The cPCR:

— defines the indicators to be declared, information to be provided and the way in which they are collated and reported,

— describes which stages of natural stones life cycle are considered in the EPD and which processes are to be included in the life cycle stages;

— defines rules for the development of scenarios;

— includes the rules for calculating the Life Cycle Inventory and the Life Cycle Impact Assessment underlying the EPD, including the specification of the data quality to be applied;

— includes the rules for reporting predetermined, environmental and health information, that is not covered by LCA for a natural stone construction process and construction service where necessary;

— defines the conditions under which natural stone can be compared based on the information provided by EPD.

Purpose

The main purpose is to prepare a standard for natural stones to comply with EN 15804.
