This document provides product category rules (c-PCR), that are complementary to EN 15804:2012+A2:2019, for Type III environmental declarations for gypsum-based products for the construction industry. This document: — specifies the functional and/or declared unit to be used; — defines the default system boundaries for gypsum-based construction products; — defines allocation procedures for the environmental impact of recycling and/or the use of by-products; — describes the default scenarios and rules for defining scenarios for each of the life cycle information modules A-D; — provides guidance for the determination of the reference service life (RSL) for gypsum-based construction products. NOTE 1 Annex B of EN 15804:2012+A2:2019 has been complemented in an annex to this document. NOTE 2 An Annex F has been added to this document.
