European foreword
This document (CEN/TR 16970:2016) has been prepared by Technical Committee CEN/TC 350
“Sustainability of construction works”, the secretariat of which is held by AFNOR.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
Introduction
This Technical Report is a complementary document to EN 15804 “Sustainability of construction
works - Environmental product declarations - Core rules for the product category of construction
products”. It is intended to assist the understanding and use of EN 15804 by giving guidance and
further explanation.
This document does not replace any of the standard’s requirements or introduce any new rules and it
is not intended to be used as a stand-alone document.
This document provides guidance to CEN Technical Committees for construction products and other
bodies such as Environmental Product Declaration programme operators in the construction sector
developing Product Category Rules complementary to EN 15804.
According to decision BT 3/2013, CEN Technical Committees for construction products are asked to
inform CEN/TC 350 at the earliest stage when a complementary PCR document will be developed,
allowing CEN/TC 350 to arrange a liaison and ensure they can review the document when necessary.
1 Scope
This Technical Report provides general guidance to the users of EN 15804 and those preparing
complementary Product Category Rules (c-PCR's) by:
— stating general principles for the use of EN 15804 by CEN Technical Committees for construction
products (Product TC's) in order to ensure consistency among the complementary PCR produced
by Product TC's;
— addressing the questions raised by Product TC's, manufacturers or their sub-contractors who
provide LCA studies underlying an Environmental Product Declaration (EPD) and by EPD
programme operators who include c-PCR of specific subcategories in their PCR registry.
