European foreword
This document (EN 17074:2019) has been prepared by Technical Committee CEN/TC 129 “Glass in
building”, the secretariat of which is held by NBN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by April 2020, and conflicting national standards shall be
withdrawn at the latest by April 2020.
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.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,

Introduction
This document provides Product Specific Category Rules for flat glass products (Flat Glass PCR) used in
buildings and other construction works to support the assessment of the environmental performance
and the development of Environment Product Declarations.
This Flat Glass PCR aims at complementing the general rules established in EN 15804:2012+A1:2013,
by providing additional detailed rules on technical and environmental aspects of the manufacture of flat
glass products, as well as information on relevant aspects linked to use and end-of-life stages, on a
harmonized and scientific basis.
It specifies the requirements for the Life Cycle Assessment (LCA) study and the format and content of
the EPD itself.
In the Environment Product Declarations, the information is presented by way of a modular approach,
which allows for the easy organization and expression of data packages throughout the life cycle stages
of the product. The approach requires that the underlying data should be consistent, reproducible and
comparable.
1 Scope
This document covers all life cycle stages, from cradle to grave, namely product stage, construction
process stage, use stage and end-of-life stage of glass products (see Clause 4), used in buildings.
While covering all life cycle stages, this PCR primarily focuses on the product stage, in particular the
manufacturing of flat glass and the consequent processing into flat glass products (as listed in point 4.),
from cradle to gate. It covers raw materials and energy supply, transport, flat glass manufacturing, flat
glass processing, packaging and storage.
All requirements and recommendations in this PCR for the elaboration of the Life Cycle Inventory may
be applicable to flat glass used in other applications.
This PCR includes the rules to produce EPD that contains more than one thickness or configuration of
the same product.
