European foreword
This document (prEN 17388-2:2022) has been prepared by Technical Committee CEN/TC 254 “Flexible
sheets for waterproofing”, the secretariat of which is held by NEN.
This document is currently submitted to CEN Enquiry.
EN 17388, Flexible sheets for waterproofing - Environmental product declarations - Product category rules
for reinforced bitumen, plastic and rubber flexible sheets for roof waterproofing, consists of the following
parts:
— Part 1: Cradle to grave and module D
— Part 2: Cradle to gate with options, modules C1-C4 and module D

Introduction
CEN TC 254 has decided to provide this European standard in 2 parts. The scope of these different parts
is based on the different types of environmental product declarations (EPD) identified by
EN 15804:2012+A2:2019. This will avoid misinterpretation in the market about the EPD scope and
content.
This European standard consists of two parts:
— Part 1: cradle to grave and module D;
— Part 2: cradle to gate with options, modules C1-C4 and module D.
NOTE 1 The clauses and sub clauses with exception of the annexes are corresponding with the clauses and sub
clauses of EN 15804:2012+A2:2019.
NOTE 2 Cradle to grave and module D. All modules A, B, C and D are mandatory.
NOTE 3 Cradle to grave with options, modules C1-C4 and module D. Modules A1-A3, C and D are mandatory,
additional modules A4-A5, B1-B7 are optional.
NOTE 4 For further information see Annex B.

1 Scope
This document provides product category rules (PCR) for the assessment of the environmental
performance of reinforced bitumen, plastic and rubber flexible sheets for which the intended use is roof
waterproofing.
NOTE The reference product standards are EN 13707 and EN 13956.
This document is intended to be used for the development and issue of a cradle to gate with options,
modules C1-C4 and module D EPD using specific data. This document includes requirements and rules
to:
— define the indicators to be declared and the way in which they are collected and reported;
— describe which stages of a product’s life cycle are considered in the EPD and which processes are to
be included in the life cycle stages;
— include the rules for calculating the life cycle inventory (LCI) and the life cycle impact assessment
(LCIA) underlying an EPD, including the specification of the quality of the applied data.
2 Normative references

assembly of one or more sheets in its applied and jointed form to prevent the passage of water from one
plane to another, which has certain performance characteristics, to be assessed as a whole, to be used in
the roof of a building, including roofs used for parking of vehicles and for roof gardens
3.6

For the purposes of this document, the symbols and abbreviations given in EN 15804:2012+A2:2019
shall apply.
5 General aspects
5.1 Objective of the PCR
In addition to EN 15804:2012+A2:2019, 5.1, this document defines the requirements on information,
data and environmental indicators that shall be included in an environmental product declaration (EPD)
for a cradle to gate with options, modules C1-C4 and module D EPD using specific data for:
— roof waterproofing systems with reinforced bitumen flexible sheets for roof waterproofing according
to EN 13707;
or
— roof waterproofing systems with plastic and rubber flexible sheets for roof waterproofing according
to EN 13956.
5.2 Types of EPD with respect to life cycle stages covered
In addition to EN 15804:2012+A2:2019, the following shall apply.
The LCA based information in an EPD shall cover (see EN 15804:2012+A2:2019, Figure 1) the life cycle
of a product according to the system boundary (see 6.3.5). In this case, the EPD covers the product stage,
the end-of-life stage and benefits and loads beyond the system boundary and can cover construction
process stage and use stage.
5.3 Comparability of EPD for construction products
EN 15804:2012+A2:2019 shall apply.
