Flexible sheets for waterproofing - Environmental product declaration - Product Category Rules for bituminous and synthetic flexible sheets for (roof) waterproofing - Part 1: Cradle to grave

This document provides Product Category Rules (PCR) for the assessment of the environmental
performance of bituminous and synthetic flexible sheets for which the intended use is roof waterproofing.
NOTE The reference product standards are EN 13707 and EN 13956.
This standard shall be used for the development and issue of full cradle to grave EPD’s using
- either generic data and generic system specifications (scenario’s) for Generic EPDs;
- or specific data and specific system specifications (scenario’s), for Specific EPDs.
This PCR includes requirements and rules to:
- define the parameters 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 and the Life Cycle Impact
Assessment underlying an EPD, including the specification of the quality of the applied data;
- define generic data and system specifications which shall be used for Generic EPD.
This standard is developed according to EN 15804 and EN 15942. These European standards
provide the means for developing a Type III environmental declaration of construction products
and they are part of a suite of standards that are intended to assess the sustainability of
construction works.

A construction product may have a number of possible functions. Based on the goal and the scope of an
EPD, the EPD may relate to a specific function and scenario using a functional unit or it may cover a range
of functionalities and scenarios using a declared unit.
6.3.2 Functional unit
The functional unit defines the way in which the identified functions or performance characteristics of
the product are quantified. This allows comparison with other product systems which have been assessed
to fulfil the same functional unit.
2
This document is valid for all roof waterproofing systems with flexible sheets. The functional unit is 1 m
roof waterproofing system.
The reference service life of the roof waterproofing system shall be defined and declared according to
6.3.4.
2
The thickness or mass per m of the sheets shall be expressed according to the applicable product
standard.
For an EPD, whereby a formula to calculate the values for other sheets thicknesses or masses may be
included within the LCA-report and EPD, the formula shall comply with the rules defined in Annex A.
6.3.3 Declared unit
2
The declared unit for roof waterproofing sheets is 1 m .

— The reference service life (RSL) refers to the watertight function of the roof waterproofing system
installed on a building.
— In absence of specific data a default value for the reference service life (RSL) of a roof waterproofing
system of 30 years shall be used. In addition the scenarios for replacement (module B4) and
refurbishment (B5) as defined in 6.3.9.8 shall be used for the calculation.
— The RSL default value or the specific RSL value of the roof waterproofing system with a reference to
the source shall be stated in the EPD.
6.3.5 System boundaries
6.3.5.1 General
EN 15804:2012+A2:2019 shall apply.
