Product category rules for life cycle assessments of electronic and electrical products and systems
This document defines product category rules (PCR) for electronic and electrical products and systems (EEPS).
It specifies the process and requirements on how to conduct life cycle assessment in the context of
environmental declarations.
PCR is complemented by additional product-specific rules (PSR), which further define e.g. functional units and
default scenarios in the product-specific context. Therefore, it also provides guidance on how to develop PSR
in corresponding technical committees.
This document provides common rules for:
a) life cycle assessment (LCA), including the requirements for developing default scenarios;
b) the LCA report;
c) the development of product specific rules.
This document provides further guidelines for environmental declarations.
The basic LCA principles and framework are based on the EN ISO 14040 series of standards (i.e EN ISO 14040
and ISO 14044), and therefore out of scope of the standard.

European foreword
This document (EN 50693:2019) has been prepared by CLC/TC 111X “Environment”.
The following dates are fixed:
• latest date by which this document has (dop) 2020-08-12
to be implemented at national level by
publication of an identical national
standard or by endorsement
• latest date by which the national (dow) 2022-08-12
standards conflicting with this document
have to be withdrawn
The TC 111X Working Group 8 has been assigned to deal with the NWIP to define product category core rules
for life cycle assessment as basis for environmental declarations. This document has been elaborated to ensure
a harmonized and compatible approach through harmonized methods of assessing the environmental
performance and providing environmental declarations for electrical and electronic products and systems
(EEPS).
Key points:
a) requirements how to conduct life cycle assessments for environmental declarations;
b) requirements how to compile an associated life cycle assessment report;
c) requirements how to develop product specific rules in vertical, product specific technical committees.
It is the intention of the working group that this document, once finalized as European standard, will be further
processed to an international consensus in IEC according to the UAP procedure agreement between CENELEC
and IEC.
Future standards defining product specific rules have to be consistent with this standard during their preparation.
Any product specific standard already including these topics, e.g. EN 50598-3, should adapt their content to this
standard within their usual maintenance circles.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CENELEC shall not be held responsible for identifying any or all such patent rights.
Introduction
In the recent years, environmental aspects of electrical and electronic products and systems gained in
importance for interested parties, such as customers and regulators.
In addition to qualitative approaches already widely applied in the context of environmental conscious design
process, quantitative information on the potential environmental impacts of the full life cycle of products gained
further interest. This generates the need to provide harmonized rules for the underlying life cycle assessment
(LCA) in order to provide robust and consistent quantitative environmental data on electrical and electronic
products and systems (EEPS), as well as to enable data aggregation at system level, like e.g. buildings, power
drive systems and control cabinets.
The definition of product category rules (PCR), derived from EN ISO 14025, is an established method for a
consistent approach by setting minimum quality standards for life cycle assessment in context to environmental
product declarations (EPD) and hence are now defined as core rules in this standard for the variety of electrical
and electronic products and systems.
On the base of the overarching PCR set out as core rules for EEPS, product specific rules (PSR) should be
elaborated to further detail the requirements for the LCA in the specific context of the products or systems in
scope. This can be done e.g. by product specific standardization committees or environmental declaration
programs.
1 Scope
This document defines product category rules (PCR) for electronic and electrical products and systems (EEPS).
It specifies the process and requirements on how to conduct life cycle assessment in the context of
environmental declarations.
PCR is complemented by additional product-specific rules (PSR), which further define e.g. functional units and
default scenarios in the product-specific context. Therefore, it also provides guidance on how to develop PSR
in corresponding technical committees.
This document provides common rules for:
a) life cycle assessment (LCA), including the requirements for developing default scenarios;
b) the LCA report;
c) the development of product specific rules.
This document provides further guidelines for environmental declarations.
The basic LCA principles and framework are based on the EN ISO 14040 series of standards (i.e EN ISO 14040
and ISO 14044), and therefore out of scope of the standard.

4 Product life cycle assessment
4.1 General
To quantify the potential environmental impacts caused by EEPS, LCA compliant with EN ISO 14040 and
EN ISO 14044 shall be performed. And results can then be used to identify improvement potentials in terms of
e.g. environmental conscious product design. In addition, the requirements of this PCR and applicable PSR
shall be applied in case the LCA results are further intended to be used in external communication. This is valid
when the form of an environmental product declaration (EPD), as laid out in the EN ISO 14021/14025 standards,
is used.
4.2 Product Category Rules
4.2.1 General
The product category rules (PCR) provide a uniform approach to perform the LCA, serving three purposes:
— to ensure a consistent quality of the LCA results,
— to enable data aggregation in larger systems, e.g. buildings or industrial production machinery,
— to serve as basis for environmental declarations using quantitative environmental impacts.
The PCR should be complemented with corresponding, product specific rules (PSR) to further specify
assumptions and methodology to be used for specific product families.
Product PSR shall be developed in the respective product technical committees according to the requirements
set out in this standard. If there are no PSR available yet but there’s the need for quantitative environmental
information based on LCA for a certain product group, the LCA practitioner shall complete the missing
specifications according to the requirements of EN ISO 14044 and shall disclose his specifications along with
the evaluated data.
NOTE For the completion of the missing information various sources might be available, like for instance environmental
declaration programs or PSR in standards by other product groups.
4.2.2 Functional unit and reference flow description
A product or system may have several functions and the main function(s) delivered to the user shall be selected
for the LCA study.
The functional unit (FU) is the product or system main function(s)’ quantified, to which the inputs and outputs
are related to.
The functional unit shall be defined by:
a) The main function(s) delivered to the user;
b) The magnitude and level of performance to be achieved for the main function(s). This level shall be
quantified and determined according to the market habits, regulatory requirements, standards and/or the
technical state of the art;
c) the reference service life (RSL) for the reference product, corresponding to the stipulations set out in ii).
The FU is used as a reference unit to allow comparison between different alternatives (e.g. products, systems
or technical solutions) intended to provide the main functions with the required level of performance.
NOTE 1 Some products or systems may have complex FU descriptions, for example multifunctional products such as
smartphones.
In PSR development it shall be taken into account that the definition of the RSL could lead to distortions for
product groups with a considerable range of product life span, where for some products the environmental
impacts would be underestimated, while for others it would be overestimated. Hence this should be reflected in
the FU and RSL, as well as the EPD, e.g. by providing annualised data.
Examples of functional units:
1) Motor: To provide (50 kW) of (mechanical power), over (20) years RSL with (260) days of operation per
year and (16) operating hours per day.
2) Cables (Energy distribution networks in the area of infrastructures): To transmit energy expressed for 1A
over a distance of 1 km for 40 years and a 100 % use rate in accordance with relevant standards (mention
the relevant standards or refer the product technical data sheet).
NOTE 2 Examples taken from CENELEC TC2 Working Group and PEP Ecopassport declaration program. (PCR ed3 -
PSR-0001-ed3-EN-2015 10 16)
Each functional unit shall be further specified in product specific rules (PSR) for each product or system family
to allow fair assessment and comparison. If no PSR is available, the FU shall be defined and documented
according to the requirements mentioned above and ISO standards EN ISO 14040 / EN ISO 14044.
The reference flow describes all the needed flows to fulfil the functional unit. A specific reference flow matches
each specific technical solution fulfilling the functional unit.
The reference flow shall include:
a) The quantitative amount of product(s), e.g. specified through their mass in kg, used to fulfil the functional
unit: they will be named “reference product”;
b) In addition, intermediate flows, for instance auxiliary materials and packaging, including waste and
discarded materials generated at each life cycle stage.
This relationship between functional unit, technical solution and reference flow is further illustrated in Figure 1
through an example.
Figure 1 — Graphical visualization of functional unit, technical solution and reference flow relationship
Since this reference flow is very product-system specific it shall be described in detail in product specific rules
(PSR).
A product may have several possible functions. Based on the goal and scope of the conducted LCA, the LCA
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 (DU). The declared unit shall be used as an alternative to the functional unit
if no functional unit can be defined. This is the case when the product can be used in many different ways in the
context of its application, or when the precise function of the product or scenarios of the system in which it is
integrated is not stated or is unknown.
The declared unit shall clearly mention:
a) The quantity of product;
2 3
b) The unit used (item, mass (kg), length (m), area (m ), volume (m ));
c) The mathematical relation between functional unit and declared unit, if applicable.
If a DU is used, it shall be documented accordingly in the LCA report.
If relevant, the DU shall be specified further in the corresponding PSR.
4.2.3 System boundary
4.2.3.1 General
LCA is conducted by defining product systems as models that describe the key elements of the physical systems.
The system boundary then defines the unit processes that shall be included in the product system.
In this context it should be noted, that the product system used as a term in LCA may be different from the
understanding of a product system as for instance used in engineering.
The life cycle of the EEPS under study shall at least cover the following main life cycle stages:
a) Manufacturing stage, including the relevant upstream process (e.g. acquisition of raw material, preparation
of semi-finished goods etc.) and the main manufacturing and processing steps;
b) Distribution stage
c) Use stage, including the required maintenance steps within the RSL associated to the reference product;
d) End-of-life stage, including the necessary steps until and for the final disposal or recovery of the product
system.
Additionally, the following life cycle stages can be relevant and should then be considered in the LCA
accordingly:
e) Installation stage, including the relevant steps for the preparation of the product for use;
f) De-installation, including the relevant steps for the preparation of the product for end-of-life;
The LCA shall include all relevant flows to the system, as energy and material resources and from the system,
as emissions to air, soil, water and waste, allocated to the respective life cycle stage.
Figure 2 — Scheme of the analysed product system’s boundaries, including the life cycle stages and
unit processes, which separate it from the ecosphere (natural environment)
Each life cycle stage includes all the aspects related to its inputs and outputs. For example, regarding waste
management, each stage includes the production, transportation, treatment and disposal of the waste generated
at the considered stage (discarded products, materials, etc.).
Further specifications concerning the system boundary shall be defined in the PSR.
4.2.3.2 Exclusions from System Boundary
The capital goods, such as buildings, machinery, tools and infrastructure, the packaging for internal transport
(i.e. boxes use to transport parts, components to the assembly point) and administrative overhead activities (e.g.
Business travel, marketing and advertisement…,), which cannot be allocated directly to the production of the
reference product, may be excluded from the system boundary.
4.2.3.3 Cut-off criteria
Criteria for the exclusion of inputs and outputs (cut-off criteria) in the LCA are intended to support an efficient
calculation procedure. They shall not be applied to hide data.
Based on established LCA practice, the cut-off criteria are set to a maximum of 5 % of the overall environmental
impact of the analysed product system given by its life cycle impact assessment (LCIA) results. Details
concerning cut-off criteria may be developed, defined and justified in PSR based on e.g. conducted LCA case
studies or compiled from literature and research papers. These PSR may address cut-off by defining criteria for
mass and energy cut-off, and / or main (and auxiliary) products parts, which are mandatory for the life cycle
assessment. Therefore, PSR can be stricter and more specific in that context. Any exclusion of inputs and
outputs shall be documented and justified.
4.2.4 Life cycle inventory
4.2.4.1 General
This section defines the inputs and outputs corresponding to the aspects of each of the life cycle stages that
shall be considered in the LCA. Further details concerning the modelling of the life cycle stages are laid out in
4.3 of this standard concerning the development of scenarios. The relevance of the life cycle stages and their
underlying processes itself shall be defined further in corresponding PSR.
4.2.4.2 Manufacturing
The inputs and outputs related to the following aspects shall be included in the manufacturing stage:
a) Production of the materials and components making up the reference product, including the final packaging
and technical documentation it is supplied with:
— Production (extraction, treatment, transformation, etc.) of raw materials necessary to manufacture the
components, including the flows associated with waste and discarded materials generated by the
manufacturing processes up to their end-of-waste status or disposal of final residues;
— Industrial transforming and manufacturing processes of the various parts, components, and products;
— Transportation of materials, components and subassemblies from the supplier’s production site to the
assembly site(s) and/or packaging site(s).
b) If applicable and relevant, production (extraction, treatment, transformation, transportation, etc.) of ancillary
materials used in manufacturing but not supplied with the final product.
c) Industrial processes used to assemble the reference product and packaging components;
d) Transportation of the packaged product from the packaging site to the manufacturer's last logistics platform.
4.2.4.3 Distribution
The inputs and outputs associated with the following aspects shall be included in the distribution stage:
a) Transportation of the product in its packaging from the manufacturer's last logistics platform to the distributor
and from the distributor to the place of installation and/or operation.
b) Processes, including the required materials and components, e.g. additional packing materials, needed for
the distribution and transportation of the product
c) In case of repacking, end-of-life management of generated waste (e.g. material recovery, energy recovery,
disposal).
4.2.4.4 Installation
This stage shall be considered separately only when a specific installation process is defined for the respective
product or corresponding regulatory requirements exist. This shall be defined in the PSR. If no PSR clearly
indicates how installation should be handled, but installation processes are relevant, the LCA practitioner shall
consider these and document it in the LCA report.
The inputs and outputs associated with the following aspects shall be included in the installation stage:
a) Processes, including the required materials and components, needed for installation, e.g. as specified by
the manufacturer and/or applicable regulations and standards
b) Management of the waste generated at the installation place (collection and treatment up to its final
treatment (e.g. material recovery, energy recovery, disposal):
— Packaging;
— Discarded installation materials;
— Waste associated with the installation processes.
If applicable, the processes, components and energy included in the installation stage shall be described and
justified in the LCA report.
4.2.4.5 Use
The inputs and outputs associated with the following aspects shall be included in the use stage:
a) Energy consumption and other flows (emissions, water, etc.) of the product during its use over the RSL;
b) Production, distribution, installation and end-of-life of elements required to operate, service and maintain
the reference product over the RSL.
Processes aiming at extending product lifetime such as repair, reuse, remanufacture shall be taken into account
in the use stage.
4.2.4.6 De-installation
This stage shall be considered separately only when a specific process is defined for the respective product or
corresponding regulatory requirements exist. This shall be defined in the PSR. If no PSR clearly indicates how
de-installation should be handled, but associated processes are relevant, the LCA practitioner may consider
these as part of the end-of-life stage. These assumptions shall be documented in the LCA report.
The inputs and outputs associated with the following aspects shall be included in the de-installation stage:
a) Processes needed for de-installation, e.g. as specified by the manufacturer and/or applicable regulations
and standards
b) Management of the waste generated at the de-installation place (collection and treatment up to its final
treatment (e.g. material recovery, energy recovery, disposal…):
— Discarded de-installation materials;
— Waste associated with the de-installation processes.
If applicable, the processes, components and energy included in the de-installation stage shall be described
and justified in the LCA report.
