European foreword
This document (CLC/TR 50674:2018) has been prepared by WG16 "Uncertainty" of CLC/TC 59X
"Performance of household and similar electrical appliances".
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.
This document is primarily for information. However, the reader should note that this Technical Report
also includes some statements based directly on European eco-design and energy labelling regulations
which are applicable for certain types of product at the time of writing.
This Technical Report has been developed from early experience of energy label and eco-design
verification projects. It also draws on the experience of pilot projects such as the ATLETE (Appliance
Testing for Energy Label and Evaluation) which were co-funded by the Intelligence Energy Europe
Programme of the European Union. Two projects were carried out under this scheme: refrigerators
(2009 to 2011) and washing machines (2012 to 2014). The projects were used to: check compliance
with energy labelling and ecodesign regulations for these appliance types across the EU; improve the
capacity of testing laboratories; and support cooperation among national Market Surveillance
Authorities (MSAs) by demonstrating how verification projects could be undertaken.
Introduction
The European energy labelling scheme (and associated eco-design requirements) relies on
performance declarations being made accurately by the suppliers of the labelled products. To ensure
the integrity of the labelling scheme and to prevent abuse through overstated claims, it is a requirement
of the regulations that the scheme is policed by the member states. Policing is conducted by MSAs.
One of the more significant tools of the MSAs is the verification of energy label and eco-design claims.
Energy labelling and eco-design regulations identify the specific claims that can be verified and the
verification tolerances that should be applied. This Technical Report describes how a typical verification
project can be carried out and gives specific detail on the subjects of model selection, laboratory
selection and carrying out the testing procedure in two steps.
The objective of verification testing is to come to a clear and legally sound decision as to whether a
product complies with the requirements given in a Regulation or if the declarations made by the supplier
are incorrect.
This Technical Report is intended to be a supporting tool valid at EU/EEA level and Country level for
MSAs dealing with compliance and verification issues. It aims to help optimize the available resources
and increase the effectiveness of MSAs engaging in the verification process.
1 Scope
This Technical Report provides guidance for the verification testing of household and similar electrical
appliances according to the Commission Regulations implementing Ecodesign Directive 2009/125/EC
and Commission Delegated Regulations supplementing Energy Labelling Directive 2010/30/EU. It is
also due to be suitable for succeeding documents.
This Technical Report might also be applicable to other types of energy related product and parts of it
might also be applicable for the verification of product claims in schemes outside the European Union.
