109 Introduction
110 This document has been drafted under a CLC/TC 22X Committee initiative in the context of growing concerns
111 in the global and European regulatory and standardization activities that are currently in process.
112 Based on a NWIP prepared by the TC22X WG9 under the CENELEC Project reference PR = 73372: “Ecodesign
113 for power electronics including approach for environmental product declarations and specifications for the
114 material efficiency assessment”, the CLC/TC 22X Secretariat has prepared a Program of Work Item (PWI) that
115 has been registered under the CENELEC Project reference PR = 78985: “Ecodesign for power electronics
116 including approach for environmental product declarations and specifications for the material efficiency
117 assessment”.
118 Under the NWIP a call for Convenor and experts has been circulated for building the Committee team CLC/TC
119 22X/WG 9 “Material Efficiency for Circular Economy”. Based on a CLC/TC 22X/WG 9 decision, the PWI
120 standardization work started end of 2023. The CLC/TC22X Working Group 9 is the standardization working
121 group for drafting this prEN 50743 under CENELEC project 78985, based on the already published homegrown
122 standard EN 50598-3:2013. This EN has not been prepared as the reply to a European Commission (EC)
123 Standardization Request (SReq). But if agreed, it should become a standard supporting the EC Ecodesign for
124 Sustainable Product Regulation (ESPR): (EU) 2024/1781 for which no Regulation Delegated Acts or SReq have
125 been published yet for products and systems in the scope of the CLC/TC 22X Committee. The Power Electronics
126 Converter Systems (PECS) in the focus for this document are mainly VSDs (BDM, CDM), UPS, or GCPCs (see
127 scope definition for the complete list).
128 This project is clearly a European Economic Area (EEA) topic due to its connection to the current EC Ecodesign
129 Directive: 2009/125/EC, to the recently published EC Ecodesign for Sustainable Product Regulation (ESPR):
130 (EU) 2024/1781, and the EU Circular Economy Action Plan [6]. But, in a second step, in case of global interest
131 and depending on international horizontal standards issued from IEC/TC 111 (Environmental aspect for EEE),
132 this document should be offered and maintained at the IEC level for possible global applicability. To facilitate
133 the future standard allocation to IEC from the CENELEC offer, an IEC/TC 22/AG 12 (Advisory Group 12) has
134 been set up for establishing a cooperation and information exchange, to receive advice, comments, proposals
135 from non-European experts focusing on this CLC/TC 22X Committee project.
136 For the relationship with EU Legislation, an informative Annex ZZ will be drafted for giving the link between
137 clauses of this document and the future European Commission Delegated Act to be published under the ESPR
138 Regulation and possibly be adopted in early 2029.
139 This document provides a relevant, consistent, and harmonized approach for specifying substantiation and
140 respective requirements on the material efficiency aspects of Power Electronics Converter Systems (PECS) for
141 supporting life cycle assessment (LCA), using product-specific rules (PSR). It will also facilitate and harmonize
142 the way to prepare the Environmental Product Declarations (EPD). The use of this document should benefit
143 from the specification of durability, the ability to repair, reuse, upgrade, remanufacture, the recyclability,
144 recoverability, the proportion of re-used components or recycled material content, the declaration of Critical Raw
145 Material (CRM) as well as the information provided to the different stakeholders, including via the Digital Product
146 Passport (DPP).
147 This project does not intend to specify the Environmentally Conscious Design (ECD) of a PECS but should
148 focus on assessment and measurement as well as relevant information to be provided on material efficiency
149 aspects. It is a standardization work for preparing the adaptability and applicability of existing generic
150 approaches for such a PECS product-oriented standard. This document will support the necessary circularity
151 requested by the different scenarios of life cycle analysis (LCA), aiming for substantiating the quantitative green
152 claims provided by the European regulations, already published or still to come. For that purpose, in addition to
153 deriving and adapting the EN 4555x series for PECS, this document considers EN IEC 63366:2025 for the
154 benefit of the manufacturers dealing with their product LCA. This document should support the coming EC
155 Ecodesign for Sustainable Product Regulation (ESPR): (EU) 2024/1781 and related Delegated Acts to be
156 prepared for all categories of products and systems defined in its scope.
157 This document suggests common PSR for the Power Electronics Converter Systems that are in the scope of
158 the CLC/TC 22X Committee as much as possible. When particular PSR or other specific requirements can only
159 be related to a dedicated product or system (e.g. for Variable Speed Drives only or any other PECS within the
160 scope of this document) these particular PSR or other specific requirements for such products or systems will
161 be embedded in a dedicated normative annex of this document.
162 1 Scope
163 This document defines product specific rules (PSR) for power electronic converter systems (PECS) and
164 equipment. It specifies the process and requirements on how to conduct life cycle assessment (LCA) in the
165 context of environmental product declarations (EPD) for PECS in the field of:
166 — adjustable speed electrical power drive systems;
167 — adjustable speed electrical power drive systems (PDS);
168 — uninterruptible power systems (UPS);
169 — static transfer systems (STS);
170 — power supplies units (PSU);
171 — central safety power supply systems (CSPSS);
172 — bi-directional grid-connected power converters (GCPC).
173 High voltage direct current (HVDC) equipment and other PECS (e.g. photovoltaic, windmills or e-vehicles) for
174 which other dedicated product committees and specific standards exist are excluded from the scope.
175 This document defines functional units and default scenarios in the product-specific context and common rules
176 and guidelines for:
177 a) the life cycle assessment (LCA), including the requirements for default scenarios;
178 b) the Material Efficiency Assessment, including the requirements for default scenarios;
179 c) the LCA report and Environmental Product Declaration (EPD).
180 The LCA principles and framework are based on the ISO 1404x series (i.e. ISO 14040 and ISO 14044) and are
181 therefore out of the scope of this document.
182 In addition, this document defines specific Ecodesign assessment methods and specifications for the material
183 efficiency aspects of PECS and equipment that are derived from published horizontal and generic standards for
184 energy-related products (EN 45550 to EN 45559 series).
185 This document specifies these generic standards in PECS context further through assessment requirements
186 and default scenarios to support ecodesign and related customer information.
187 Further, this includes definitions and specifications to enable material efficiency assessments at system level of
188 PECS.
189 It provides consistent and common criteria for considering material efficiency-related data to be operated by
190 stakeholders along the lifecycle, supporting the building of digital product passport (DPP), data migration and
191 interoperability of products and systems, including digital twins.

437 ongoing reliability testing
438 ORT
439 testing of which the purpose is to ensure that no changes have occurred in components or production processes
440 that will have a systematic impact on reliability
441 Note 1 to entry: The methodology is like ALT, but the sample units are randomly selected from actual production. In the case
442 of drives, testing can be performed on drive modules, IGBT drive packages, PCB boards and even complete drives.
443 Depending on the risk level that has been set, samples are taken from production. If a failure occurs during testing, a
444 thorough root cause analysis is carried out to check whether the failure was a random event or due to a change in the
445 product or one of the components.
