CLC/TC 22X/WG 09 - Material Efficiency for Circular Economy

This document defines product specific rules (PSR) for the development of environmental product declarations (EPD) and/or Carbon Footprint of Products (CFP) for power electronic converter systems (PECS) and equipment. It specifies the process and requirements on how to conduct life cycle assessment (LCA) in the context of EPD or CFP for the following types of PECS: — adjustable speed electrical power drive systems (PDS) as defined in the EN IEC 61800 series; — uninterruptible power systems (UPS) as defined in the EN IEC 62040 series; — static transfer systems (STS) as defined in the EN IEC 62310 series; — power supply units (PSU) as defined in the EN IEC 60204 series; — central safety power supply systems (CPS) as defined in EN 50171; — bi-directional grid-connected power converters (GCPC) as defined in the EN IEC 62909 series. High voltage direct current (HVDC) equipment and other PECS (e.g. photovoltaic, wind turbines or e-vehicles) for which other dedicated product committees and specific standards exist are excluded from the scope. This document defines functional units and default scenarios in the product-specific context and common rules and guidelines for: a) the life cycle assessment (LCA), including the requirements for default scenarios; b) the Material Efficiency Assessment, including the requirements for default scenarios; c) the LCA report and Environmental Product Declaration (EPD). The LCA principles and framework are based on EN ISO 14040 and EN ISO 14044 and are therefore out of the scope of this document. In addition, this document defines specific Ecodesign assessment methods and specifications for the material efficiency aspects of PECS and equipment that are derived from published horizontal and generic standards for energy-related products (EN 45550 to EN 45559 series). This document specifies these generic standards in PECS context further through assessment requirements and default scenarios to support ecodesign and related customer information. Further, this includes definitions and specifications to enable material efficiency assessments at system level of PECS. It provides consistent and common criteria for considering material efficiency-related data to be operated by stakeholders along the lifecycle, supporting the building of digital product passport (DPP), data migration and interoperability of products and systems, including digital twins.
