Abstract

urn:iec:std:iec:62271::::This part of IEC 62271 provides guidance to suppliers, manufacturers, users, and waste operators of high-voltage switchgear and controlgear as well as their assemblies having a rated voltage above 1 kV AC and 1,5 kV DC, together with their associated auxiliary equipment, on environmentally conscious design, and on assessing environmental impacts when used in systems. This document also gives guidance on effective communication of environmental information throughout the entire life cycle.This document provides guidance on the process and general aspects to select UN sustainable development goals (UN sustainable development goals (SDG)), especially those dealing with health and environmental impacts and their assessments, represented respectively by:SDG 3-Good Health and Well-being;SDG 6-Clean Water and Sanitation;SDG 7-Affordable and Clean Energy;SDG 12-Responsible Consumption and Production;SDG 13-Climate Action;SDG 14-Life Below Water;SDG 15-Life on Land.This document gives guidance on the process and general aspects to implement environmentally conscious product design (ECD) principles, as given in urn:iec:std:iec:62430::::IEC 62430, essential for high-voltage electrical power equipment and power control equipment.This document gives guidance on executing the life cycle assessment (LCA) based on product category rules (PCR) in accordance with urn:iec:std:iec:63366::::IEC 63366, urn:iec:std:iso:14040::::ISO 14040 and urn:iec:std:iso:14044::::ISO 14044 and on applying the Type III environmental declaration in accordance with urn:iec:std:iso:14025::::ISO 14025, both for high-voltage switchgear and controlgear. This guidance provides standardized product specific rules (PSR) summarized as follows:Common rules for the LCA process describing functional units, system boundaries, life cycle inventory analysis, scenarios, environmental impact categories;Common rules for communicating information about the presence of regulated substances and the materials contained in the product, according to urn:iec:std:iec:62474::::IEC 62474;Common rules for communicating information about the end-of-life treatment of the product including material efficiency.This document does not address the environmental declaration programme, however it can be used by program operators.This document focuses on describing the LCA process referring to the functional unit, system boundary, scenarios, etc.Owing to variability of influencing factors, such as flows, allocations, not balanced and time-stable energy mix under different programmes, equipment customization, durability related to environmental conditions, it is not possible to compare two similar high-voltage switchgear and controlgear analysed in different contexts.This document does not address by-products from arcing which are generated in sufficiently small quantities such that their environmental impact can be neglected. Any by-product generated by arcing during the use of equipment is strongly dependent on operating conditions and cannot a priori be qualified nor quantified. However, they are not expected to be released in air and will be managed at end-of-life by a dedicated process.During the use of high-voltage switchgear and controlgear the handlings of normally arced gas are covered by urn:iec:std:iec:62271-4::::IEC 62271-4. When the volume of gaseous by-product is below 1 % of normally arced gas, it is not considered compared to the cut-off rules specified in this document. The scenarios related to the system boundary do not take into account leakages from failures except if an agreement is reached on this between user and manufacturer (see Table 7, item h).Power transformers, low-voltage switchgear and controlgear, and the interconnections with such equipment are not covered by this document. Therefore, assemblies according to urn:iec:std:iec:62271-202::::IEC 62271-202 or urn:iec:std:iec:62271-212::::IEC 62271-212 comprising any of the above equipment are not within the scope of this document.This document supports material efficiency for circular economy. However, one of the major issues related to remanufacturing is the consideration of used parts and product(s) while regulatory requirements are applicable to new product. For high voltage switchgear and controlgear and for this document remanufacturing is not considered avoiding any misalignment for life cycle assessment.
