Full title and description

St IEC TS 62271-320-2025 — High‑voltage switchgear and controlgear - Part 320: Environmental aspects and life cycle assessment rules for high‑voltage switchgear and controlgear. This Technical Specification gives guidance to suppliers, manufacturers, users and waste operators of high‑voltage switchgear and controlgear (rated >1 kV AC and >1.5 kV DC) and associated auxiliary equipment on environmentally conscious design, life cycle assessment (LCA) methods and communication of environmental information across the product life cycle.

Abstract

This Technical Specification defines environmental aspects and life cycle assessment rules tailored to high‑voltage switchgear and controlgear. It introduces life‑cycle thinking (design for environment), reference service life, LCA modelling rules and reporting practices to support comparability, procurement, end‑of‑life handling and regulatory or voluntary environmental declarations. The document is intended to help manufacturers and users quantify and communicate environmental impacts and to support environmentally conscious product design and decision making.

Scope

IEC TS 62271-320:2025 provides guidance on environmentally conscious design and on assessing environmental impacts of high‑voltage switchgear and controlgear and their assemblies (rated above 1 kV AC and 1.5 kV DC), together with associated auxiliary equipment. It specifies life cycle assessment rules, reference service life conventions, modelling and allocation rules, data reporting and communication practices intended to ensure consistent environmental information exchange between manufacturers, users, procurers and waste operators. The scope also covers classification, terms and definitions and normative references relevant to environmental assessment for the IEC 62271 series.

Key topics and requirements

• Life cycle thinking and environmentally conscious design principles for HV switchgear and controlgear (design, material selection, energy use, end‑of‑life considerations).
• Rules and methodological choices for life cycle assessment (goal and scope definition, system boundaries, functional unit, reference service life, allocation and cut‑off rules).
• Classification and description of switchgear, switching devices and assemblies for consistent LCA modelling.
• Normative references and alignment with other IEC 62271 parts (for example IEC 62271‑1 and IEC 62271‑4) for handling gases and common specifications.
• Reporting and communication requirements for environmental information across the supply chain (data exchange, environmental declarations, use‑phase and end‑of‑life information).
• Guidance for manufacturers, users and waste operators on minimising environmental impacts and complying with regulatory or voluntary environmental programmes.

Typical use and users

Primary users include manufacturers of high‑voltage switchgear and controlgear, product designers and R&D teams, environmental/Sustainability or compliance managers, procurement and specification engineers, testing and certification bodies, system integrators, asset owners/operators and waste management or recycling organisations. The TS is used to develop product‑level LCA studies, create environmental product declarations (EPDs) or supplier environmental information, and to inform greener product design and procurement decisions.

Related standards

Key related publications and series references include the IEC 62271 family (notably IEC 62271‑1: Common specifications for AC switchgear and controlgear) and IEC 62271‑4 (handling procedures for gases for insulation and/or switching). The Technical Specification also references general LCA and environmental standards (ISO 14040/14044 family) and other IEC normative references as applicable for the 62271 series.
