Full title and description

IEC 63366:2025 — Product category rules for life cycle assessment of electrical and electronic products and systems. This horizontal PCR (product category rules) document defines the process and requirements for conducting life cycle assessment (LCA) and producing Type III environmental declarations (environmental product declarations / EPDs) specifically for electrical and electronic products and systems (EEPS).

Abstract

IEC 63366:2025 provides common rules for LCA applied to EEPS, including requirements for developing default scenarios, preparing the LCA report, and the development of product‑specific rules (PSR). It gives additional guidance for environmental declarations while relying on the LCA principles and framework of ISO 14040 and ISO 14044. The standard is intended as a horizontal starting point for product committees; PSR developed by product committees take precedence over this generic PCR.

General information

• Publication date: 6 June 2025 (valid from 06.06.2025).
• Publisher: International Electrotechnical Commission (IEC).
• ICS / categories: 13.020.01 — Environment and environmental protection (general).
• Edition / version: Edition 1.0 (first edition, 2025).
• Number of pages: 118 pages (IEC bilingual English/French publication).

Scope

IEC 63366:2025 specifies product category rules (PCR) applicable to electrical and electronic products and systems (EEPS) to support the development of Type III environmental declarations (EPDs). The scope covers: requirements and processes for performing LCAs in the EEPS context; guidance for establishing default scenarios where appropriate; content and structure of the LCA report; and procedures for developing PSR. The document is a horizontal publication under IEC Guide 108 and is intended to be complemented by product‑specific PSR developed by relevant technical committees.

Key topics and requirements

• Definition and structure of product category rules (PCR) for EEPS LCAs.
• Requirements for carrying out life cycle assessment (goal & scope, inventory, impact assessment) in line with ISO 14040 / ISO 14044 principles (these ISO standards are normative references for LCA methodology).
• Guidance and mandatory elements for developing default scenarios and assumptions when product‑specific data are unavailable.
• Content and reporting requirements for the LCA report and for Type III environmental declarations (EPDs) for EEPS.
• Procedures and recommendations for producing product‑specific rules (PSR) within product committees; PSR take precedence over this horizontal PCR.
• Status as an essential horizontal publication (IEC Guide 108) intended to harmonize PCR development across product committees.

Typical use and users

Primary users include manufacturers of electrical and electronic products, LCA practitioners preparing Type III environmental declarations (EPDs), product‑committee experts developing PSR, ecolabel/EPD programme operators, sustainability and compliance teams, and regulators or purchasers seeking harmonized environmental information for EEPS. The standard is used both as a direct PCR where no PSR exists and as a baseline for developing product‑specific PCRs.

Related standards

Key related documents and references include ISO 14040 and ISO 14044 (LCA principles and requirements), IEC Guide 108 (use and status of horizontal publications), and regional/adopted versions such as EN IEC 63366 / national adoptions (e.g., SS-EN IEC 63366). IEC 63366:2025 is intended to work alongside product‑specific rules and may replace or be used together with earlier EEPS PCRs or national variations (for example where SS-EN 50693 and other existing instruments are in scope for transition).

FAQ

Q: What is this standard?

A: IEC 63366:2025 is a horizontal product category rules (PCR) standard specifying how to perform life cycle assessment (LCA) and prepare Type III environmental declarations for electrical and electronic products and systems. It establishes common rules and reporting requirements for EEPS LCAs.

Q: What does it cover?

A: It covers the PCR framework for EEPS LCAs, requirements for default scenarios, content of the LCA report, and guidance for developing product‑specific rules (PSR). It does not replace ISO 14040 / ISO 14044 but builds on those LCA principles.

Q: Who typically uses it?

A: Manufacturers, LCA consultants, EPD programme operators, product committee experts drafting PSR, sustainability teams, and procurement/regulatory bodies use the standard to create or evaluate harmonized EPDs for electrical and electronic products.

Q: Is it current or superseded?

A: IEC 63366:2025 is the current, first edition published in 2025. It is a new horizontal PCR; product committees may publish PSR that supplement or take precedence over its requirements for specific product groups.

Q: Is it part of a series?

A: It is a horizontal IEC PCR intended to be used together with product‑specific rules (PSR). It may also be adopted regionally as EN IEC 63366 and national equivalents; product committees will issue PSR documents that form the series of product‑specific applications.

Q: What are the key keywords?

A: Product category rules (PCR), life cycle assessment (LCA), environmental product declaration (EPD), Type III declaration, electrical and electronic products and systems (EEPS), product‑specific rules (PSR), ISO 14040, ISO 14044.
