Overview
IEC PAS 63629:2025 - PSR – Specific rules for luminaires provides Product Specific Rules (PSR) to guide manufacturers and LCA practitioners in preparing Product Environmental Profiles (PEP) and Type III Environmental Declarations (EPD) for luminaires. Published as a Publicly Available Specification by IEC and based on the PEP ecopassport® PSR0014, this document standardizes how lighting products are described and assessed from an environmental and life‑cycle perspective.
Key topics and requirements
- Scope and applicability
- Applies to luminaires intended to be connected to the power grid (replaceable or non‑replaceable light sources).
- Excludes self‑contained emergency electrical equipment (covered by separate PSR).
- Product Environmental Profile (PEP) requirements
- Defines product specifications to be adopted by manufacturers when developing PEPs under the PEP ecopassport® program.
- Ensures PEPs provide verifiable, comparable and non‑misleading environmental information.
- Life Cycle Assessment (LCA) rules
- Specifies the functional unit and reference flow, system boundaries, cut‑off criteria and allocation rules required for LCA of luminaires.
- Requires declaration of conventional typical lifetime used for LCA calculations.
- Sets default use scenarios and guidance for the product use stage (power consumption, operating hours, and application type considerations).
- Data and reporting
- Defines environmental data requirements, impacts calculation methodologies, and formatting for PEPs.
- Includes rules for extrapolation to homogeneous product families and for joint environmental declarations.
- Governance and review
- Developed in alignment with ISO/IEC Directives and subjected to third‑party critical review; PAS status intended as interim guidance until full international PSR standards are published.
Applications and users
This PSR is practical for:
- Manufacturers of luminaires preparing or updating Product Environmental Profiles (PEP) and EPDs.
- LCA experts and environmental managers who need consistent rules for LCA modelling and reporting for lighting products.
- Third‑party verifiers and certification bodies assessing conformity of luminaire environmental declarations.
- Specifiers, buyers and sustainability professionals who compare environmental performance of lighting systems across markets.
