Overview
IEC TR 62422:2007 - "Environmental characterization of solid insulating materials" provides a framework for collecting and reporting environmental data on solid insulating materials used in electrotechnical products. The technical report guides suppliers, designers and engineers on a common format for environmental data reporting so that producers and product teams can evaluate potential environmental impacts of insulating materials across their life cycle. The methodology aligns with Life Cycle Assessment (LCA) principles (ISO 14040) and supports quick assessments and regulatory conformity checks.
Key Topics and Requirements
- Methodological framework: Life Cycle Thinking (LCT) approach based on LCA phases - goal & scope, inventory (LCI), impact assessment and interpretation.
- Goal and scope definition: Requires clear description of study background, object and functional unit (the electrotechnical product including selected insulating materials).
- System boundaries & allocation: Guidance on defining cut-offs and allocation rules for multi-output processes.
- Data quality: Requirements and recommendations for data quality to ensure comparability and usefulness.
- Life-Cycle Inventory (LCI): Collection of relevant inputs/outputs for production, use and end-of-life stages.
- Impact assessment & interpretation: Guidance on translating inventory data into potential environmental impacts.
- Material Category Requirements (MCR): Defines categories and specific environmental data needs for material types (see Annex A examples).
- Material Environmental Information Data Sheet (MEIDS): Standardized reporting format covering:
- Resource use (materials, energy)
- Pollutant emissions (expressed as potential environmental impact)
- Waste generation and end-of-life indicators (recyclability, recovery)
- Additional information such as processing hazards or disposal cautions (see Annex B example)
Applications and Who Uses It
- Product designers and electrical engineers - to compare insulating materials and make environmentally informed material choices during design.
- Materials suppliers and manufacturers - to prepare standardized MEIDS and supply consistent environmental data to customers.
- LCA practitioners and environmental managers - to incorporate insulating material data into broader product LCAs or environmental declarations.
- Regulatory and compliance teams - for quick assessment of conformity with product-related environmental regulations.
- Recycling and end-of-life planners - to evaluate recyclability, recoverability and safe disposal practices.
Related Standards

- ISO 14020 (Environmental labels and declarations) - referenced for reporting principles.
- IEC Guide 109 - referenced for recyclability definitions.
IEC TR 62422 supports consistent, comparable environmental data for solid insulating materials - enabling better material selection, more reliable LCA inputs, and clearer supplier–manufacturer communication.
