IEC TR 62839-1:2014 โ Environmental Declarations for Wires, Cables and Accessories
🌎 Key Insight: IEC TR 62839-1 establishes the first harmonized Product Specific Rules (PSR) for environmental declarations of communication and control cables, enabling consistent, comparable Product Environmental Profiles (PEP) across the global cable industry.
1. Scope and Framework
IEC TR 62839-1:2014 is a Technical Report that specifies Product Specific Rules (PSR) for wires and cables used in communication, data, control and command applications. It provides methodological precision for developing Product Environmental Profiles (PEP) and Product Category Rules (PCR) according to the ISO 14020 series of environmental labelling standards.
The document covers three categories of products: communication and data wires and cables (both metallic and optical fibre), control and command wires and cables, and accessories (the latter being for further study). It is primarily intended for environment and product managers, LCA experts, and verifiers responsible for PEP/PCR conformity assessment.
⚠️ Scope Limitation: This Technical Report deals exclusively with “wires and cables” products. Accessory products are marked “for further study” (FFS) and are not yet covered by specific rules. Users developing PEP for complete systems including accessories should clearly state this boundary limitation.
2. System Boundaries and Life Cycle Phases
The standard defines five distinct life cycle phases that must be recorded in the environmental declaration:
| Life Cycle Phase | Boundary Scope | Key Considerations |
|---|---|---|
| Manufacturing | From raw material extraction to product at producer’s last logistics platform | Material composition, energy consumption, production waste, packaging |
| Distribution | From producer logistics platform to installation site | Transport distance, mode of transport, fuel type |
| Installation | To be determined by user (excluded from PEP/PCR perimeter) | Site-specific, highly variable, not standardized |
| Use | Product operation, maintenance, and service life | Power consumption (if applicable), lifetime, use rate |
| End of Life | Transportation to treatment centre or landfill | Recycling potential, material recovery, disposal route |
✅ Engineering Insight: The exclusion of the installation phase from the PEP/PCR perimeter is a practical recognition of the wide variability in cable installation methods. However, PEP users should evaluate installation impacts separately in their specific use context to obtain a complete environmental picture.
3. Communication and Data Cables — Detailed Requirements
3.1 Functional Unit and Reference Flow
For communication and data cables, the functional unit is defined as: “Transmit a communication signal on 1 m according to XX protocol, YY category, during X years and a Y% use rate in accordance with the standards in force.” This standardized definition ensures that environmental declarations from different manufacturers are directly comparable.
3.2 Twisted Pair, Coaxial and Optical Fibre Cables
The standard recognizes three distinct transmission media types, each with different environmental impact profiles:
| Parameter | Twisted Pair (Category 5e/6/7) | Coaxial Cable | Optical Fibre Cable |
|---|---|---|---|
| Typical lifetime | 10-15 years | 10-20 years | 15-25 years |
| Use rate | 30-50% | 50-80% | 30-50% |
| Main material impact | Copper conductor, PE insulation | Copper conductor, Al shield, PE jacket | Glass fibre, polymer coatings, steel strength members |
| Recycling potential | High (copper recovery) | Medium-High | Medium (glass and polymer separation) |
| Reference standard | IEC 61156 series | IEC 60794 series (RF cables) | IEC 60793 and IEC 60794 series |
4. Implementation Guidance for LCA Practitioners
The standard provides important methodological precisions for conducting Life Cycle Assessments of cable products. Key technical aspects include:
- Use phase modelling: For passive cables (non-powered), the use phase environmental impact may be zero if no power is consumed. However, for active cables (with signal amplification or conditioning), the power consumption during use must be included in the assessment.
- Lifetime and use rate: These parameters are critical determinants of overall environmental impact. The standard provides default values linked to application types defined in Annex A (Table A.1). For example, building backbone cabling typically has a longer lifetime than patch cords.
- End-of-life scenarios: Manufacturers must define the end-of-life scenario based on the product composition and available recycling infrastructure. Copper recovery from communication cables typically achieves over 90% material recovery in developed markets.
🔴 Critical Caution: When comparing PEP declarations from different manufacturers, ensure that the functional unit, system boundaries, and lifetime assumptions are aligned. A cable declared with a 20-year lifetime will show lower annualized environmental impact than an identical cable declared with a 10-year lifetime, even though the manufacturing impact is identical. Always normalize to the functional unit for fair comparison.
5. Frequently Asked Questions
Q1: Is IEC TR 62839-1 mandatory for all cable environmental declarations?
No, it is a Technical Report providing guidance rather than requirements. However, many PEP/PCR programmes reference this document as the normative basis for cable product declarations. For example, the PEP Ecopassport programme aligns closely with the rules defined in IEC TR 62839-1.
Q2: Does this standard cover power cables?
No, IEC TR 62839-1 specifically covers communication, data, control and command cables. Power cables (for energy transmission and distribution) are covered by other standards in the IEC 62839 series and related PCR documents.
Q3: How should recycling content be reported in a PEP?
The standard does not prescribe a specific method for recycling content. However, following ISO 14040/14044 guidelines, the recycled content should be declared separately, distinguishing between pre-consumer and post-consumer recycled material. Mass balance allocation is the commonly accepted approach.
Q4: Can a PEP be developed for a cable assembly (with connectors) using this standard?
This is a borderline case. The standard covers “wires and cables” but accessories are listed as “for further study.” For cable assemblies, the general PEP/PCR rules should be applied, with the cable portion following IEC TR 62839-1. The environmental impact of connectors should be assessed separately using applicable general rules.
