JWG 1 - TC 46/JWG 1

IEC TR 62839-1:2025 describes the product specific rules (PSR) for wires and cables used for communication, data, control and command.
These PSR are applicable in case the life cycle assessment (LCA) results are intended to be used in external communication in the form of an environmental product declaration (EPD), as laid out in ISO 14021, ISO 14025, ISO 14026 and ISO 14067. These PSR are complementary to the product category rules (PCR) for (LCA) of electrical and electronic products and systems (EEPS) provided in IEC 63366.
The following categories of wires and cables are covered in this document:
– communication and data wires and cables which can comprise metallic conductors or optical fibre;
– control and command wires and cables which can comprise metallic conductors or optical fibre.
This document is applicable to communication cables in general, it is related in particular to the wire and cable products covered by generic cabling described in the ISO/IEC 11801 series which is based on component standards described in the IEC 60794 series (fibre optic cables), IEC 61156 series (metallic balanced communication cables) and the IEC 61196 series (coaxial metallic communication cables). According to this relationship, this document is related to ISO/IEC 14763-5 which describes sustainability aspect of generic cabling.
This document is primarily intended for:
– environment and/or product managers;
– LCA experts in companies or contractors and other 3rd party operators, in charge of EPD;
– verifiers in charge of conformity assessment in accordance with the defined rules.
This second edition cancels and replaces the first edition published in 2014. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) The term "accessory products" has been removed from the title and the text as accessories are covered by IEC TR 62839-2.
b) The consideration of remote powering was added for the evaluation of the use stage.
c) Guidance was added with respect to evaluate the use stage of certain coaxial cables.
d) Update of the entire document to reflect a complete life cycle assessment.

IEC TR 62839-1:2014(E) specifies the PSR (product specific rules) for wires and cables used for communication, data, control and command. This PSR covers the use, installation and end-of-life stages and provides methodological precisions to PEP/PCR writing for "wires and cables and accessories products used for communication, data, control and command. PSR and general rules all together form the product category rules. Three categories of wires and cables are covered:
- communication and data wires and cables, which may have metal or optical fiber conductors;
- control and command wires and cables, which can have metal or fiber optical conductors;
- accessories.
This document only deals with the "wires and cables" products. "Accessories products are for further study. This document is primarily intended for:
- environment and/or product managers;
- LCA (life cycle assessment) experts in companies, in charge of PEP/PCR development;
- verifiers in charge of PEP/PCR conformity assessment in accordance with the defined rules.
