Full title and description

Road vehicles — Automotive cables — Part 3: Dimensions and requirements for 30 V a.c. or 60 V d.c. single core copper conductor cables. This International Standard specifies dimensions and basic requirements for single‑core copper conductor cables intended for general‑purpose vehicle applications where the nominal system voltage is ≤ 30 V a.c. or ≤ 60 V d.c.; it also applies to individual cores in multi‑core cables.

Abstract

The document defines size, constructional and performance requirements for single‑core copper conductor cables used in road vehicles operating at the stated low‑voltage systems. It focuses on conductor construction, nominal cross‑sectional areas and dimensional limits, and on general electrical and mechanical requirements applicable to these cable cores.

Scope

This part of ISO 19642 specifies the dimensions and requirements for single‑core copper conductor cables for general vehicle applications where the nominal system voltage is less than or equal to 30 V a.c. or less than or equal to 60 V d.c. The requirements are applicable to individual cores within multi‑core cables as well as to free single‑core cables. It is limited to copper conductors and addresses dimensional, constructional and basic performance characteristics suitable for low‑voltage automotive systems.

Key topics and requirements

• Dimensional requirements: nominal conductor cross‑sectional areas, conductor diameters and tolerances for single‑core copper cables.
• Conductor construction: acceptable copper conductor types and constructions (stranded/solid) for the specified cross sections.
• Insulation and identification: requirements for insulation thickness, core identification and marking where applicable.
• Electrical characteristics: rated voltage limits (≤ 30 V a.c. or ≤ 60 V d.c.), conductor resistance requirements and related electrical performance expectations.
• Mechanical characteristics: basic mechanical properties and limits relevant to automotive installation and service conditions.
• Applicability: individual cores of multi‑core cables are covered in the same manner as separate single‑core products.

Typical use and users

Used by automotive OEMs and suppliers, cable and wiring-harness manufacturers, design engineers, component testers and conformity assessment laboratories. Typical applications include vehicle internal wiring for auxiliary systems, low‑voltage circuits, harness cores and any situation requiring single‑core copper cables suitable for ≤ 30 V a.c. / ≤ 60 V d.c. vehicle networks.

Q: What does it cover?

A: It covers dimensional limits, conductor construction (copper), basic electrical and mechanical expectations, and the application of those requirements to individual cores in multi‑core cables intended for low‑voltage vehicle systems.

Q: Who typically uses it?

A: Automotive OEMs, wiring‑harness and cable manufacturers, electrical design engineers, and test/conformity laboratories use this standard to ensure compatibility and minimum performance for single‑core vehicle cables.

Q: Is it current or superseded?

A: ISO 19642‑3:2019 is published and remains an active part of the ISO 19642 series; ISO has an approved work item (ISO/AWI 19642‑3) to revise or replace Part 3, so users should monitor ISO announcements for a future updated edition.
