Full title and description

Road vehicles — Automotive cables — Part 4: Dimensions and requirements for 30 V a.c. and 60 V d.c. single core aluminium conductor cables. This International Standard specifies dimensions and technical requirements for single‑core aluminium conductor cables intended for general purpose vehicle applications with nominal system voltages ≤ 30 V a.c. or ≤ 60 V d.c.; the requirements also apply to individual cores in multi‑core cables.

Abstract

The document defines conductor and overall cable dimensional classes, conductor material and construction requirements (aluminium), insulation and sheath characteristics, identification/marking and reference test/inspection requirements. It is intended to ensure interchangeability and minimum performance for single‑core aluminium automotive cables used on low‑voltage vehicle electrical systems. Test methods referenced in this part are taken from the ISO 19642 series.

Scope

This standard applies to single‑core aluminium conductor cables and to individual cores in multi‑core cables intended for use in road vehicles where the nominal system voltage is ≤ 30 V a.c. or ≤ 60 V d.c. It specifies permissible dimensions, conductor construction and materials (aluminium), insulation/sleeving requirements, marking/identification and references the relevant test methods from the ISO 19642 series.

Key topics and requirements

• Conductor material and construction: aluminium conductor classes and acceptable constructions for automotive single‑core cables.
• Dimensional specifications: conductor cross‑sectional areas, nominal overall diameters and tolerance classes for interchangeability.
• Insulation and sheath requirements: minimum insulation thickness classes, material performance for automotive environments.
• Marking and identification: core marking, voltage rating identification and basic labelling requirements for traceability.
• Electrical requirements: conductor resistance/continuity characteristics and basic electrical performance limits appropriate for the nominal voltages.
• Reference test methods: mechanical, environmental and electrical tests are referenced to the ISO 19642 test methods part of the series.
• Applicability: covers individual cores in multi‑core assemblies as well as single‑core cables intended for general vehicle wiring harness use.

Typical use and users

Used by automotive electrical engineers, cable designers and manufacturers, vehicle wiring harness suppliers, component specification teams and quality/test laboratories. Typical applications include vehicle low‑voltage wiring harnesses, battery‑to‑vehicle electrical connections (low‑voltage circuits), and any vehicle system where aluminium single‑core cables are specified for ≤ 30 V a.c. or ≤ 60 V d.c. systems. Test labs and procurement teams use the standard to verify dimensional and basic performance compliance.

Related standards

ISO 19642 is a multipart series. Relevant related parts and documents include: ISO 19642‑1 (vocabulary and design guidelines referenced throughout the series), ISO 19642‑2 (test methods — note: part 2 has been revised in 2023 and newer editions of test methods should be checked when testing), ISO 19642‑3 (requirements for copper conductor single‑core cables), ISO 19642‑9/10 and other parts covering higher voltages and battery cable classes. The ISO catalogue entry for 19642‑4 also indicates an approved work item (ISO/AWI 19642‑4) in the ISO lifecycle. When implementing tests or purchasing test report forms, consult the current part‑2 test methods and any national adoptions.

FAQ

Q: What is this standard?

A: ISO 19642‑4:2019 is an ISO International Standard that specifies dimensions and minimum technical requirements for single‑core aluminium conductor cables intended for road vehicle applications with nominal system voltages up to 30 V a.c. or 60 V d.c.

Q: What does it cover?

A: It covers conductor construction and material (aluminium), dimensional classes (conductor and overall cable), insulation and sheath requirements, marking/identification and references to the series’ test methods used to verify cable performance; it also applies to individual cores in multi‑core cables.

Q: Who typically uses it?

A: Cable and harness designers, cable manufacturers, automotive OEM and supplier procurement/specification teams, and test/quality laboratories that verify cable dimensions and basic electrical/mechanical performance for low‑voltage vehicle wiring.

Q: Is it current or superseded?

A: ISO 19642‑4:2019 is published (2019 edition). ISO catalogue lifecycle information shows the series is under ongoing maintenance and certain parts of the series have been revised (for example ISO 19642‑2 test methods was updated in 2023); the ISO entry for part 4 indicates an approved work item (ISO/AWI 19642‑4) in the programme (i.e., the series is being actively maintained/reviewed). Users should confirm there is no newer edition or national adoption affecting their requirements before procurement or testing.

Q: Is it part of a series?

A: Yes — ISO 19642 is a multipart standard for automotive cables (vocabulary/design, test methods, copper and aluminium conductor parts, higher‑voltage parts and battery cable parts). Consult the ISO 19642 index and the individual part entries for related requirements and current editions.

Q: What are the key keywords?

A: aluminium conductor, single‑core, automotive cable, dimensions, low‑voltage, 30 V a.c., 60 V d.c., insulation, ISO 19642.
