This document specifies the dimensions and requirements for unscreened single twisted pair RF cables with a specified analogue bandwidth up to 1 GHz intended for use in road vehicle applications where the nominal system voltage is 30 V a.c. or 60 V d.c. This edition is a successor standard to ISO 6722-1, ISO 6722-2, and ISO 14572.

Abstract

Overview

ISO 19642-12:2023 specifies dimensions and performance requirements for unscreened single twisted-pair RF (UTP / JUTP) cables for road-vehicle applications with a specified analogue bandwidth up to 1 GHz. The standard targets cables intended for vehicle electrical systems with nominal voltages of 30 V a.c. or 60 V d.c. and defines test methods, construction features and pass/fail criteria applicable to in-vehicle RF signal links.

Key topics and technical requirements

This part of the ISO 19642 series covers:

Scope and general conditions
- Intended use in road vehicles, nominal system voltage limits and general test conditions.
Cable construction and designators
- Requirements for cores, twisted-pair geometry, optional separator and outer sheath.
Dimensional requirements
- Outside diameter, insulation thickness, conductor diameter, CSA, lay length and ovality criteria.
Electrical requirements and RF performance
- Low‑frequency electrical tests (conductor resistance, continuity, insulation resistivity, withstand voltage).
- RF tests including characteristic impedance (frequency and time domain), insertion loss (IL), return loss (RL), velocity of propagation and unbalance attenuations.
Mechanical tests
- Strip force, break force, cyclic/dynamic bending, minimum bending radius, abrasion and flexibility tests.
Environmental tests
- Ageing (long term 3 000 h and short term 240 h at temperature class rating), thermal overload, pressure tests, shrinkage, cold impact, humidity cycling, resistance to water, chemicals, ozone, flame propagation and durability of markings.
Representative element testing
- Procedures to select representative cable elements for testing and reference test setups.

Practical applications
