IEC 60227-4:2024 details the particular specifications for light polyvinyl chloride sheathed cables of rated voltages of 300/500 V. This document provides the particular requirements for sheathed cables for fixed wiring which apply in addition to the appropriate requirements specified in IEC 60227-1, which apply to all cables. The tests for cables specified in the IEC 60227 series are described in IEC 63294.

Overview

IEC 60227-4:2024 - "Polyvinyl chloride insulated cables of rated voltages up to and including 450/750 V - Part 4: Sheathed cables for fixed wiring" specifies particular requirements for light PVC‑sheathed cables intended for fixed wiring with a rated voltage of 300/500 V. It is part of the IEC 60227 series and is to be used in conjunction with IEC 60227-1 (General requirements). Test methods for the series are referenced to IEC 63294.

Key topics and technical requirements

Scope and designation

Code designation: 60227 IEC 10.
Rated voltage: 300/500 V for sheathed cables for fixed wiring.

Construction requirements

Conductors: 2, 3, 4 or 5 conductors complying with IEC 60228 (class 1 for solid; class 2 for stranded).
Insulation: PVC compound type PVC/C around each conductor.
Inner covering: Extruded unvulcanized rubber or plastic covering over twisted cores; cores must be separable.
Sheath: PVC compound type PVC/ST4 applied over the inner covering; sheath must fit closely and be removable without damaging inner covering.

Dimensional and electrical data

Table 1 (in the standard) gives insulation and sheath thicknesses, mean overall diameter limits, and minimum insulation resistance for specified conductor cross‑sectional areas (examples included in the standard).

Tests and conformity

Compliance is verified by type tests (T) and sample tests (S) as listed in Table 2.
Normative test references include IEC 63294 (cable test methods), the IEC 60811 series (non‑metallic material tests), and IEC 60332‑1‑2 (vertical flame test).

Operational guidance

Temperature in normal use: 70 °C.
Guidance on safe use is provided via IEC 62440.

Applications and practical value

Intended use: fixed wiring applications where PVC‑sheathed cables up to 300/500 V are required - e.g., building wiring, lighting circuits and other installed power circuits within the rated voltage and temperature limits.

Practical benefits:

Ensures consistent mechanical, electrical, and fire‑performance properties.
Enables manufacturers to design and test cables to internationally recognized specifications.
Assists specifiers, procurement teams and regulators in selecting compliant PVC sheathed cables.
