BS 6746:1990 — PVC insulation and sheath materials for electric cables

← Back to all standards

BS 6746 is the British Standard specification for PVC compounds used as electric cable insulation and sheathing. To match this to your program, talk with our team.

What BS 6746 Covers

It defines the classifications and material requirements for PVC cable compounds, including tensile properties verified before and after ageing.

How the Test Is Run

PVC compound specimens are cut to a dumbbell shape and pulled to failure, and tensile strength and elongation, before and after ageing, are checked against the requirements.

Why It Matters

Verified compound properties support safe, durable cable insulation; low-force grips and an extensometer suited to soft PVC are essential.
