GB/T 2951 — Test Methods for Cable Insulation and Sheath Materials

← Back to all standards

GB/T 2951 is the Chinese national standard series defining common test methods for polymeric insulating and sheathing materials of electric and optical cables. To match this to your program, talk with our team.

What GB/T 2951 Covers

It covers the mechanical and physical tests, including tensile before and after ageing, used to verify cable insulation and sheathing compounds.

How the Test Is Run

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 polymer are essential.
