BIS ISI Certification for Elastomer Insulated Cables - IS 9968 (Part 1): 2025

Elastomer-insulated cables are utilised in electrical applications where the cable requires reliable insulation, flexibility and the ability to withstand the operating environment. The quality of the conductors, the insulation and sheath will directly influence the safety and the service life of the completed cable.

In India, BIS ISI Certification for Elastomer Insulated Cables is mandatory compliance for manufacturers. The product has also been revised, and the current standard is IS 9968 (Part 1):2025. Elastomer Insulated Cables Specification Part 1: For Working Voltages up to and Including 1100 V, which is listed by BIS under Scheme-I (ISI Mark Scheme).

The old standard IS 9968 (Part 1):1988 was to be used concurrently with the new standard till 29 January 2026. Therefore, the manufacturers who are applying should make use of the existing requirements for 2025.

UMSPCS assists manufacturers with product assessment, Current Standard Review, Product Grouping, Laboratory Co-ordination, Technical Documentation, BIS Application Filing and Factory Inspection Preparation.

What Is IS 9968 (Part 1):2025 for Elastomer Insulated Cables?

IS 9968 (Part 1):2025 lays down the requirements for elastomer-insulated cables for working voltage of up to and including 1100 V.

Standard applies to constructions of cable and cord for fixed wiring, flexible cables and flexible cords. The updated version also includes further variants of rubber- and silicon-insulated and/or sheathed cables in the scope.

For certification purposes, the cable range has to be evaluated according to characteristics such as conductor material, conductor class, insulation, sheath, number of cores and conductor size.

Grouping guidance is provided in the BIS product manual to help establish the scope of a licence when considering these characteristics of products.
