Why wires and cables are BIS-regulated
Wires and cables sit directly in the electrical safety chain — a non-conforming cable is a fire and shock hazard, not just a quality issue. That's why cable and wire categories have long been part of BIS's compulsory ISI certification list, well ahead of many other product categories that have only recently come under similar schemes.
Which products are typically covered
Coverage spans common categories like PVC-insulated cables, industrial cables, and other electrical wiring products used in domestic, commercial, and industrial installations. Exact coverage and the applicable Indian Standard depend on the cable's construction, insulation type, and rated voltage, so classification is the necessary first step before anything else.
What testing typically evaluates
Cable testing generally assesses conductor resistance, insulation resistance, current-carrying capacity, and construction quality against the applicable standard. Because cables are used in fixed installations for years, standards for this category tend to weight durability and consistency heavily, not just a one-time pass/fail result.
The certification process
Cable certification follows the ISI licensing route: applicability and standard confirmation, documentation of your manufacturing process and in-house testing capability, sample testing at a BIS-recognised lab, factory inspection to verify your production quality control, and licence grant — followed by periodic surveillance testing to maintain the licence.
What manufacturers should prepare
Have your raw material sourcing and in-house testing records organised before applying — BIS inspectors will want to see consistent quality control on incoming materials, not just finished-product testing. If you manufacture multiple cable types or gauges, confirm which specific variants your licence needs to cover, since scope isn't always automatically broad across your full product range.
FAQs
Do all cable types need a separate BIS licence?
Coverage and licensing scope depend on the specific cable construction and standard — some licences cover a family of related products, others are narrower. We confirm scope against your specific product range before applying.
How often is a cable manufacturer's factory re-inspected?
ISI licences are subject to ongoing surveillance, including periodic inspections and market sample testing, to confirm continued conformance after the initial licence is granted.
