BIS ISI Certification for PVC Insulated Cables

BIS ISI Certification for PVC Insulated Cables - IS 694:2010. PVC Insulated Cables are widely used in electrical installations across industries and homes due to their durability, flexibility, and resistance to heat, chemicals, and moisture. In India, the Bureau of Indian Standards (BIS) mandates certification for such products to ensure public safety and product reliability. If you're a manufacturer or importer of these cables, obtaining BIS ISI Mark Certification for PVC Insulated Cables is not just necessary but also a legal requirement. This article explains the entire process, benefits, requirements, testing, packaging, and documentation in detail.
What are PVC Insulated Cables?
PVC Insulated Cables refer to electrical wires insulated with Polyvinyl Chloride (PVC). These cables are valued for their excellent dielectric strength, flexibility, and resistance to chemicals, heat, and water. Unlike conventional wires, they do not emit toxic fumes and have low levels of lead and heavy metals, making them environment-friendly. In India, such cables must comply with the Indian Standard IS 694:2010, which governs single and multicore cords made of copper or aluminium conductors sheathed with PVC insulation for voltages up to 1100V.
Why is BIS ISI Certification for PVC Insulated Cables Mandatory?
The BIS Certification for PVC Insulated Cables is essential because it ensures that the product meets the safety, quality, and performance criteria set by the government. Selling PVC insulated cables without this certification is illegal and punishable by law. This certification is mandatory under the BIS Conformity Assessment Scheme, especially under the ISI mark scheme. The ISI Mark indicates that the product has been tested and conforms to Indian Standards.
Benefits of BIS Certification for PVC Insulated Cables
One of the main benefits of obtaining BIS ISI Certification for PVC Insulated Cables is legal compliance. According to Indian regulations, manufacturers cannot sell PVC insulated cables in the domestic market without BIS approval. Possessing a valid certificate allows the manufacturer to produce and sell the cables throughout the country without legal interruptions or the threat of penalties.
The ISI Mark is a symbol of trust and credibility. Products bearing the ISI mark assure consumers that they meet the highest safety and quality standards, thereby enhancing the brand’s image and reliability. Consumers are more likely to prefer certified products over non-certified alternatives.
Certified cables undergo rigorous testing and continuous monitoring by BIS, which ensures that each batch maintains the same quality level. This commitment to consistency builds a loyal customer base and leads to greater customer satisfaction.
Additionally, having BIS Certification boosts business competitiveness. In government tenders and bulk supply contracts, BIS-certified products are preferred or even mandatory. This opens up new business opportunities and increases the overall revenue potential of certified manufacturers.
Basic Requirements for ISI Certification for PVC Insulated Cables
To be eligible for the BIS ISI Certification for PVC Insulated Cables, a manufacturer must fulfill the following requirements:

The product must strictly meet the specifications outlined in IS 694:2010.

Only the original manufacturer of the finished product can apply. Distributors or retailers are not eligible.

The factory must have all the necessary machinery and in-house testing facilities in line with BIS norms.

If the manufacturer operates multiple factories at different locations, separate applications are required for each.

All manufacturing processes, including testing and packaging, must be carried out on-site. Any outsourcing must be pre-approved by BIS.

BIS also publishes Product Manuals which include specific testing protocols, equipment lists, and inspection guidelines. Manufacturers should consult these manuals before applying.
Types of Tests Conducted for BIS Certification for PVC Insulated Cables
To ensure the safety, durability, and functionality of the PVC insulated cables, BIS mandates a series of tests. Each of these tests has a specific purpose and collectively confirms that the cable meets Indian Standard specifications under IS 694:2010.

The Flammability Test is conducted to evaluate the cable’s ability to resist ignition and fire spread. It ensures that in case of electrical faults, the cable does not easily catch fire or spread flames, thereby enhancing safety in homes and industrial setups.

The Flex Test checks the cable's endurance when bent repeatedly. This is important for applications requiring frequent movement or where cables are installed in constrained spaces. A cable that fails this test may break or wear prematurely.

Wrapping Tests are done specifically on aluminium wires to determine the strength and flexibility of the outer wrapping. Weak wrapping can lead to breakage or exposure of the inner conductor.

The Heat Shock Test assesses the behavior of the insulation material when subjected to high temperatures. If the insulation cracks or melts under heat, it fails the test.

The Insulation Resistance Test measures the resistance offered by the insulation against electrical current. High resistance means better insulation and minimal chances of current leakage.

The High Voltage Test (HV) checks the insulation’s ability to withstand high voltages. The cable should not allow any breakdown or spark during this test.

Conductor Resistance Test determines the internal resistance of the conductor (copper or aluminium), which is critical for efficient current flow.

Oxygen Index Test and Smoke Density Rating evaluate the flame retardant and smoke emission characteristics of the cable. A higher oxygen index means more resistance to burning, and a lower smoke density ensures visibility and safety during fire accidents.

Other tests like Hot Deformation, Spark Test, Shrinkage Test, Annealing Test (for copper wires), and Tensile Test (for aluminium wires) are carried out to check mechanical strength, dimensional stability, and long-term performance.
All tests must be performed in a BIS-certified laboratory or in the manufacturer’s in-house lab equipped and staffed as per BIS requirements.
Packing and Labelling Requirements for PVC Insulated Cables
Manufacturers must comply with packing and labelling guidelines as per IS 694:2010. BIS assesses compliance with these norms during the factory inspection. The labelling must include the following details:

Brand name or trademark

Manufacturer’s name

Number of cores

Cable code

Conductor type (e.g., ATC for tinned copper)

Type of cable and voltage grade

Flame retardant specification (e.g., FR, FR-LSH)

Length of cable

Number of lengths (if more than one)

Direction of drum rotation (if packed on wooden drums)

Nominal cross-sectional area of conductor

Failure to adhere to proper labelling may result in rejection during the inspection or post-certification audits.
