BIS Certification for Cables for Motor Vehicles IS 2465:1984

In modern automobiles, there is an advanced electrical system where efficient transmission of signals and electricity becomes crucial for smooth functioning. Cables used in motor vehicles are required to function effectively in an environment characterized by constant vibration, changes in temperature, and also oil and water exposure. These cables enable the proper functioning of the lighting systems, ignition systems, control systems and other parts of the automobile, which makes the automobile safe to drive.

BIS certification ensures that the automotive cables have met the standards after thorough testing for the purpose of achieving efficiency. The physical and electrical parameters, including conductor quality, insulation quality, heat resistance and electrical conductivity, must be met by the cables as per IS 2465: 1984. The cable manufacturing companies are required to obtain approval to sell such a product in the market.

What is IS 2465: 1984?

This is the Indian Standard that specifies requirements for electric cables used in motor vehicles. It mentions the material criteria to ensure reliable electrical transmission in automotive applications under varying operating conditions. As per the BIS (Bureau of Indian Standards), these cables are:

Tested for electrical conductivity
Evaluated for heat
Assessed for mechanical strength
Checked for resistance to vibration

Who qualifies for BIS Approval of Vehicle Electrical Cables?

BIS authorisation under IS 2465: 1984 is required for businesses involved in manufacturing, importing, or supplying wiring cables for vehicles in India.

Applicable to:

Manufacturers (India) - Must get BIS approval if the products are covered under QCO.
Foreign Manufacturers - Need certification to export the insulated vehicle cables to India.
Importers/Brand Owners - Must ensure that the products are BIS-certified before sale.
Sellers/Distributors - Should only sell certified vehicle electrical wire products.

Testing and Inspection Requirements

To ensure reliable performance of electrical cables used in motor vehicles, the Bureau of Indian Standards specifies minimum requirements in IS 2465: 1984. This certification ensures that manufacturers produce cables with proper insulation quality, electrical efficiency, mechanical strength, and resistance to harsh automotive operating conditions for safe and stable performance. The BIS testing parameters and quality checks for the cables are listed below:

Oil Resistance Test	Effect of oils, fuels, lubricants on cable material	Ensures performance in automotive fluid exposure conditions
Ozone Resistance Test	Effect of ozone exposure on elastomer insulation	Ensures protection against cracking and weathering
Capacitance Test	Electrical capacitance of insulation (ignition cables)	Ensures correct electrical performance in ignition systems
Abrasion Resistance Test	Resistance of outer sheath to mechanical wear	Ensures long-term durability against friction and rubbing
Flammability Test	Burning behaviour of insulation material	Ensures fire safety compliance in vehicle wiring
Ageing Test (Thermal/Oxygen)	Change in material properties after ageing	Ensures long-term stability of insulation and sheath
Loss of Mass Test	Mass loss after thermal exposure	Ensures material stability under heat ageing conditions
Hot Pressure Test	Deformation under heat and mechanical pressure	Ensures shape retention in extreme operating conditions

How to obtain BIS License for Vehicle Wiring Cables?

The BIS Authorisation process ensures that the automotive circuit wiring cables meet the required standards for proper and efficient operation. This process is set by the Bureau of Indian Standards (BIS) and includes the following steps:

Online Registration: Manufacturers register on the BIS Manak portal by submitting company, factory, and product details. Foreign manufacturers must appoint an Authorized Indian Representative (AIR).
Testing at BIS-Approved Laboratory: Product samples are tested in BIS-approved laboratories for chemical composition, silica content, moisture content, fineness, compressive strength, and other physical performance parameters.
Application Submission: The application is submitted along with test reports, technical documents, and factory details. Foreign manufacturers must also submit AIR-related documents.
Factory Inspection: The Bureau of Indian Standards officials inspect the manufacturing units to verify the production process, safety measures, and quality control system.
Grant of BIS License: Upon successful verification of all requirements, BIS grants the certification license under Scheme-I.
Use of ISI Mark: Once approved, the manufacturer can use the ISI mark on the product with a CM/L number, confirming that the product meets BIS standards.
