Industry Outlook

Indian Standard 9968 was adopted by the Bureau of India Standards (BIS) in 1953, following the finalization of the draft by the Power Cables Sectional Committee, which had been approved by the Electrotechnical Division Council.

This standard is basically applicable to Elastomer insulated cables, which are generally used for the purpose of mining, ship wiring, transportation sector, and Defense applications & earth moving machines.

Considering the crucial role of elastomer insulated cables, it can be seamlessly concluded that they play a major role in economic development, since mining, ship wiring defense application, and other uses play a direct role in our economy. 

That’s why, keeping the public interest in view, it is essential to meet the compliance requirements to ensure that a product meets the specifications of Indian Standards. Moreover, to ensure conformance with compliance requirements product testing is conducted, since it is mandatory to obtain a BIS certification to sell or import elastomer insulated cables in India. 

For more information with respect to the benefits of the product, testing let’s move to the next section.

Why is Product Testing Crucial | Importance of Product Testing

  • One of the most important purposes of testing is the quality assurance of a product that reflects high quality, safety, and reliability.
  • Product testing allows the manufacturer to ensure conformance with established technical standards to produce high-quality and safe products.
  • Build reputation and maximize the profit, considering that a tested product indicates quality assurance. 
  • Helps in retaining customers, thus, providing a competitive edge.
  • Helps in understanding distinct types of stress a product can endure, be it in case of weather, wear tear, and other conditions.
  • In the initial prototyping stage, if you are trying to avail investment in order to manufacture your product in mass quantities, a tested product can allow you to achieve patent and investors as it shows the quality and functionality of the product.

With the benefits of product testing, we can clearly estimate how testing ensures quality assurance and product credibility. For a better understanding, let’s have a look at an example, 

Through product testing, it can be easily proved that electrical cables are safe to use, however, in case of any defects are found during product testing, can be seamlessly eliminated.

Since, it has been established how essential product testing is, now let’s move to the benefits of complying with standards.

What Are the Benefits of Complying With Standards?

Complying with standards offers numerous benefits to manufacturers and importers of the product, which further helps in building trustworthiness and reliability, thus retaining the customers.

Why, don’t we look at other benefits of the same -

  • A certified product acts as a shield against penalties and fines which could be imposed for not certifying a product.
  • A certified product serves as evidence that a product has been tested and certified as per prescribed standards.
  • A certified product provides a sense of security and safety to the consumers, thus ensuring easy acceptance.
  • It provides a competitive advantage over competitors.
  • Easy market acceptance as a product is tested and certified.
  • Confirm the unmatched quality standards.
  • Seamless to file government tenders.

With these benefits of ensuring conformance with IS 9968 standards and specifications, a manufacturer can establish that a product is safe, reliable, and credible, thus, confirming unmatched quality standards. 

Now, in the next section, we will learn about the test requirements and product scope of the IS 9968.

Product Scope

IS 9968 part 2, covers the requirements of heat resisting elastomer insulated cables for fixed installation and flexible cables for single phase and three-phased systems, appropriate for voltage of 3.3 kV up to and including 33 kV.

These cables are appropriate for use where the combination of ambient temperature and temperature increase because of the load results in a conductor temperature not exceeding 90-degree under normal operating conditions and 250-degree under short circuit conditions. 

In the next section, let’s have a look at the Test requirements in the next section -
