Industry Outlook

IS 16227 Part 2 includes specifications with respect to instrument transformers which are commonly used to operate instruments or metering from high voltage or high current circuits. 

Considering the crucial role played by cables in major industries of India, Bureau of Indian Standards had introduced the mentioned standards keeping in view of public interest. That’s why, BIS certification is a mandatory requirement for cables, for the purpose of quality assurance. 

The use of cables in these industries could affect the Indian economy as a whole, since these industries have a major impact on economic growth. 

Though, to ensure the manufacturing or importing of high quality products, certain tests are conducted that serves as a proof of high quality assurance and credibility.

Basically, the mentioned standard includes the information in respect to the test to be conducted on the electrical cables to check their quality and credibility to reflect that certain technical standards have been followed. Particularly, product testing is crucial to ensure that a product is safe and reliable, which is important to stay ahead of the competition and to maximize the reputation and profits.

Above all, product testing helps you retain the consumers through meeting their expectations. For a better understanding of why product testing is important, let’s have a look at why product testing is crucial.

Why is Product Testing Crucial | Importance of Product Testing

  • One of the most important purposes of testing is quality assurance of a product that reflects high quality, safety, and reliability.
  • Product testing allows the manufacturer to ensure the 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. 

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, that 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 an 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 16227 Part 2 standards and specifications, a manufacturer can establish that a product is safe, reliable, and credible, thus, confirming to unmatched quality standards.
