IS 7098 (Part I) ELECTRICAL- CABLES & WIRES
Indian Standard 7098 includes specifications for cross-linked polyethylene insulated PVC sheathed cables for electrical supply and control purposes. Since these cables are used for electrical supply and control, it is critical to understand that these components of the electrical power industry affect the economy as a whole, if conformance with compliance requirements is not maintained.
Considering this, the Bureau of Indian Standards introduced IS 7098 dated 22 December 1988, after the finalization of the draft by the Power Cables Sectional Committee had been approved by the Electrotechnical Division Council.
The major issue behind the introduction of this standard was to establish mandatory standards for cross-linked polyethylene insulated PVC sheathed cables, keeping in view of public interest, including providing safe, credible, and reliable products to consumers.
Moreover, since it is mandatory to comply with the specifications for cross-linked polyethylene insulated PVC sheathed cables, it helps you not only retain customers but also provides a competitive advantage.
To attain the benefits of a product must be tested and certified as prescribed by the concerned standard. Here, in the next section refer to the below-mentioned 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 found during product testing, it provides an opportunity to eliminate those.
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 7098 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 7098.
IS 7098 Part 1, covers the requirements of distinct XLPE cables, it could be, armored and unarmoured single, twin, three, four and mum-core crosslinked polyethylene (XLPE) insulated and PVC sheathed cables for electric supply and control purposes. Moreover, cables covered under India Standard 7098 Part 1 are appropriate for use on single phase or three phases (earthed or unearthed) systems for rated voltages up to and including 1100 V. These cables may be used on the systems or rated voltages up to and including 15OO V to earth.
