Does Your AC Static Watt-Hour Meter Require BIS ISI Certification Under IS 13779?

An electricity meter has the function of recording power usage and also aids in working out how much electricity a consumer has to pay. Since even a minor error in measurement can have an impact on the accuracy of the bill, the quality and reliability of electricity meters is a major issue for manufacturers, utilities, and consumers.

For any business that manufactures or imports AC static watt-hour meters into India, obtaining BIS ISI Certification for AC static watt-hour meters is an important matter regarding compliance. As per the Indian Standard, IS 13779:2020, the specifications concerning performance, accuracy, and electrical safety of AC static watt-hour meters Class 1 and Class 2 have been laid down.

However, does it really matter whether all such meters must necessarily be compulsorily certified under the ISI mark? An insight into the present situation, Quality Control Orders, and special requirements for the product should be gained before manufacturing, importation, or sale in India.

Is Certification According to IS 13779 Made Mandatory by BIS ISI?

It all comes down to the regulatory requirements in question and the specific product in question that is being manufactured or imported.

The BIS Standards Portal shows that IS 13779:2020 – AC Static Watt-hour Meters, Class 1 and 2 – Specification is identified and currently has its certification status listed as voluntary. But here, the BIS Scheme-I classification of AC static watt-hour meters under IS 1379 is mandatory for certification. The company would have to verify the QCO concerned, its current status, the scope of the product, and any amendments made thereto before coming to the conclusion about whether certification is mandatory for them.

This is important for the manufacturers as the legal implications of voluntary certification and compulsory certification are different.

What Does IS 13779 Cover And Which meters does it include?

IS 13779:2020 is the Indian Standard applicable to AC static watt-hour meters of accuracy Classes 1 and 2; these meters measure the active electrical energy consumed over a period of time and are generally used in electricity metering applications.
