This standard specifically addresses induction-type watt-hour meters, featuring accuracy classes 0.5, 1, and 2, specifically engineered for the measurement of alternating current electrical active energy. It encompasses the assembly of meters and associated accessories, such as current transformers, enclosed within the meter case. Notably, it excludes maximum demand indicators addressed by IS 8530.

This standard is relevant to multi-rate meters but excludes other specialized meter types or those intended for testing purposes, as outlined in IS 11426. Meters are categorized according to their class indices, including 0.5, 1, or 2.

Meters must be engineered and constructed to ensure safety under typical usage and environmental conditions. They should possess sufficient mechanical resilience to endure temperature variations commonly encountered during regular operation.

TESTS

The specified tests must be conducted for ac watthours meters of class 0.5, 1, and 2.

1) Type Test

• Insulation resistance

• Running with no load

• Starting

• Power loss

• Heating

• RImpulse voltage test

• ac voltage test

• Sustained accuracy test and so on

2) Acceptance test

• Insulation resistance test

• Running with no load

• Limits of errors

• Test of meter constant

• Repeatability of error and some other tests

3) Routine test

• Insulation resistance

• Starting

• Running with no load

• Limits of error

Packing and labeling procedures must adhere to established standards. Each meter must prominently display information outlined in the standard, and may also feature the Standard Mark (ISI Mark). Manufacturers are required to obtain a BIS license from the Bureau of Indian Standards to utilize the standard mark (ISI Mark). This license is granted following a thorough evaluation of manufacturing infrastructure, production processes, and quality control and testing capabilities conducted during an on-site visit to the manufacturing premises by the Bureau.

PROCESS FOR BIS ISI MARK CERTIFICATION

BIS CERTIFICATION PROCESS

Acquiring a BIS license requires a comprehensive review of manufacturing infrastructure, quality control abilities, testing resources, and production procedures. This thorough assessment guarantees that products not only adhere to regulations but also prioritize consumer safety and reliability.
