The Indian Standard was adopted by the Bureau of Indian Standards following approval from the Electrotechnical Division Council, which endorsed the finalized draft put forth by the Equipment for Electrical Measurement and Load Control Sectional Committee.

IS 13779:1999 lays out the general requirements and testing protocols for a range of AC static watt-hour meters falling under classes 1 and 2, typically akin to induction meters. This Indian Standard was adopted by the Bureau of Indian Standards subsequent to approval from the Electrotechnical Division Council, endorsing the finalized draft originating from the Equipment for Electrical Measurement and Load Control Sectional Committee.

This standard delineates static watt-hour meters falling within accuracy classes 1 and 2, devised for measuring alternating-current electrical active energy across frequencies spanning from 45 Hz to 55 Hz. These meters cater to single-phase, three-phase, balanced, and unbalanced loads. It exclusively pertains to static watt-hour meters comprising a measuring element and register housed within a meter case. Additionally, it encompasses the operation indicator and test output. Furthermore, it extends to meters featuring multirate tariffs and those capable of measuring energy in both directions.

Meters are categorized into Class 1 and Class 2. They must be meticulously designed and constructed to eliminate any potential hazards during typical usage and under standard conditions. This ensures personal safety against electric shock, protection from high temperatures, prevention of fire propagation, and resilience against solid objects, dust, and water ingress.

TESTS

The specified tests must be conducted for ac static watthour meters.

• General and Constructional Requirements

• a.c. High Voltage Test

• Insulation Test

• Accuracy Requirements (Limits of Error)

• Test of starting condition

• Test of no-load condition

• Power Consumption

Marking must adhere to standard specifications, with each meter displaying the required information outlined in the standard. Manufacturers are mandated to acquire 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 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.
