BIS CERTIFICATION FOR SWITCHES DOMESTIC & SIMILAR PURPOSES
IS 3854:1997

This standard applies to manually operated general purpose switches intended for use in households with a rated voltage of not more than 440 volts and a rated current of not more than 63 amps. The switches in this standard are suitable for use at room temperature.

This specification also covers the following switches:

• Switches incorporating pilot lights.
• Electromagnetic remote control switches
• Switches incorporating a time delay device.
• Combinations of switches and other functions.
• Electronic switches

Switches that meet this standard are suitable for use at ambient temperatures that do not normally exceed 350C. This standard does not apply to household and similar installation circuit breakers, appliance switches, or cord switches. Switches and boxes must be designed and built in such a way that their operation is reliable and poses no risk to the user or the environment in normal use. In general, compliance is determined by performing all of the specified tests.

Switches with rated voltages of 110 V, 230 V, 240 V, 250 V, 400 V, 415 V, and 440 V are preferred. Switches with rated currents of 6a, 10a, 16a, 20a, 25a, 32a, 40a, and 63a are preferred.

Switches are classified as follows:

• Single pole switches
• Double pole switches
• Three pole switches
• Three pole plus switched neutral switches
• Two-way switches
• Two circuit switches with a common incoming
• Two-way switches with one-off position
• Two ways double pole switches
• Two-way double pole reversing switches

Switches and boxes must adhere to the manufacturer's specifications. Measurement is used to ensure compliance. Switches must be designed in such a way that live parts are not accessible when they are mounted and wired as they would be in normal use. Switches must be equipped with screw clamping terminals or screwless terminals.

Required tests

The following test shall be carried out in a day.

1. Marking
2. Protection Against Electric Shock
3. Electric Strength (Flash Test)
4. Temperature Rise
5. Making and breaking capacity
6. Mechanical Strength
7. Resistance to heat
8. Screws, current-carrying, parts, and connections
9. Creepage distance and clearances
10. Resistance to rusting and so on

Labeling and marking must be done in accordance with IS 3854:1997. Furthermore, for traceability, each switch or its packaging must bear the identification mark in the code. Manufacturers must obtain a BIS license from the Bureau of Indian Standards to use a standard mark (ISI Mark). BIS grant certificate to use the standard mark (ISI Mark) for products under the product certification programme. The certificate can only be given if the product meets the BIS's product specifications.

NOTE:

For Detailed Information about the Procedure for BIS ISI Certification

Conclusion:

If a product falls under the scope of the BIS Conformity Assessment Scheme, All the manufacturers, importers, and foreign entities must obtain BIS ISI Certification. The Bureau may cancel the License if the product fails to meet certification requirements.
