BIS Checks For Electric Immersion Water Heaters

Introduction

Running a product in today’s market is tough without steady quality and the right mark. A BIS mark may be needed for selling in India. Makers have to follow the points set in the Indian Standard before they move ahead.

IS 302 2 201 2008 talks about electric immersion water heaters. It was taken up after the draft was cleared by the Electrotechnical Division Council.

The paper addresses safety requirements of portable immersion heaters in residential and low-intensity workplaces. These heaters do not operate beyond 250 V. Not all appliances are suitable to be used by people at home, but they can still find their way to the small shops, light industry, or farms; thus, the safety considerations apply there as well.

An immersion heater is made by placing a heating wire inside a ceramic tube. This tube sits inside a metal cover. The cover can be copper, steel, cast iron, titanium, or a PFA-coated type.

Tests for Electric Immersion Heaters

• Earth continuity test
• Electric strength test
• Functional test
• Protection against access to live parts
• Power input and current check
• Heating check
• Leakage current and electric strength at working heat
• Leakage current and electric strength
• Mechanical strength check
• Internal wiring check
• Supply connection and cord check
• Terminals for external conductors review
• Provision for earthing
• Screws and connections review
• Stability and mechanical hazards review

These checks are carried out in a proper lab that follows the methods in the standard.

Groups Under GoL

• Group I up to 1000 W
• Group II above 1000 W

The producer must provide the samples of what they would like to license. In IS 302 2 201 2008, the points are followed by the marks and labels. The product must satisfy the previously mentioned points, and the ISI mark can be added upon granting of the license.

A BIS licence for immersion heaters is given only after the factory setup, process flow, and testing setup are checked in person.

For more details, you can read about the steps for Indian makers and foreign makers on the BIS portal.

Conclusion

Any product that falls under this scheme has to carry a BIS ISI mark. If a product does not meet the needed points, the licence may be withdrawn. Presto Laboratories helps makers and traders meet the rules for selling their items in the Indian market.
