Why Explosive Atmospheres - Part 1: Equipment Protection by Flameproof Enclosures "d" needs BIS certification
Explosive Atmospheres - Part 1: Equipment Protection by Flameproof Enclosures "d" falls under the Electrical & Electronics category and is covered by IS/IEC 60079: Part 1 (2014). Manufacturers and importers must obtain the ISI mark licence from the Bureau of Indian Standards before the product can be manufactured, imported, stored or sold in India. Selling a notified product without a valid BIS licence can lead to seizure of stock, marketplace delisting and penalties under the BIS Act, 2016.
Testing & costs
Sample testing for IS/IEC 60079: Part 1 (2014) is currently available at 4 BIS-recognised laboratories across India. Reported test charges range from ₹1.2L – ₹2L (excluding GST), depending on the laboratory, the number of models/varieties and the tests included in the scope. Certko can help you pick a lab that balances cost, turnaround time and location.
