Where this standard is used on NirmanDost

Listed by product makers

9 products in the NirmanDost catalogue name this standard on their spec sheets — Arteor Modular Wiring Devices Range, Arteor Indian Standard Sockets - Square White Mechanism, Arteor Indian Standard Sockets - Square Magnesium Mechanism. That is the maker’s own claim, copied as printed; we have not tested these products against the standard, and a spec sheet can cite the wrong code.
