Where this standard is used on NirmanDost

Listed by product makers

3 products in the NirmanDost catalogue name this standard on their spec sheets — Dalmia Infra Pro, JSW Concreel HD Cement, MP Birla Cement Unique (PSC). 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.
