Where this standard is used on NirmanDost

Listed by product makers

5 products in the NirmanDost catalogue name this standard on their spec sheets — Dalmia Infra Pro, Ramco Supergrade Cement, MP Birla Cement Perfect (PPC). 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.
