Listed by product makers
3 products in the NirmanDost catalogue name this standard on their spec sheets — BirlaNu Aerocon AAC Blocks, Magicrete AAC Blocks (Autoclaved Aerated Concrete), NXTBLOC AAC Blocks. 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.
