Where this standard is used on NirmanDost

Listed by product makers

5 products in the NirmanDost catalogue name this standard on their spec sheets — Astral CPVC PRO Pipe SDR-11 (Class 1), Astral CPVC PRO Pipe SDR-13.5 (Class 2), Prince Smartfit Plus CPVC Pipe SDR-11 (Class 1). 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.
