IN WHICH DOCUMENT ZERO FIRE RATING IS MENTIONED?

Hi Mr. Akash,
Zero rating of the product is inferential, no standard mentions it categorically but based on ASTM or Indian Standards mentioning very clearly that the System is Fire rated. It also means even if we use the best Firestop product and the walls or floors are not Fire rated, then the entire system will fails. Asking for Fire rating of Product is technically and logically not the right way and considered to be incorrect. All standards mention Fire rating of the system not for specific product, e.g. - UL, Intertek etc.
