Is there any IS code states the tolerance limit on tile flooring hollowness?

To the best of my knowledge, there is no codal provision.

I had seen a specs of BCA Singapore, in there enhancement series, they mentioned as no hollow sound should come from tiles when tap with hard metal object.

There is CPWD code which speaks of testing the hollowness of tiles by wooden mallet of certain weight and dimension.
