Flooring, Wall Finishing and Roofing Sectional Committee, CED 05
FOREWORD
This Indian Standard (Part 2) (Second Revision ) was adopted by the Bureau of Indian Standards, after the draft
finalized by the Flooring, Wall Finishing and Roofing Sectional Committee had been approved by the Civil
Engineering Division Council.
This standard (Part 2) was first published in 1992 and subsequently revised in 2006. This second revision standard
incorporates the experience gained with the use of its first revision, this standard and brings the standard in line
with the latest developments in this field.
In this revision an alternate vacuum method to measure the water absorption has been introduced.
This Indian Standard is published in several parts. The other parts in this series are:
   Part 1     Determination of dimensions and surface quality
   Part 3     Determination of moisture expansion using boiling water
   Part 4     Determination of linear thermal expansion
   Part 5     Determination of resistance to thermal shock
   Part 6     Determination of modulus of rupture and breaking strength
   Part 7     Determination of stain and chemical resistance of unglazed tiles
   Part 8     Determination of stain and chemical resistance of glazed tiles
   Part 9     Determination of crazing resistance of glazed tiles
   Part 10    Determination of frost resistance
   Part 11    Determination of resistance to surface abrasion of glazed tiles
   Part 12    Determination of resistance to deep abrasion of unglazed tiles
   Part 13    Determination of scratch hardness of surface according to Mohs’ scale
   Part 14    Determination of impact resistance by measurement of coefficient of restitution
   Part 15    Sampling and basis for acceptance
   Part 16    Determinations of lead and cadmium given off by glazed tiles
In the formulation of this standard considerable assistance has been derived from the ISO 10545-3 :1995
‘Ceramic tiles — Part 3: Determination of water absorption, apparent porosity, apparent relative density and bulk
density’.
The composition of the Committee responsible for the formulation of this standard is given in Annex A.
In reporting the results of a test or analysis made in accordance with this standard, if the final value, observed or
calculated, is to be rounded off, it shall be done accordance with IS 2 : 1960 ‘Rules for rounding off numerical
values (  revised  )’.
