In formulation of this standard considerable assistance has been derived from the ISO
10545-13:1995 Ceramic tiles -- Part 13: Determination of chemical resistance.
For the purpose of deciding whether a particular requirement of this standard is
complied with, the final value, observed or calculated, expressing the result of a test or
analysis, shall be rounded off in accordance with IS 2:1960 `Rules for rounding off
numerical values (revised)’. The number of significant places retained in the rounded off
value should be the same as that of the specified value in this standard.

7 TEST SPECIMEN
7.1 For Stain Test in accordance with 2.1
Five unused and undamaged whole tiles or if the tiles are very large, they may be cut to a
dimension of 200mm x 200mm. The test specimen shall be thoroughly cleaned with water and
then dried in the oven (3.3) adjusted to a temperature of 110  5 oC until a difference in mass of
less than 0.1g is reached between two successive weighing.
7.2 For Chemical resistance test in accordance with 2.2, 2.3 and 2.4
Five test specimens shall be used with each test solution. The specimens shall be cut from
whole tiles that are free from surface defects to a dimension of 50mm x 50mm such that at least
one side of each test specimen is not a cut side.
The surface of the specimens shall be thoroughly cleaned with a suitable solvent, such as
methanol. The test specimen shall be thoroughly cleaned with water and then dried in the oven
(3.3) adjusted to a temperature of 110  5 oC until a difference in mass of less than 0.1g is
reached between two successive weighing.
8 PROCEDURE
8.1 Application of the staining agent
Spread 3 or 4 drops of the paste (2.1.1 or 2.1.2) on to the surface of the test specimen. Place 3
or 4 drops of each of the solution (2.1.3 and 2.1.4) to cover separate areas of the tile surface.
Place a convex watch glass of an approximate diameter of 30mm on the applied drops, in order
to spread them to an approximately circular area. Leave the staining agents in place for 24hr
8.2 Stains cleaning procedure
8.2.1 Procedure A
Clean the test specimen with running hot water (4.1) for 5min,then wipe the surface with a damp
cloth

CED 5 (10838)WC
November 2016
8.2.2 Procedure B
Clean the test specimen manually with the weak cleaning agent (4.2), using a natural, nonabrasive sponge or a cloth, then rinse with running water and finally wipe it with a damp cloth.
8.2.3 Procedure C
Clean the test specimen mechanically for 2min with the strong cleaning agent (4.3), using an
apparatus with a rotating brush with hard bristle having a diameter of 8cm and with an rpm 500
rev/min. Then rinse the surface with running water and wipe with a damp cloth
8.2.4 Procedure D
Immerse the test specimen for 24h in a suitable solvent (4.4, 4.5, 4.6), and thoroughly rinse with
running water and wipe with a damp cloth. Cleaning is considered to be accomplished if any
one of the solvents 4.4 or 4.5 or 4.6 removes the stain
8.3 Attempts to remove stains
Subject the test specimens treated according to 6.1 to the successive cleaning procedure as
described in 6.2 (procedure A, B, C, D)
After each cleaning procedure, dry the test specimen in the oven at a temperature of 110+/- 5
deg c and subject them to a visual examination. Examine the surface with naked eye or with
spectacles, if usually worn, at a distance of 25 to 30cm in daylight or artificial illumination of
300lx.
8.4 Application of household chemicals, swimming pool salts, and acids and alkalis ( 2.2, 2.3
and 2.4)
Use the test solutions listed in 2.2, 2.3, and 2.4. Immerse the test specimens vertically to a
depth of 25mm in the vessel (3.1) containing the test solution. The non-cut side of each test
specimen shall be fully immersed. Cover with the lid (3.1) and maintain at 24  2 oC for 12 days
After 12 days subject the test specimen to running water for 5 days and then boil them for 30min
while completely immersed in water. Remove the test specimen from the water, dab with a wet,
but wrung-out chamois leather and dry in the oven adjusted to 110  5 oC
9 CLASSIFICATION OF RESULTS
9.1 Stain Test
9.1.1 The performance of the tile in the stain resistance test shall be classified as shown in
Figure 1
9.1.2 Follow the stain cleaning procedure in accordance with 6.2 and 6.3. If there is no visible
effect, i.e, if the stain has been removed, record the cleanability class according to Figure 1. If
the stain is not removed, proceed to the following cleaning procedure.
9.1.3. Class 5 corresponds to the greatest ease of removing the particular stain; Class 1
corresponds to the impossibility of removing the particular stain with any of the test procedures
and/or to irreversible damage to the proper surface.

examine the parts of the cut edges that were immersed. Daylight or artificial illumination is
permitted (approximately 300 lx), but direct sunlight shall be avoided.
9.2.2 Any changes to the tiles surface due to chemical attack, other than a slight change in hue,
when examined in accordance with 7.2.1 shall be noted. Tiles shall be classified as follows
9.2.2.1 For test solutions listed in 2.2 and 2.3
