Foreword
IS0 (the International Organization for Standardization) is a worldwide fed-
eration of national standards bodies (IS0 member bodies). The work of
preparing International Standards is normally carried out through IS0
technical committees. Each member body interested in a subject for
which a technical committee has been established has the right to be
represented on that committee. International organizations, governmental
and non-governmental, in liaison with ISO, also take part in the work. IS0
collaborates closely with the International Electrotechnical Commission
(I EC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard IS0 10545-7 was prepared by Technical Committee
lSO/TC 189, Ceramic tile.
IS0 1 0545 consists of the following parts, under the general title Ceramic
tiles:
Part 1: Sampling and basis for acceptance
Part 2: Determination of dimensions and surface quality
- Part 3: Determination of water absorption, apparent porosity, ap-
parent relative density and bulk density
- Part 4: Determination of modulus of rupture and breaking strength
- Part 5: Determination of impact resistance by measurement of coef-
ficient of restitution
- Part 6: Determination of resistance to deep abrasion for unglazed
tiles
- Part 7: Determination of resistance to surface abrasion for glazed
tiles

Part 7:
Determination of resistance to surface abrasion for glazed tiles
1 Scope
This part of IS0 10545 specifies a method for determining the resistance to surface abrasion of all glazed ceramic tiles
used for floor covering.
2 Normative reference
The following standards contain provisions which, through reference in this text, constitute provisions of this part
of IS0 10545. At the time of publication, the editions indicated were valid. All standards are subject to revision, and
parties to agreements based on this part of IS0 10545 are encouraged to investigate the possibility of applying the
most recent editions of the standards indicated below. Members of IEC and IS0 maintain registers of currently
valid International Standards.

3 Principle
Determination of the abrasion resistance of the glaze of tiles by rotation of an abrasive load on the surface and
assessment of the wear by means of visual comparison of abraded test specimens and non-abraded tiles.
4 Abrasive load
The total load on each test specimen shall consist of
‘70,O g of steel balls of diameter 5 mm;
52,5 g of steel balls of diameter 3 mm;
43,75 g of stell balls of diameter 2 mm;
8,75 g of steel balls of diameter 1 mm;
of white fused aluminium oxide of grain size F 80 according to IS0 8486;
310 g
20 ml of deionized or distilled water

5 Apparatus
5.1 Abrasion apparatus (see figure I), consisting of a steel case with an inbuiit eiectrical drive connected to a
horizontal supporting plate with positions for test specimens of dimensions at least 100 mm x 100 mm. The
distance between the centre of the supporting plate and the centre of each position shall be 195 mm. There shale
be equal distances between each adjacent position The supporting plate shall rotate at 300 r/min with an
eccentricity, e, of 225 mm so that every part of each test specimen describes a circular motion of diameter
45 mm. The test specimens are held down with the aid of metal holders which are provided with rubber seals (see
figure 2). The internal diameter of the holders is 83 mm, thus providing a test area of about 54 cm? The thickness
of the rubber is 9 mm and the height of the space under the holder is 225 mm,
The apparatus switches off automatically after completion of a present number of revolutions.
The supporting plate with holders and test specimens shall be covered during operation.
A suitable apparatus of another description may be used, provided it gives the same results as those obtained with
the apparatus described below.
5.2 Apparatus for visual assessment (see figure 3) consisting of a viewing box equipped with fluorescent
lighting of coiour temperature 6 000 K to 6 500 K placed vertically above the surface to be observed providing
300 Ix iiiuminance. The dimensions of the box shall be 61 cm x 61 cm x 61 cm and the inner faces shall be painted
a neutral gray. The light source is screened to avoid direct viewing.
5.3 Drying oven, capable of being operated at (110 + 5) “C.
5.4 Balance (if mass loss is required).
6 Test specimens
6.1 Types of test specimens
Test specimens shall be representative of t he sample . Where tiles have different coiours or decorative effects in
parts of the surface, care should be taken to include ail the distinctive parts.
The usual facial dimensions of test specimens are 100 mm x 100 mm. Test specimens with smaller facial
dimensions shall be fastened close together on a suitable supporting material. Edge effects at the narrow joints
shall be ignored.
