The degree to which a floor tile's surface will
withstand friction (the wear of foot traffic).
Resistance is determined by abrasion tests, and
tiles are grouped accordingly.
2. Abrasion test
ISO Abrasion resistance standards for Glazed tiles
(ISO 10545-7) classify tiles from Group I (suitable
for light residential traffic) to Group V (suitable
for Commercial traffic and passing stain resistance
tests). Unglazed tiles may be tested for resistance
to deep abrasion (ISO 10545-6); results are
expressed as volume of material removed, in cubic

4. Acid resistance
(see Chemical resistance)
(see Bonding Material)
1) A mixture of diverse minerals or other loose
materials in a cementing agent. 2) Fine sand for
mortar and grout. Page 21
7. Alkali resistance

for establishing standards and testing methods for
ceramic tiles in the United States. (see Standards)
9. Anti-slip tiles
(see Slip resistant tiles)
10. Antistatic tiles
(see Conductive tiles)
Decorative feature that simulates grout lines or
joints on a single tile, so that a large tile, for
example, may appear to be four smaller tiles.
12. Attached to net
(see Mounted tiles)<
13. Bas relief
Decorative technique in which design elements are
sculpted or carved to be raised slightly from
14. Base tiles
Trim tiles with a curved edge used at a
perpendicular junction for desired sanitary or
15. Bed (tile)
Layer of mortar or other adhesive that covers the
surface to be tiled and onto which the tiles are
16. Biscuit or Bisque

17. Body (of tile)
The structural portion of a ceramic article, as
distinct from the glaze, or the material or mixture
from which the item is made.
18. Bonding Material
Any of the mortars or adhesives used to install
ceramic tile. Choice of bonding material is
determined by the selection of tile and requirements
of area to be tiled.
19. Border tiles
(see Trim tiles)
20. Breaking strength
The ability of a material to resist breaking or
rupture from a tension force. (ISO 10545-4). B/C
Trim tiles featuring one rounded edge used to finish
wall installations or turn outside corners. Also
Double-Bullnose tiles with two rounded edges.
22. Buttering, also Back-buttering
Applying bonding material directly to the back of a
tile to provide additional coverage in the setting
bed. Technique usually applied to large (8x8"
and up) tiles.
Small, button-like protrusions on the back of a
24. Cap tiles
(see Bullnose tiles)
Box in which tiles are packed. Cartons generally
contain 1-1.5 sq. meters of tile.
26. Carton marking (labelling)
ISO standards specify that tile or its packaging
shall indicate the manufacturer and country of
origin; the mark of first quality; the type of tile
and class)fication (ISO 13006 annex); nominal and
work sizes; whether C the tile is glazed or
unglazed. In addition, symbols may indicate whether
the tile is suitable for floors or walls, the class
of abrasion resistance, and whether the tile is

38. Classification system
Ceramic tiles are classified by the ISO according to
the method of manufacture (extruded, dry-pressed,
other) and to the level of water absorption (see
Natural earthen material, plastic when wet, that is
the basic raw material of ceramic tiles.
40. Cleavage membrane
Sheeting or underlayment panel that separates the
backing surface from the mortar bed and tile,
required when the surface to be tiled is in poor or
unsuitable condition or may be damaged by water.
