A

1. Abrasion resistance
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 mm.
3. ACI
American Concrete Institute
4. Acid resistance
(see Chemical resistance)
5. Adhesive
(see Bonding Material)
6. Aggregate
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
(see Chemical resistance)
8. ANSI
American National Standards Institute, responsible 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)
11. Apparent joint
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 background
14. Base tiles
Trim tiles with a curved edge used at a perpendicular junction for desired sanitary or aesthetic design.
15. Bed (tile)
Layer of mortar or other adhesive that covers the surface to be tiled and onto which the tiles are set.
16. Biscuit or Bisque
(see Body of Tile)
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
21. Bullnose tiles
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.
23. Button-back
Small, button-like protrusions on the back of a ceramic tile.

24. Cap tiles
(see Bullnose tiles)
25. Carton
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 frostproof.
27. CCB
Italian Ceramic Center of Bologna (Italy). (Centro Ceramico di Bologna) CCB is the official laboratory for Research, Testing, and Analysis of Ceramic Materials and Products in Italy. The Center is located at Via Martelli 26, Bologna, 40138 Italy. e-mail: centro.ceramico@cencerbo.it
28. CEN
European Committee for Norms and Standards, responsible for establishing standards and testing methods for ceramic tiles in Europe. (see Standards)
29. Ceramic litho
(see Decal)
30. Ceramic tiles
A flat, cladding or building material, of relative thinness, composed of clays and fired to hardness. The face may be glazed or'unglazed.
31. CERLABS

European network of National Ceramic Laboratories.
32. Certification system
(see Standards)
33. Chemical resistance
The ability of a tile surface to withstand damage from chemicals, acids, alkalis and swimming pool salts in accordance with ISO testing methods (ISO 10545-13).
34. China tiles
(see Impervious Tiles)
35. Chip resistance
(see Impact resistance)
36. Cigar tiles
(see Pencil Tiles)
37. Cladding
Covering, particularly wall covering.
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 page 9).
39. Clay
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.
