Question associated with the intended tile use: a surface that will be subject to pedestrian and/or vehicular traffic [flooring o floor] or that will not be subject to traffic [wall tiling or cladding], independently of its spatial position (horizontal, vertical, or sloping).
What type of traffic?
The tile will be part of a floor subject to pedestrian and vehicular traffic, or will only be subject to pedestrian traffic, in regard to the mechanical strength that it will need to display.
What intensity pedestrian traffic?
Question related to the number of persons that will foreseeably cross the floor daily. This is related to standard uses such as:
Low traffic: Floors in private dwellings [fewer than 10 persons/day]
Intermediate traffic: Common-use floors in intermediate apartment buildings and small commercial buildings [between 10 and 250 persons/day]
High traffic: Floors in publicly trafficked architecture [more than 250 persons/day]
Is it intended for exteriors or interiors?
Question related to durability in relation to external agents and foresight in regard to slip resistance with rain or frost.
Is there frost risk?
To be taken into account in geographic areas that have harsh winter climates with frost [temperature drops to -5oC or lower at least 5 days per year].
Is it directly accessible from outdoors?
In the sense of access from the street or outdoors, except accesses from terraces, balconies, and galleries in dwellings in high-rise buildings, where there is no risk that abrasive material will be carried in by footwear, and wetting by water being carried in is very unlikely.
What tile-to-tile spacing?
Question related to the installation mode in regard to the physical spacing between adjacent tiles; i.e. the joint width. Ranging from a butt-joint tile installation [NEVER RECOMMENDABLE] to a wide-joint tile installation [5 mm or larger inter-tile spacing].
Glazed or unglazed ceramic tile?
In regard to whether the tile fair surface is coated or not with a glaze whose nature and appearance differs from those of the tile edges and back.
What size tile?
Question related to the dimensions (size), usually length and width, which yield the module surface area [length x width in rectangular and square tiles], expressed in square centimetres. For example 900 cm2 (30 x 30 cm), 1200 cm2 (30 x 40 cm), 1600 cm2 (40 x 40 cm).
Do you wish to include the permissible maximum tolerances according to standard EN 14411 in the questionnaire?
Standard EN 14411 establishes the permissible maximum tolerances as a function of the product group and, in certain cases, the tile size. If you wish to include these tolerances in the questionnaire, you will need to indicate the selected product group and, where appropriate, the surface area or longest side.
Standard EN 14411 classifies ceramic tiles according to their manufacturing process and water absorption capacity (E). The specifications of the standard are applied to first-quality ceramic tiles made by extrusion (A) or pressing (B), sexcept the unglazed pressed tiles of group III; i.e. those with code BIII UGL.
Precision or natural extruded ceramic tile?
Extruded ceramic tiles (A) can be marketed as Precision tiles (smaller allowed maximum dimensional tolerances) or Natural tiles (larger allowed maximum dimensional tolerances).
Surface area of the tile (S) in square centimetres (length x width)?:
Longest side (L) in centimetres?
BIII GL tiles with spacer lugs?
BIII GL earthenware tiles include different (dimensional) specifications depending on whether they are marketed with spacer lugs or without them, though these differences in projecting edges are in disuse, at least in the European Union.
Surface area of the tile (S) in square centimetres (length x width)?
Does the intended tile use demand special requirements?
The foregoing questions addressed the requirements of most ceramic tile uses. However, certain special applications may require special properties not envisaged in the previous questions, or particular levels for those properties. Those entail a further specific questionnaire.
A "NO" answer will activate the automatic answer to the questionnaire.
A "YES" answer will require filling in a new questionnaire
