5 Requirements
5.1 Materials
The concrete used in the manufacture of tiles and fittings shall be formed by mixing cement, aggregate and
water and produced by the hardening of the cement paste (cement and water).
NOTE In addition to the basic components the concrete may also contain pigments, admixtures and/or additives.
5.2 Dimensions
5.2.1 Hanging length and squareness
The tile hanging length shall be declared in the manufacturer’s technical specification. For tiles with a regular
front edge, the values of l shall be ± 4 mm of the manufacturer’s declared value when tested in accordance
with EN 491:2004, 5.2.2.1 and 5.2.2.2.
The squareness for tiles with nominally constant hanging length, when tested in accordance with EN 491:2004,
5.2.2.1, shall be calculated as the difference between values l and l and shall be not greater than 4 mm.
2 3
This sub-clause does not apply for tiles that are designed, for example for aesthetic reasons, with an irregular
front edge.
5.2.2 Cover width
5.2.2.1 General
The tile cover width c shall be declared in the manufacturer’s technical specification.
w
NOTE The cover width shunts may also be declared in the manufacturer’s technical specification.
This sub-clause does not apply for tiles that are designed, for example for aesthetic reasons, with a randomly
varying cover width.
5.2.2.2 Interlocking tiles
When tiles with cover width shunts declared by the manufacturer are tested in accordance with EN 491:2004,
5.3.3.1, the cover width shall conform to the following:
 c /10 ≥ c + declared “plus cover width shunt”.
wd w
 c /10 < c - declared “minus cover width shunt”.
wc w
When tiles without cover width shunts, and tiles with cover width shunt but not declared by the manufacturer,
are tested in accordance with EN 491:2004, 5.3.3.1, the mean cover width shall be ± 5 mm of the
manufacturer’s declared cover width.
5.2.2.3 Non-interlocking tiles
When non-interlocking tiles are tested in accordance with EN 491:2004, 5.3.3.2, the mean cover width shall
be ± 3 mm of the manufacturer’s declared value.
5.2.3 Flatness
When tiles are tested in accordance with EN 491:2004, 5.4, the gap between any designed contact point and
the flat surface shall not exceed 3 mm or c /100 mm to the nearest millimetre, whichever is the greater.
w
This sub-clause does not apply where the manufacturer declares that:
 tiles are designed to have less than four contact points to a flat surface; and/or
 tiles are designed to be irregular in flatness.
5.2.4 Fittings
The manufacturer shall identify and declare the dimensions and tolerances and method of measurement of
the fitting relevant to its use. Where relevant, the tile element of a coordinated fitting shall conform to 5.2.1,
5.2.2 and 5.2.3.
5.3 Mass
The mass of tiles and fittings shall be declared in the manufacturer’s technical specification.
When tiles are tested in accordance with EN 491:2004, 5.5, the mean mass shall be:
a) manufacturer’s declared mass ± 0,2 kg for tiles with a declared mass not greater than 2 kg;
b) manufacturer’s declared mass ± 10 % for tiles with a declared mass greater than 2 kg.
5.4 Fixing holes (where provided)
Fixing holes, where provided, shall be arranged so that an intended connection between the tiles and/or
fittings and the batten can be achieved. Details of the size and position of the fixing holes shall be given in the
manufacturer’s technical and/or commercial literature.
NOTE Information on fasteners and fixings is given in Annex C.
5.5 Mechanical resistance (transverse strength)
When tiles are tested in accordance with EN 491:2004, 5.6:
a) value of F shall be not less than the appropriate value given in Table 1; or
min
b) number of individual tiles with transverse strength values (F) less than the appropriate value in
i
Table 1, shall be not more than the appropriate acceptance value in 7.3.
Tiles tested prior to 28 days after manufacture shall be deemed to conform if they reach at least 80 % of the
values specified in Table 1 and the manufacturer can demonstrate statistically that the values given in Table 1
are achieved at 28 days.
Fittings shall conform to 5.2.4 and 5.7.2 (and
