The
Standards
Uniceramic
products conform with the Lebanese standards (NL), European
Standards (EN), British Standards (BS), Saudi Standards
and the American Standards (ASTM) and finally the ISO
standards. In order to understand these conformances
and the relationship between all of the above standards,
we will explain below.
Usually standards are defined and published by national
standardization bodies in each country, established
for this purpose and composed by groups and individuals
active in production, research, characterization and
use of various materials in the ceramic industry. The
various countries have established their own standards,
but to promote the international market, and thus a
much more free circulation of products in a variety
of markets, the need for international standards common
to the different nations has been recognized in recent
years. To equalize standards in different countries,
international institutes of standardization have been
established to incorporate the national standards agencies
of the individual countries.
• CEN – International Committee for Standardization
(Comite European De Normalisation) includes the standards
organizations of the European countries, publishes the
EN Standards.
• ISO – The International Organisation for Standardization,
includes all the world’s national standards (Valid
all over the world) and publishes the UNI EN ISO standards
for Ceramic tiles.
What
the present EN ISO standards on tiles include:
1- A classification of ceramic tiles into groups based
on water absorption. Uniceramic tiles are classified
into the following groups:
a. UNI EN 176 ISO BI (water absorption 0.5 % to 3 %)
anti frost floor and swimming pool tiles
b. UNI EN 177 ISO BIIa (water absorption 3% to 6 %)
floor tiles
c. UNI EN 159 ISO BIII (water absorption over 10 %)
Wall tiles.
d. The general ISO standard containing and defining
the above is ISO 13006:1998
e. For details about these standards go to ISO website:
www.iso.org/iso/en.
2-
A definition of the properties that the tiles of each
group must possess, in relation to their intended use.
3- A specification and description of the methods of
measurement for various properties according to ISO
10545 part 1 thru 16.
4- An Indication of the acceptability requirements that
tiles in each group must meet for each property. The
requirements are essentially limits or benchmarks to
which the tiles must comply in order to be considered
of good quality.

Tile
Usage guide and classification: ABRASION
Uniceramic tiles are classified according to the PEI
abrasion resistance method stated in ISO 10545 part
as follows:
Class
Usage
Class I Light traffic for residential
bathroom floors
Class II Medium-light traffic, residential
interiors with the exceptions of kitchens, stairs and
areas near external areas
Class III Medium-heavy traffic, all residential
applications. Suitable for all applications that are
similar to residential applications in terms of traffic.
Exceptions are areas at entrances of buildings and where
there are prevalent circulations or turning points.
Class IV Heavy traffic, all residential areas
and most commercial areas such as public places and
commercial halls.
Class V Extra heavy traffic, all residential
areas and public places including building entrances.
Stain Resistance: As per ISO standards, Uniceramic tiles
are stain resistant as per the following classifications:
AA- Products on which the tests produced no visible
effect i.e no sign of any staining agent
A- products on which the tests produced a slight change
in appearance.
