Ranking use & Ranking fire

Use classification in accordance with European standard NF B53-669, used to classify parquet flooring according to its residential, commercial or industrial use, to guarantee its durability.

Ranking use & Hardness rank of species

In France, parquet flooring is classified according to its use, which is based on the correlation between the species and the thickness of the top layer. This classification determines the parquet’s ability to resist the demands of a particular environment, based on the frequency of traffic and potential wear and tear. In High Trafic range parquet, the ROC Varnish finish is made to satisfy the demand of high-traffic environments. In addition, a rigorous selection of species and an optimised wear layer thickness guarantee exceptional durability for public or commercial spaces where resistance to impact and scratches is essential.

Hardness Rank of Species		Thickness of the top layer
		e ≥ 2,5 mm	e ≥ 3,2 mm	e ≥ 4,5 mm	e ≥ 7 mm
		LOFT 13/14 thick LOFT PRO 11 thick	MASSIF 9/10 thick LOFT PRO 12/15 thick LOFT 14 thick	MASSIF 14 thick LOFT PRO 16 thick LOFT PRO 20 thick	MASSIF 20/23 thick LOFT PRO 20 thick
B	Semi hard wood: Walnut, Teak	21	22	23	31
C	Hard wood: Acacia, Afrormosia, Beech, Oak, Doussie, Maple, Ash, Iroko/Kambala, Moabi	23	31	33	34
D	Very hard wood : Amarante, Cabreuva, Ebony, Jatoba, Merbau, Padouk, Wenge, Zebrano	31	33	34	41

Domestic use rank

Parquet is classified according to the use classes defined below. The UPEC classification does not apply to parquet insofar as it can be renovated. The classification takes into account 4 criteria: Wear, Punching, Water and Chemistry. However, equivalences between the class of use and the UPEC classification are possible.

Previously, the classification of material reaction to fire was established according to 5 categories : M0 corresponded to the materials with no reaction to fire, noncombustible, as concrete, brick, plaster… Nowadays, the regulation has changed since the European directive 89/106/CEE. The M classification is now the Euroclasse, and distinguishes floor materials from others (wall, ceiling). The Euroclasse A1 corresponds to a noncombustible materials. For wood flooring, the ranking is conventional and without specific treatment in order to improve the fire reaction. It is ranked Cfl-s1 (fl for floor), s1 is low smoke emission.
