Note 1 to entry Monocotyledonous or monocots do not have a cambium and do not produce wood. Lignified
materials may presume a tree-like character by their lignified straws by enclosuring lignin in the cell walls and by
growing tall. Hereby the growth is determined by the primary apical meristem. The diameter of the stems
corresponds to the diameter of the shoot, it becomes hardly thicker. Because of the dissimilarities in the
characteristics compared to wood, e.g. mechanical performance, resistance to fungi and insects, deliquescence, and
lots more, differences in manufacturing of products from lignified materials other than wood result as well as in
their treatment and processability.

Note 1 to entry Dicotyledones or dicots are characterized by cotyledons (seeds with two embryonic leaves) and
produce wood by the activity of the cambium. For the dicots it is the cambium as secondary meristem which is
responsible for the growth of thickness. Intervascular and vascular cambium together form the lateral meristem
between the xylem and phloem. By that wood is built up inwards as secondary xylem.

5 Flooring products characteristics
5.1 Reaction to fire
The reaction to fire performance of a flooring product, whether treated or not, shall be classified in
accordance with EN 13501-1, after being tested in accordance with the test standards given therein and
the relevant reaction to fire class declared.
When tested, the flooring product shall be mounted and fixed in accordance with the same mounting and
fixing conditions used for obtaining the classification of products without the need of testing. This implies
that mounting and fixing will be done in accordance with EN ISO 9239-1, on a substrate of at least Class
D –s2, d0 (or Class A2 –s1, d0 when glued to substrate) and with minimum density of 400 kg/m or with
an air gap underneath. For flooring products with 14 mm thickness or more and for veneered floor
coverings in applications without air gap, an interlayer of at least class E and with minimum thickness of
3 mm may be included.
5.2 Dangerous substances
5.2.1 Content of dangerous substances
Flooring products shall be evaluated concerning their content of dangerous substances, in accordance
with the test methods listed in Table 1.
It is recommended to avoid active use of carcinogens, mutagens or reprotoxics of class 1A and 1B
(excluding formaldehyde). See also EC Regulation REACH [1].
If the substances listed in Table 1 are not added in the manufacturing process of the flooring product and
are not contained in any of its raw materials, and are known not to occur in any stage of the production

5.6 Biological durability
5.6.1 General
Biological durability shall be expressed according to Annex B based on the results of the tests according
to Annex B.
Biological durability of products covered by this standard is determined according to Annex B. The
following types of biological durability are addressed:
— biological durability against basidiomycetes (see B.4.1);
— without treatment expressed as a durability class DC 1 to 5;
— with treatment expressed as a durability class DC 1 to 5, type of treatment and preservative,
penetration class, retention value and target biological agents;
— biological durability against larvae of wood destroying beetles, expressed as DC S (not durable) or
DC D (durable), and the insect species in question (see B.4.2);
— biological durability against termites, expressed as class DC D, DC M or DC S, and the termite species
in question (see B.4.3).
5.6.2 Biological durability testing
If no specific data on biological durability are available, products covered by this standard may be
assigned to durability class 5 (DC 5) “not durable” without further testing. If a higher durability class is
required and/or shall be declared and/or biocides are used, biological durability shall be determined
according to Annex B.
Where several layers are used, the durability class for the weakest layer shall be declared.
5.7 Other characteristics
5.7.1 Raw materials
For bamboo flooring, raw materials shall comply with Annex C.
5.7.2 Moisture content
Moisture content of bamboo flooring shall comply with Annex D.
5.7.3 Hardness
For bamboo flooring, the hardness of the element on the surface side shall be measured and expressed
according to EN 1534.
5.7.4 Bonding
For bamboo flooring, the outer skin (green part) and inner skin (hollow part) shall be removed from at
least the side(s) that will be glued. Figure 7 gives an illustration for this.

5.7.5 Dimensional tolerances
Dimensional tolerances of bamboo flooring shall comply with Annex E.
6 Attestation and verification of constancy of performance
6.1 General
The compliance of product (i.e. flooring products made of lignified material other than wood) with the
requirements of this standard and with the performances declared by the manufacturer shall be
demonstrated by:
— determination of the product type;
— factory production control by the manufacturer, including product assessment.
The manufacturer shall always retain the overall control and shall have the necessary means to take
responsibility for the conformity of the product with its declared performance(s).
6.2 Type Testing
6.2.1 General
All performances related to characteristics included in this standard shall be determined when the
manufacturer intends to declare the respective performances unless the standard gives provisions for
declaring them without performing tests (e.g. use of previously existing data, CWFT and conventionally
accepted performance).
Assessments previously performed in accordance with the provisions of this standard, may be taken into
account provided that they were made to the same or a more rigorous test method, on the same product
or products of similar design, construction and functionality, such that the results are applicable to the
product in question.
