BRIEF HISTORY
The IS0 Recommendation R 631, Mosaic Parquet Panels, was drawn up by Technical
Committee ISO/TC 99, Semi-manufactures of Timber, the Secretariat of which is held by Oficiul
de Stat Pentru Standarde (OSS).
Work on this question by the Technical Committee began in 1960 and led, in 1963, to the
adoption of a Draft IS0 Recommendation.
In November 1964, this Draft IS0 Recommendation (No. 756) was circulated to all the IS0
Member Bodies for enquiry. It was approved, subject to a few modifications of an editorial
nature, by the following Member Bodies:
Australia Hungary Romania
Belgium Iran Switzerland
Czecoslovakia Japan Turkey
France Netherlands U.S.S.R.
Germany New Zealand Yugoslavia
Greece Poland
No Member Body opposed the approval of the Draft.
The Draft IS0 Recommendation was then submitted by correspondence to the IS0 Council,
which decided, in November 1967, to accept it as an IS0 RECOMMENDATION.

IS0 Recommendation R 631 November 1967
MOSAIC PARQUET PANELS
I 1. SCOPE
The scope of this IS0 Recommendation is
- to set down the manufacturing conditions for mosaic parquet panels made from any species
of wood;
- to specify the characteristics of the panelsand panel components of mosaic parquet panels
and to classify them according to their quality and appearance;
,
- to specify the state upon delivery and the packaging and marking conditions of mosaic parquet
L
panels.
This IS0 Recommendation applies only to mosaic parquet panels made up from rectangular
fingers, forming component squares laid in a chequered pattern and intended to be bonded (or
fixed) to a supporting base, edge to edge, either directly or with an interlayer of adequate material.
2. TERMINOLOGY AND DESIGNATION
2.1 Mosaic parquet panel
Aggregate made up from wooden components (fingers) laid on a single layer and preas-
sembled by juxtaposition, either by means of a material temporarily fixed (paper glued on
the face for example) or of a sufficiently flexible material, permanently fixed.
.
b
Generally the panel is square in shape, being made up from fingers assembled in compo-
nent squares, laid in a chequered pattern (see Figure 1, below). Other patterns may also be
formed.

2.2 Finger (of mosaic parquet)
Solid wood component of small dimensions, having regular form and planed edges (see
Figure 2, below).
FIG. 2. - Finger
2.3 Component square
Assembly of fingers placed edge to edge making up a square, the side of which is equal to
the length of the finger.
2.4 Designation
Mosaic parquet panels corresponding to this IS0 Recommendation should be designated
by specifying, in the order given below, the following
- the words “mosaic parquet”;
- thickness of the fingers, in millimetres;
- length and width of panel, in millimetres;
- number of fingers per component square;
- class (see clause 4.2), in Roman figures;
- species of wood.
Example: Mosaic parquet 8 x 400 x 400 - 5-1, oak.
3. MANUFACTURE
The characteristics specified below refer to fingers with a reference moisture content of 11 %
3.1
of dry weight.
NOTE. - This reference moisture content is not inconsistent with the moisture limits set down later on.
It is intended to let the manufacturer provide for the increase or the reduction of finger dimensions, during
machining operations and according to the moisture content of the wood at the time of manufacture, so
that, for a moisture content of 11 %, the finger dimensions should be within the permitted tolerances.

ISO/R 631-1967 (E)
3.2 The fingers should have the following dimensions :
- thickness: 6, 8 and 10 mm;
the 6 mm thickness is not suitable for softwood and for the softer grades of hardwood;
- width: 18 to 25 m
