European foreword
This document (EN 13647:2021) has been prepared by Technical Committee CEN/TC 175 “Round and
sawn timber”, the secretariat of which is held by AFNOR.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by October 2021, and conflicting national standards shall
be withdrawn at the latest by October 2021.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 13647:2011.
Compared with EN 13647:2011, the following modifications have been made:
— in lipping measuring;
— in dimensions measuring: thickness of the element, thickness of the top layer, depth and width of the
groove, thickness and width of the tongue.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,
Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of North
Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United
Kingdom.
Introduction
This document is one of a series of standards specifying requirements and test methods for wood flooring
and wood panelling and cladding.
The measurements should be carried out as specified in this document or with any other equipment or
principles giving at least the same accuracy.
1 Scope
This document specifies methods of measuring the geometrical characteristics of wood flooring and
wood panelling and cladding elements.
This document does not specify sampling, which is intended to be found in the product standards or test
methods and it does not apply to elements which are installed.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 13756:2018 apply.

4 Principles
4.1 General
The measurements shall be carried out only if relevant, taking the product standards into account.
4.2 Dimensions
The dimensions are determined by measuring any characteristic defined in the product standard and
with appropriate tools.
4.3 Angles
Determine square angles by measuring the distance (maximum value) between an edge of the element
and the side of a square whose other side is in line with an adjacent edge of the element.
Determine other angles by the use of a protractor.
4.4 Warp
4.4.1 Cup
Determine cup by measuring, at the middle of the width of the element, the distance separating the face
of the element from the straight reference line joining the top arises of the edges of the element, see
Figures 1 and 2.

4.4.2 Bow
Determine bow by measuring, at the middle of the length of the element, the distance separating the face
of the element from the straight reference line joining the end top arises of the element, see Figures 3
and 4.
If the maximum bow is not in the middle of the length, the measurement can be carried out at the
appropriate place and this should be mentioned in the report.

For practical reasons, convex bow may be measured in the same way on the back of the element.

4.4.3 Spring
Determine spring by measuring, at the middle of the length of the element, along the lengthwise edges of
the element, the distance separating one edge from the straight reference line joining the two arises of
that edge, see Figure 5.
NOTE The measurement is usually carried out on the edge bearing the groove.

4.5 Lipping
Determine lipping by measuring the difference in the levels of the face of two adjacent elements when
they are assembled together, see Figure 6.

5 Equipment
5.1 General
The equipment specified in this document is given as an indication. Any other equipment providing the
same results with at least the same accuracy may be used.
5.2 Equipment to measure the dimensions
5.2.1 Calliper
It shall have an accuracy of ± 0,05 mm.
If used to measure the characteristics of tongue and groove profiles, it shall have a built-in depth rod.
It shall also have a useful measuring length corresponding to the width of the elements to be measured.
5.2.2 Micrometer
It shall have a limit deviation of ± 0,05 mm and two parallel flat circular feelers having a diameter of
(10 ± 1) mm.
It shall be used for measurement of total thickness.
NOTE 1 For the measurement of top layer thickness, the device mentioned in 5.2.4 and the procedure described
in 6.5.9 are suitable.
NOTE 2 Other similar optical devices, e.g. microscope are also suitable to be used.
5.2.3 Graduated rule
It shall be used wh
