4 General test conditions
4.1 Preliminary preparation

Before any of the tests are commenced, the item shall be old enough to ensure that it has developed its

full strength.

The unit(s)/component(s) shall be tested as delivered. The unit(s)/component(s) shall be assembled

and/or configured according to the instructions supplied. Unless otherwise stated, the most adverse

configuration shall be used for each test. If mounting or assembly instructions are not supplied, the

mounting or assembly method shall be recorded in the test report. Fittings shall be tightened before

testing and shall not be retightened unless specifically required in the manufacturer’s instructions. If the

---------------------- Page: 15 ----------------------
oSIST prEN 14434:2021
prEN 14434:2021 (E)

configuration needs to be changed in order to produce the worst-case conditions, this shall be recorded

in the test report.

The tests shall be carried out in indoor conditions, but if during a test the temperature is outside the range

of 15 °C to 25 °C, the maximum and/or minimum temperature shall be recorded in the test report.

Tighten any assembly fittings before testing. Further retightening shall not take place unless it is

specifically required by the manufacturer.
4.2 Tolerances
Unless otherwise stated the following tolerances apply:
— masses: ± 0,5 % of the nominal mass;
— dimensions: ± 1,0 mm of the nominal dimension;
— angles: ± 2° of the nominal angle;
— forces: ± 5 % of the nominal force.
4.3 Test installation

For the structural tests in Clause 9, the board shall be installed according to the manufacturer's

instructions.

Wall mounted boards shall be mounted to a structure sufficiently strong and stiff to eliminate the

possibility of it affecting the results of the tests. The mounting of the structure shall be representative of

the service installation.

Where the manner of mounting is ambiguously defined, the manner of mounting shall be recorded in the

test report.
5 Test equipment
5.1 Floor surface, rigid horizontal and flat.
5.2 Wall surface, rigid, vertical and flat.
5.3 Chalk, two types of white chalk:
a) made from calcium carbonate;
b) made from calcium sulphate.
5.4 Pen, red alcohol base, acrylic tipped dry marker.
5.5 Loading pad

Loading pad (from EN 16122:2012, 5.4) which is a rigid disc 50 mm in diameter, with a flat face and a

12 mm front edge blend radius.

oSIST prEN 14434:2021
prEN 14434:2021 (E)
6 General safety requirements
6.1 All boards

All accessible edges and corners shall be rounded or chamfered and shall have no burrs. Hollow ends

shall be capped or otherwise closed.

In order to avoid shearing and squeeze, the distance between parts moving relative to each other shall

have safety distances, which shall always be less than 8 mm or more than 25 mm in any position during

movement.

a) Shear and squeeze points, which are held apart by buffers are exempt from this requirement

provided that the gap produced by the buffer is at least 25 mm.

b) For winged boards, the gap between two parts of the board is exempt from this requirement.

c) For vertically sliding boards (sash boards, to and fro boards), where there is a risk of entrapment,

the requirement is applicable except between the boards. The gap between the boards shall be at

least 25 mm.
For c) gaps of 50 mm or more are recommended.

For vertically sliding boards (sash boards, to and fro boards), there shall be at least 120 mm from the

floor to the board if no front protection is provided.

It shall not be possible to remove detachable parts inclusive end caps without the use of a tool.

No part attached to the rail system shall be detached unintentionally.
Counterweight mechanisms shall not be accessible during normal use.
It shall not be possible to operate controls inadvertently or accidentally.

If castors are provided as means of mobility, at least half of them shall be lockable.

6.2 Stability of free-standings boards
The board shall not overturn when tested according to EN 1023-3:2000, 6.1.
6.3 Dynamic stability of mobile boards

The board shall not overturn when tested according to EN 16122:2012, 11.6 in the direction/s most likely

to tip over.
7 Surface tests and requirements for whiteboards
7.1 General
There are three performance levels specified in this clause, Level 1, 2 and 3.
The minimum requirement for the writing surface is Level 1 (see also Clause 13).

The tests shall be carried out as specified in 7.2 to 7.5. Test samples shall have the same constitution as

the board to be tested, unless otherwise specified.
7.2 Ability to write and erase
7.2.1 Testing

Testing shall be carried out according to EN 438-2:2016+A1:2018, Clause 11, using CS 10 grindstone.

---------------------- Page: 17 ----------------------
oSIST prEN 14434:2021
prEN 14434:2021 (E)

Three samples shall be tested, one for 500 cycles, one for 1 000 cycles and one for 2 000 cycles.

7.2.2 Method of marking the surface

By using a pen (5.4), two parallel straight lines shall be made over the abraded area (Figure 14).

The pen shall be fixed at 45° to the surface of the board with a vertical force F of 20 N acting on the pen

(Figure 15).
