This European Prestandard (ENV) was approved by CEN on 7 April 2001 as a prospective standard for provisional application.
The period of validity of this ENV is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the ENV can be converted into a European Standard.
CEN members are required to announce the existence of this ENV in the same way as for an EN and to make the ENV available promptly
at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the ENV) until the final
decision about the possible conversion of the ENV into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece,
Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and United Kingdom.

3 General test conditions
If chairs or tables in a range of size marks are manufactured, all having similar design details and
geometry, it is only necessary to carry out the complete test programme on the largest chair/table in the
range, plus additional drop test and seat impact test on the smallest chair in the range.
In the event of failure in any of the largest or smallest chairs/tables in the above test programme, it is
necessary to carry out the complete test programme on each chair/table size mark individually.
4 Safety requirements
In order to minimize the risk of personal injury or damage to clothing, the following requirements apply:
a) all edges and corners, with which the user may come into contact during normal use, shall be
smooth and shall have no burrs, and shall be rounded with a minimum radius of 2 mm;
b) distances between moving parts shall always be either maximum 8 mm or more than 25 mm
and the construction shall ensure that entrapment of fingers is avoided;
c) open ends and feet of tubular components shall be capped or otherwise closed;
d) parts shall not be detachable without the use of an appropriate tool;
e) parts which are lubricated shall be covered in order to avoid staining;
f) the reflection of the working surface of tables shall be maximum 45 determined in
o
accordance with ISO 2813 at 60 ;
g) the tristimulus value of the working surface of tables shall be between 15 % and 75 %
determined in accordance with ISO 7724-2;
h) chairs shall not overturn when tested as specified in 5.1.1, 5.1.2 and 5.1.3;
i) chairs shall show no structural failure which can affect safety
