Foreword  
Kenya Bureau of Standards is a national standards body (NSB). The work of preparing Kenya Standards 
is normally carried out through national technical committees. Each member body interested in a subject 
for which a technical commit tee has been established has the right to be represented on that committee. 
National organizations, governmental and non -governmental, in liaison with KEBS, also take part in the 
work.  
Kenya Standards are drafted in accordance with the rules given in the KS ISO/IEC  Directives, Part  2. 
The main task of technical committees is to prepare National Standards. Draft Kenya Standards adopted 
by the technical committees are circulated to the technical committee members for balloting. Publication 
as a Kenya Standar d requires approval by at least 2/3 of the members casting a vote.  
Attention is drawn to the possibility that some of the elements of this document may be the subject of 
patent rights. KEBS shall not be held responsible for identifying any or all such pate nt rights.  
This Kenya Standard was prepared by Technical Committee KEBS/TC  164, Furniture . 
During the preparation of this standard, reference was made to the following documents:  
  
AS/NZS 4443, Office panel systems - Workstations  
 
The assistance derived fr om these publications is hereby acknowledged.

Furniture – Test Methods  
Part 4:  
Outs top of desk drawers to withstand an abnormal pull -out 
 
1 SCOPE   
This Kenya Standard sets out a method of evaluating the ability of the outstops of desk drawe rs to 
withstand an abnormal pull -out force.  
 
NOTE: Clause KS 2817: 2018  specifies the compliance requirements.  
 
2 PRINCIPLE   
A specified load and force are applied to the drawers to test the outstops and connections.  
 
3 APPARATUS  The following apparatus is  required:  
(a) Load of 80 g per linear millimeter  
(b) Cable.  
(c) Pulley.  
(d) 4.5 kg weight.  
(e) Static loads for drawers specified in Table 1. 
 
4 PROCEDURE  (see Figure 1)  
The test procedure shall be as follows:  
(a) Place the unit in its normal operating position.  
(b) Load the drawer  uniformly, as specified in Table 1. For drawers with an inside clear width in excess 
of 330mm, with the exception of those drawers with a front height of up to and including 100 mm, the 
test loads shall be proportionately higher in accordance with the fol lowing formula (all units in 
millimeters):  
 
W X L  = test load of drawer  
330 
 
Where  
 W = actual inside clear width dimension of drawer  
 L = test load per draw front height.  
Where the drawers are supported, load the work surface uniformly at 80 g per linear millimeter, distributed 
and centered along a line 200 mm in from the front edge.  
 
(c) Attach a cable to the center of the pull area and extend it horizontally to pulley. The opposite end of 
the cable shall extend downward and have a 4.5 kg weight attached to t he free end.  
(d) Hold the drawer in a closed position and release the weight, causing the drawer to open rapidly, The 
weight shall be restrained after falling 80% of the drawer travel.  
(e) Repeat this procedure 5 times.  
 
5 TEST REPORT   
The following information sh all be reported:  
(a) Whether the unit showed structural failure, deformation or loss of serviceability.  
(b) Whether the mounting hardware or outstops were intact.  
(c) Type of desk tested  
(d) Test equipment and test method title or name.  
(e) A notation that the test report mus t be reproduced in full.  
(f) The date of test.  
(g) The name and address of the testing authority.  
(h) Reference to this method, i.e. KS 2819 -4:2018, Outstop test for drawers supported by work surface.
