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 committe e 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 Standard 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 patent  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:  
  
IS 3663: 1993: Dimensions of tables and Chairs for office purposes  
 
The assis tance derived from these publications is hereby acknowledged.

Kenya Standard  
Furniture – Test Methods  
Part 3:  
Lock test for drawers supported by work surface  
 
1 SCOPE   
This Kenya Standard sets out a method of demonstrating that the locking m echanism will provide security 
for the contents of the drawer.  This Kenya Standard covers freestanding desks such as single and double 
pedestal desks and extended units both adjustable and fixed height.  
 
 
NOTE: KS 2817: 2018  specifies the compliance requi rements.  
 
2 PRINCIPLE   
A specified load and force are applied to the drawers to test the locking mechanism.  
 
3 APPARATUS   
The following apparatus is required:  
(a) Load of 80g per linear mm  
(b) Means of applying and measuring a 222 N. force.  
(c) The static loads for dr awers specified in Table C1.  
(d) Means of measuring in millimeters.  
 
4 PROCEDURE  (see Figure 1)  
The procedure shall be as follows:  
(a) Place the unit in its normal operating position.  
(b) Load the drawers uniformly, as specified in Table C1. For drawers with an insid e clear width in 
excess of 330 mm, 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 following formula (all units 
in millimeters):  
 
W X L  = test load  of drawer  
330 
 Where  
  
 W = actual inside clear width dimensions of drawer  
 L  = test load per draw front height  
 
 Where the drawers are supported, load the work surface at 80 g per linear millimeter, distributed 
 and centered along a line 200 mm in from the front edge.  
(c)   Close and lock the drawers  
(d)  Apply a horizontal outward force of 222 N at the center of the pull of the drawer.  
(e) Test each drawer one at a time.  
 
5 TEST REPORT   
The following information shall be reported:  
(a) Whether the drawer opened during the pull test.  
(b) Whether the locking mechanism deformed or did not operate normally after the test and whether any 
component was dislodged.  
(c) Type of desk tested.  KS 2819 -3:2018  
(d) Test equipment and test method title or name.  
(e) A notation that the test report must be prod uced in full.  
(f) The date of test.  
(g) The name and address of the testing authority.  
 
(h) Reference to this test method, i.e. KS 2819 -3: 2018 , Lock test for dra wers supported by work 
surface.
