Foreword  
 
Kenya Bureau of Standards is a national standards body (NSB). The work of preparing Kenya 
Standards is normally carried out through natio nal technical committees. Each member body 
interested in a subject for which a technical committee 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 su bject 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 fol lowing documents:  
  
AS/NZS 4443, Office panel systems - Workstations  
 
The assistance derived from these publications is hereby acknowledged.

Kenya Standard  
Furniture – Test Methods  
Part 7:  
Drop Test  
 
 
1 SCOPE   
This Kenya Standard  sets out a  method of determining the ability of the desk to withstand impact on 
the legs or on closed base or plinth.  
 
NOTE: KS 2817  specifies the compliance requirements.  
 
2 PRINCIPLE   
The desk is raised and dropped in order to test its ability to withstand impact on the legs or base.  
 
3 APPARATUS   
The following apparatus shall be required:  
(a) Floor consisting of concrete covered with vinyl tiles.  
(b) For the pull test - 
(i) pulley;  
(ii) cable;  
(iii) weight sufficient to pull the drawer to full extension; and  
(iv) load equi valent to 0.004 kg/cubic cm of drawer volume.  
 
4 PROCEDURE  
(a) If applicable set the adjustable features at the midpoint of adjustment.  
(b) Raise one end of the unloaded desk so that the bottom of the glides or castors are 250 mm off 
the floor or at the balance po int, whichever is lower (see Figure 1).  
(c) Release the end of the long axis of the desk being tested and allow it to free fall to the floor .  
(d) Examine the desk. If the test meets the acceptance level, the other end of the desk shall be 
tested.  
 
5 PROCEDURE -PULL TEST   
Measure the pull force individually on the top drawers and file drawer (if fitted) as follows:  
(a) Ensure all drawers and roll -out shelves are loaded uniformly with 0.0046 kg/cubic cm and secure 
the desk in place.  
(b) Attach a limp cable to the center of t he pull area, extending in the same horizontal plane over a 
pulley on the test equipment.  
(c) Apply a weight to the loose end of the cable that will open the drawer or roll -out shelf to its full 
extension. If an anti -rebound is used, the weight to overcome the  anti-rebound shall be recorded.  
(d) Apply the weight required to open the drawer to full extension with the drawer past the anti -
rebound.  
(e) Record the weight (For Illustration of this pull test, see Part 1) . 
 
6 TEST REPORT   
The following information shall be re ported.  
(a) Whether there was structural breakage or loss of serviceability particularly that could cause injury 
to a user.  
(b) Whether the pull force or weight to overcome the anti -rebound exceeded 4.1 kg   
(c) Type of desk tested.  
(d) Test equipment and test report must be reproduced in full.  
(e) The date if test.  
(f) The name and address of the testing authority.  
(g) Reference to this test method, i.e. , KS 2819 -7:2018 , drop test .
