Foreword  
 
Kenya Bureau of Standards is a national standards body (NSB). The work of preparing Kenya Standards 
is normally c arried out through national 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 thi s 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, refer ence was made to the following documents:  
  
AS/NZS 4443:1997, Office panel systems - Workstations  
 
The assistance derived from these publications is hereby acknowledged.

Kenya Standard - Furniture – Test Methods  
Part 2:  
Cyclic top load test  
 
1.  SCOPE  
This Kenya Standard prescribes the test methods for cyclic top load test for free standing office furniture.  
2 APPLICATION    
This test method sets out a method of evaluating the durability of a desk to withstand cyclic 
loading of the top. This test applies to primary surfaces only. 
 
This Kenya Standard covers freestanding desks such as single and double pedestal desks and extended 
units both adjustable and fixed height. It also includes tables intended for use as desks.  
 
 
NOTE: KS 2 817:2018  specifies the compliance requirements. 
  
3  PR IN C IPLE   A specified load  and  force are applied  to the desk  to test the ability of the 
desk to withstand them. 
 
4       AP PARATUS    The following apparatus a r e  required:  
(a)     Test platform. 
(b)     Load that is equivalent to 0.00046 kg/cubic cm of drawer volume.  
(c)     Means of applying and measuring a 910 N force. 
(d)     Means of cycling and counting cycles. 
(e)     400 mm diameter loading pad. 
(f )      M eans of measuring in millimeters.  
(g)     For the pull test — 
   (i)   pu lley; 
   (ii)  Cable  
   (iii)weight sufficient to pull the drawer to its full extension; and  
   (iv) a load equivalent to 0.00046 kg/cubic cm of drawer volume.  
 
5    PR OC EDU R E (see Figure 1)     
The procedure shall be as follows:  
(a)     Level the desk to its normal operating position. 
(b)   S ecure  the  desk  to  the  test  platform  to  prevent  tilting  or  tipping  during  the  test 
procedure. 
(c)   L oad all drawers with 0.00046 kg/cubic centimeter of drawer volume and close for the 
duration of the test. 
(d)   Apply a 910 N force through a 400 mm diameter loading pad with the centre of the load at 
the intersection  of the centre-line and a line 230 mm from the front edge of the  desk  top,  
eased  onto  the  top,  so  that  the  top  takes  the  full  load  without  any support from the test 
equipment. 
(e)    C onduct the test at a rate of 10 cycles ±2 cycles per minute (0.17 Hz ±0.03 H z) for 
20,000 cycles.

6 PR OC EDU R E — PU LL TEST      
Measure   the p u l l  f o r c e  i n d i v i d u a l l y    on t h e  top  drawer and file drawer (if fitted), as 
follow s: 
(a)     Ensure     all     drawers     and     roll-out     shelves     are     loaded     uniformly     with 
0.00046 kg/cubic cm and secure the desk in place. 
 
(b)    A ttach a limp cable to the centre of the pull area, extending in the same horizontal plane 
over a pulley on the test equipment. 
 
7  TEST REPORT   
The following information shall be reported:  
(a) Test method title or name.  
(b) Test equipment  
(c) Type of desk tested.  
(d) The name and a ddress of the testing authority.  
(e) Whether the desk showed structural damage or deformation.  
(f) Whether the pull force or weight to overcome the anti -rebound exceeded 4.1 kg.  
(g) A notation that the test report must be reproduced in full.  
(h) The dat e of test.  
(i) Referenc ing to this test method, i.e. KS 2819 -2:2018, part 1 , Top load cyclic test .
