 Foreword  
This Kenya Standard was prepared by the Paper and paper products Technical Committee under the guidance 
of the Standards Projects Committee, and it is in accordance with the procedures of the Kenya Bureau of 
Standards  
Bed made from corrugated fibre board are manufactured to address the shortage of beds in  isolation centres 
such as hospitals and homes . Paper and board  manufactures have come up with a recyclable, lightweight and 
cost-effective solution of bed s made of corrugated fibreboard . 
The bed can withstand up to 300 kgs, and can be assembled easily. The bed can also be sanitized and withstand 
daily moping.  
This standard shall be useful to manufacturers of beds made from corrugated fibre  boards , hospitals, isolation  
centers, other relev ant stakeholders.  
The parameters covered in the Standard, include the, the grammage, dimension, load capacity, moisture  
content among others . 
In the preparation of this Kenya standard, reference was made to the following document:

3.6 
flat crush  
maximum crushing force, applied perpendicular to the surface of the fluting structure, sustained before complete 
collapse of the structure
