 Foreword  
 
 
This Part 2 of KS 779  has been prepared by the Technical Committee on Textile Floor Coverings and 
Furnishings  under guidance of the Standards Projects Committee, and it is in accordance with the 
procedures of the Kenya Bureau of Standards.  
 
 
Part 2 of th is standard deals with sisal carpets woven without pile to be used for covering floors. It 
specifies minimum requirements that will ensure good performance of sisal carpets during normal use.  
 
The need to revise this standard was identified to address the following issues:  
 
Test method for color fastness to light has been updated.  
Test method for color fastness to washing  has been updated.  
Test method for color fastness to rubbing has been updated.  
Test method for thickness has been updated.  
Standard for definition has  been updated.  
Test method for dimensional changes have been updated.  
Test method for wear has been updated.  
 
This Second edition cancels and replaces  the First edition (KS 779 -2:1990 ) which has been technically 
revised.  
 
In the preparation o f this standard reference was made to the following document:
