6. Description of content: This Draft Uganda  Standard  covers the determination, without 
reference to a material paint standard, of the hiding power of air dry coatings with Y 
tristimulus values greater than 15%. With appropriate modification, it  can also be used to 
test baking finishes. The values stated in SI units are to be regarded as standard. No other 
units of measurement are included in this standard.  
7. Objective and rationale, including the nature of urgent problems where 
applicable: Prevention of deceptive practices and consumer protection; Protection of 
human health or safety; Harmonization
