If applicable, name of local government involved (Article 3.2 and 7.2):   
2. Agency responsible: Uganda National Bureau of Standards  
Name and address (including telephone and fax numbers, email and website 
addresses, if available) of agency or authority designated to handle comments 
regarding the notification shall be indicated if different from above:

4. Products covered (HS or CCCN where applicable, otherwise national tariff 
heading. ICS numbers may be provided in addition, where applicable): Paints and 
varnishes (including enamels and lacquers) based on synthetic polymers or chemically 
modified natural p olymers, dispersed or dissolved in a non -aqueous medium; solutions as

5. Title, number of pages and language(s) of the notified document: DUS 2002: 2018, 
Standard Test Method for Volatile Content of Coatings, First Edition. (11 page(s), in 
English)   
6. Description of content: This Draft Uganda  Standard  describes a procedure for the 
determination of the weight percent volatile content of solventborne and waterborne 
coatings. Test specimens are heated at 110 ± 5°C for 60 min. Sixty minutes at 110 ± 5°C  
is a general purpose test method based on the precision obtained with both solventborne 
and waterborne coatings.  
This test method is viable for coatings wherein one or more parts may, at ambient 
conditions, contain liquid coreactants that are volatile unt il a chemical reaction has 
occurred with another component of the multi -package system.  
Test Method D5095 for Determination of the Nonvolatile Content in Silanes, Siloxanes and 
Silane -Siloxane Blends Used in Masonry Water Repellent Treatments is the standard 
method for nonvolatile content of these types of materials. Test Methods D5403 for 
Volatile Content of Radiation Curable Materials is the standard method for determining 
nonvolatile content of radiation curable coatings, inks and adhesives. Test M ethod D6419 
for Volatile Content of Sheet -Fed and Coldset Web Offset Printing Inks is the method of 
choice for these types of printing inks.  
This test method may not be applicable to all types of coatings. Other procedures may be 
substituted with mutual ag reement between the producer and the user.
