Uganda National Bureau of Standards (UNBS) is a parastatal under the Ministry  of Tourism, Trade and 
Industry established under Cap 327, of the Laws of U ganda. UNBS is mandated to co-ordinate the elaboration 
of standards and is  
(a) a member of International Organisation for Standardisation (ISO) and  
(b) a contact point for the WHO/FAO Codex A limentarius Commission on Food Standards, and  
(c) the National Enquiry Point on TBT/SPS Agr eements of the World Trade Organisation (WTO). 
The work of preparing Uganda Standards is carried out through Technical Committees. A Technical 
Committee is established to deliberate on standards in a gi ven field or area and consists of representatives of 
consumers, traders, academician s, manufacturers, governme nt and other stakeholders. 
Draft Uganda Standards adopted by the Technical Committ ee are widely circulated to stakeholders and the 
general public for comments. The committee reviews the comments before recommending the draft standards 
for approval and declaration as Uganda Standards by the National Standards Council. 
This Final Draft Uganda Standard, FDUS EAS 184: 2011 , Emulsion paints  — Specification, is identical with  
and has been reproduced from an East African Standard, EAS 184: 20 11, Emulsion paints  — Specification,  
and is b
eing proposed for adoption as a Uganda Standard.  
This standard was developed by the Chemicals and env ironment Standards Technical Committee (UNBS/TC 
5).

Development of the East African Standards ha s been necessitated by the need for harmonizing 
requirements governing quality of products and services in the East African Community. It is envisaged that 
through harmonized standardization, trade barriers that are encountered when  goods and services are 
exchanged within the Comm unity will be removed.  
eve this objective, the Community established an East African Standards Committee 
 Partner States, together 
ate sectors and consumer organizations. Draft East African Standards 
r States. The comments 
nce with the procedures 
ances. Users of the East 
dards are therefore expected to ensure that they always have the latest versions of the 
standards they are implementing .

1.1 This standard specifie s the requirements for three grades of  emulsion paint that are based on 
water phase for application over interior plaster or other masonry 
rade. These three grades are suitable for both interior and

ncrete, or bituminous 
substrates. In such cases, this standard will only apply to the paint as supplied, not to its end-use.
