 Foreword  
Uganda National Bureau of Standards (UNBS) is a parastatal under the Ministry of Trade , Industry and 
Cooperatives established under Cap 327 , of the Laws of Uganda , as amended .  UNBS is mandated to co -
ordinate the elaboration of standards and is  
(a) a member of International Organisation for Standardisation (ISO) ;  
(b) a contact point for the WHO/FAO Codex Alimentarius Commission on Food Standards ; and  
(c) the National Enquiry Point on TBT  Agreement  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 given field or area and consists of key stakeholders 
including governme nt, academia, consumer groups, private sector and other interested parties.  
Draft Uganda Standards adopted by the Technical Committee are widely circulated to stakeholders and the 
general public for comments. The committee reviews the comments before reco mmending the draft standards 
for approval and declaration as Uganda Standards by the National Standards Council.  
The committee responsible for this document is Technical Committee UNBS /TC 315, Textiles and related 
products .

 Annex  A 
(normative)  
 
Determination of dimensions of shirts  
A.1 Principle  
Lay a piece of a shirt  on a flat table removing any curls and without stretching, take the measurements from 
one end to the other using a steel rule. Repeat the procedure fo r other specimens in the laboratory sample.  
A.2 Apparatus  
A.2.1  Flat table  
A.2.2  Steel rule, accuracy of at least 1 mm  
A.2.3  Calculator  
A.3 Sampling  
From a laboratory s ample, take one shirt  and subject it to conditioning prior to testing.  
A.4 Conditioning  
Condition the specimen in accordance with US ISO 139.   
A.5 Procedure  
Take each shirt  constituting the test sample. Lay it flat on a table. Remove by hand all creases and wrinkles 
without distorting it. Measure correct to the nearest 0.5 cm the dimensions g iven in Table 2 or Table 3.  
Repeat the procedure for any other specimen that may be required in the laboratory sample.  
A.6 Calculation and expression of results  
Take the average of the individual measurements and double the result to obtain the dimensions
