 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

(b) a contact point for the WHO/FAO Codex Alimentarius Commission on Food Standards ; and  
(c) the National Enquiry Point on TBT  Agree ment  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 
includ ing government, 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 recommending the draft standards

 Annex  A 
(normative)  
 
Determination of dimensions of dresses and skirts  
A.1 Principle  
Lay a dress or a skirt 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 for 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 sample, take one dress or skirt 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 dress or skirt  constituting the test sample. La y 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 given 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  DUS 1970 -4: 2021
