 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) and  
(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 T echnical 
Committee is established to deliberate on standards in a given field or area and consi sts of key stakeholders 
including 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 recom mending the draft standards 
for approval and declaration as Uganda Standards by the National Standards Council.

 Introduction 
A tee-shirt (or T-shirt) is a shirt with short sleeves, round neck, put on over the head,  usually without 
pockets (though terms such as long sleeved T-shirts and sleeveless T-shirts  are sometimes used, 
suggesting that T-shirt by itself has a more general meaning) 
T-shirt was originally used as undershirt. This is still done,  but it is also worn as the only  clothing on the 
upper  part of the body (except that women often wear a bra under  it). The  length varies, but it typically 
reaches the waist. One fashion is an “oversized ” T-shirt, a more  recent trend is tight and short T-shirt for 
women that frequently show part of the lower  abdomen with the belly button. T-shirt fashions include 
styles for men and women and styles  for all age groups including baby, youth and adult sizes. T-shirts 
are decorated with text  and/or pictures 
T-shirts are manufactured by the textile industry using the jersey stitch knitting method.  Cotton, 
polyester or a mix of the two fibres can be used commercially to produce the fabric

Compliance of a lot 
The sampling procedure given below shall give desired protection to the buyer and seller  provided that 
the lot submitted for inspection is homogeneous. To achieve this, the manufacturer shall maintain a 
system of process control at all stages of manufacture and shall ensure that the T-shirts tendered by him

A.2.3 The number of bundles or packages to be selected shall be in accordance with table 5. One T-shirt 
shall be select ed from each bundle or package to form a sample. 
A.2.4 The bundles or packages shall be selected at random. In order to ensure randomness  of selection 
tables of random numbers may be used 
A.3 Number of tests 
A.3.1  Each T-shirt selected as in A.2.2 or A.2.3 shall be inspected for labelling and packaging  
requirements as given in clause 7 and clause 8

 Annex B  
(Normative) 
 
Method for measuring dimensions 
B.1 Procedure 
B.1.1 Lay flat and allow the T-shirt to relax, free from applied tension in the standard  atmosphere 
for at least 24 hours. Condition it until the difference between successive  measurements made at 
intervals of at least 24 h of appropriate measurements at three noted  measuring points if possible is less than 
0.25 percent at each measuring point. 
B.1.2  Take each measurement to the nearest millimetre with steel ruler resting in a dir ection parallel and 
close to the measuring points that are to be measured of the T- shirt as shown in  the figures. In case 
measurements cannot be taken by ruler, an accurate measuring tape may be used. 
B.1.3  Take the average of the three measurements obtained in B.1.2 to calculate the final  measurement
