 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 I nternational 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 S tandards is carried out through Technical Committees. A Technical 
Committee is established to deliberate on standards in a given field or area and consists of representatives of 
consumers, traders, academicians, manufacturers, government and other stakehol ders.  
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 
for approval and declaration as Uganda Sta ndards by the National Standards Council.

 Introduction  
This draft Uganda Standard intends to give specifications for children’s shoes ( between 2 to 6 years). It will  
assist footwear manufacturers and merchants in getting value for their products. In addi tion it will give the 
general consumers of the product bases to choose the products from an informed state.  
The main purpose of this standard therefore is to provide a basis for evaluating the quality of children’s closed 
shoes ( between 2 to 6 years) .

 ANNEX A:  
(Normative )  
SAMPLING AND CRITERIA FOR CONFORMITY  
A1. DEFINITIONS  
A1.1 Lot — All footwear pairs in a consignment belonging to the same pattern/design and batch of 
manufactured shoes delivered  or import ed. 
A1.2 Defect — A fault or failure of a footwear pair to meet the requirements of this standard.  
A1.3 Defective Footwear — A footwear pair with one or more defects as mentioned in this standard.  
A2. SCALE OF SAMPLING  
A2.1 Samples shall be selected and ex amin ed for each lot separately for ascertaining the conformity of the 
footwear to the requirements of this standard.  
A2.2 Footwear shall be considered to be of different lots if they differ in shape and design.  
A2.3 The number of footwear  pairs to be selec ted from any lot shall depend on the size of the lot and shall 
be in accordance with Columns 1 and 2 of Table A1.  
A3. METHOD OF SELECTION  
A3.1 Footwear to be selected from the lot shall be chosen at random. To ensure randomness the 
procedure in A3.2 shall be used.  
A3.2 When the footwear pairs in a lot are not packed in a number of cases (boxes), the sampling shall be 
as follows:  
Starting from any footwear pair in the lot, count the pairs as 1 , 2, etc---up to r and so on in one order. Every rth 
pair thus cou nted shall be withdrawn to constitute a sample (r is the integral part of N/n where N is the lot s ize 
and n is the sample size). This procedure shall be stopped as soon as the require d number of pairs is 
obtained.  
For example if a sample of 125 pairs is to be selected from a lot of 3,000 pairs , compute r as equal to integral 
part of 3,000/125=24. Starting from any pair, the footwear shall be counted in one order and every 24th pair 
shall be withdrawn.  
A3.3 When the footwear pairs in a lot are packed in diff erent cases ( boxes), a suitable number of boxes 
(not less than 30 per cent of  the total boxes in the lot) shall be first chosen at random.  For each of the boxes 
so chosen, an approximately equal number of pairs shall be picked up from its different parts s o as to obtain 
the required number of pairs.  
For example, if a lot consists of 1,000 pairs of footwear packed in 50 boxes each containing 20 pairs, choose  
more than 15 boxes at random. If it is decided to open 20 boxes, then 4 pairs shall be picked up from  different 
parts of each of the 20 bo xes to give a total of 80 pairs  as specified in Table 1.
