 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 Organi sation 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 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 stakeholders.  
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 Standards by the Natio nal Standards Council.  DUS 1655 -2:2016

 Introduction  
This draft Uganda  Standard intends to  give specifications for ladies  open shoes. It will assist footwear 
manufacturers and merchants in getting value for their products. In addition 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 ladies’ open 
shoes

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 
manufa ctured shoes delivered  or imported . 
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 exami ned 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 numb er of footwear  pairs to be selected 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 rand om. To ensure randomn ess 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 on e order. Every rth 
pair thus counted 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 required number of pairs is 
obtained .  
For examp le 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 different 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 pi cked up from its different parts so 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, th en 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.

A4. All randomly selected footwear pairs (Table A1, Column 2) shall be inspected for visually observed 
defects, i.e.  
i) Difference in shape, design and colour.  
ii) Odd pairing and incorrect size.  
iii) Distorte d shapes.  
iv) Faulty jointing and adhesion of sole, heel, toe guard, toe cap and insole.  
v) Insole cut short.  
vi) Broken stitches and incorrect stitching.  
vii) Missing or defective eyelets/speed hooks or eyeleting/hooking.  
viii) Variations in positioning of eyelets/speed hooks.  
ix) Stiffener not centrally placed.  
x) Unfit lace.  
xi) Finish not even and unpolished.  
xii) Missing or defective buckles/buckling assembly.  
A5.  The number of defective footwear pairs shall not exceed t he permissible number given in Table A1, 
Column 3. If, however, the n umber of defective pairs exceeds the permissible number of defectives, the lot 
shall be rejected.

 A6. In case the lot has been found satisfactory for visually observed defects, sample pairs for laboratory 
testing (Table A1, Column 4) shall be taken from am ong tho se drawn (Table 1A, Column 2). The pairs shall be 
chosen at random and tested for dimensional, physical  and chemical characteristics. If the number of 
defective footwear is less than or equal to the corresponding permissible number of defectives giv en in Table 
A1, Column 5, the lot shall be declared to have met the requirements of this standard. Otherwise if the 
defective footwear pairs are more than the corresponding permissible numbers of defectives the lot shall be 
rejected .
