 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 c arried 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 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 
for approval and declaration as Uganda Standar ds by the National Standards Council.  
The committee responsible for this document is Technical Committee UNBS/TC 7, Textile, Leather, Paper and Related 
Products, Subcommittee SC 1 , Textile and Related products.

Notes to purchasers  
The following  requirements shall be speci fied in tender invitations and  in each order  or contract:

 Annex  B 
(normative)  
 
Quality Verification of School Clothing  
B.1 Quality Verification  
B.1.1  When  a purchaser  requires  ongoing  verification  of the quality  of garments  produced  to the relevant  part 
of WDUS 1687 , it is suggested  that, instead  of concentrating  solely  on evaluation  of the final product,  he also 
direct s his attention  to the manufactur er's quality  system. In this connection  it should  be noted  that US ISO 
9001  covers the provision  of an integrated  quality  system.  
B.1.2  If the garments  do not bear the certification  mark  and no information  about  the implementation  of quality  
control  or testing during  manufacture  is available  to help in assessing  the quality  of a lot, and a purchaser  
wishes  to establish  by inspection  and testing  of samples  of the final product  whether  a lot (as defined  in 
B.2.1.3)  of the garments  produced  to a part (other  than DUS 1687 -1) of DUS 1687  complies  with its 
requirements,  the sampling  plan given  in B.2.2  and based  on the stated  AQL scan  be applied.(If  a different  
AQL is required,  reference  should be made to applicable  statistical  sampling tables.)  
It must be noted t hat 
a) such a sampling plan applies to fully manufactured garments only, and  
b) a lot that in terms of the plan is deemed to comply wi th the relevant part of DUS 1687 , could contain 
defective garments to an extent which may be derived from the tabulated values f or the  operating 
characteristic (OC) curves proportional to those curves permitted by the relevant acceptance numbers 
given in the sampling table.  
B.2 Sampling  and compliance with the relevant  part of DUS 1687  
B.2.1 Definitions  
B.2.1.1 Acceptable Quality L evel (AQL)  
The maximum  percentage  defective  that for the purpose  of sampling  inspection  can be considered  satisfactory 
as a process average  
B.2.1.2 defective  
A garment,  a component  of a garment,  a test sample,  a test specimen  or a set of test specimens  whose 
property  has been  determined,  that fails in one or more  respects  to comply  with the relevant  requirements  of 
the relevant  part of DUS 1687  
B.2.1.3 Lot  
Not less than 26 and not more  than 3200  garments  of the same  material(s) , colour (s), components , style and 
size designation, made  by one manufacturer,  and submitted  at any one time for  inspection  and testing   
xiv © UNBS 2017  – All rights reserved  
 B.2.2 Sampling  
Use the following  sampling  procedure  to determine  whether  a lot complies  with the relevant  part of DUS 1687 , 
and deem the samples so ta ken to represent the lot for the  respective  properties:  
a) sample  for inspection: from the lot take at random  the number  of garments  given  in column  2 of table  
B.1, relative to  the appropriate lot size  shown in column 1; and  
b) sample  for testing:  after inspecti on of the sample  taken  in accordance with ( a) above,  take from it at 
random the appropriate  number  of garments given  in column 4  of table  B.1.

B.2.3 Compliance  with the relevant  part of DUS 1687  
Deem the lot to comply  with the applicable  requirements of  the relevant part  of DUS 1687  if, 
a) on inspection  of the sample  taken  in accordance  with B.2.2(a),the  number  of defectives  found  does 
not exceed the relevant  acceptance number given  in column 3 of table  B.1, and  
b) on testing  of the sample  taken  in accordance  with B.2.2 ( b), the number  of defectives  found  does  not 
exceed the relevant acceptance  number given in column 5 of table B.1.

 Certification marking  
Products that conform to Uganda standards may be marked with Uganda National Bureau of Standards 
(UNBS) Certification Mark shown in the figure below.  
The use of t he UNBS Certification Mark is governed by the Standards Act, and the Regulations made 
thereunder. This mark can be used only by those licensed under the certification mark scheme operated by 
the Uganda National Bureau of Standards and in conjunction with t he relevant Uganda Standard. The 
presence of this mark on a product or in relation to a product is an assurance that the goods comply with the 
requirements of that standard under a system of supervision, control and testing in accordance with the 
certifica tion mark scheme of the Uganda National Bureau of Standards. UNBS marked products are 
continually checked by UNBS for conformity to that standard.
