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 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 National Standards Council.  
This Draft Uganda Standard, DUS DEAS 863-2 : 2015 , Cut-size paper — Specification — Part 2, Photocopy 
paper , is identical with  and has been reproduced from an East African  Standard , DEAS 863-2: 2015, Cut-size 
paper — Specification — Part 2, Photocopy paper , and is being proposed for adoption  as a Uganda Standard.  
Wherever the words, “ East African Standard" appear, they should be replaced by "Uganda Standard."

 Foreword 
Development of the East African Standards has been necessitated by the need for harmonizing requirements 
governing quality of products and services in the East African Community. It is envisaged that through 
harmonized standardization, trade barriers that are encountered when goods and services are exchanged 
within the Community will be removed.  
In order to achieve this objective, the Community established an East African Standards Committee mandated 
to develop and issue East African Standards.   
The Committee is composed of representatives of the National Standards Bodies in Partner States, together 
with the representatives from the private sectors and consumer organizations. Draft East African Standards 
are circulated to stakeholders through the National Standards Bodies in the Partner States. The comments 
received are discussed and incorporated before finalization of standards, in accordance with the procedures 
of the Community. 
East African Standards are subject to review, to keep pace with technological advances. Users of the East 
African Standards are therefore expected to ensure that they always have the latest versions of the standards 
they are implementing .  
This Draft East African Standard, DEAS  863-2, was prepared by Technical Committee EASC //TC/065 Paper 
and paper products .The Committee is composed of representatives from National Standards Bodies, 
regulators and academia, together with the representatives from the private sector and consumer 
organizations in Partner States.

The style of the package shall be such as to provide uninterrupted (step less) flat surface in the top and 
bottom of the pack. 
6.2 Labelling 
The following shall be marked legibly and indelibly on the wrapping of each ream and on each box: 
a) The name and physical address of the manufacturer or local distributor and registered trade mark,; 
b) The name of the product; 
c) The size designation of the paper; 
d) The number of reams in each pack; 
e) Number. of sheets in each ream  
f) The grammage of the paper; 
g) The colour of the paper, if other than white. 
7 Sampling and compliance with the specification 
7.1 Sampling 
7.1.1  Sampling of Package. To determine whether the packing and marking requirements of the standard 
with respect to package are met, take at random from the lot the number of package given in Table 3, 
appropriate to the lot size. 
If the package are on pallets, take as nearly as possible the same number of package from each pallet to 
make up the total number of package required.  Deem the samples so taken to represent the lot for the 
respective properties.

* In deciding the number of units to be selected round down to the nearest whole number.  
 
7.1.2  Sampling of Reams and Paper  — To determine whether the requirements of the standard with 
respect to reams and paper are met, after inspection of the package sampled in accordance with 7.1.1 , take at DRAFT UGANDA STANDARDDEAS 863-2:2015 
© EAC 2014  – All rights reserved  5 
 random a ream from each of five of the package sampled; or if fewer than five package are sampled, take a 
ream from each of them and deem the samples so taken to represent the lot for the respective properties. 
7.2 Compliance with the Specification 
The lot shall be deemed to comply with the relevant requirements of the standard if 
a) after inspection of package for packing and marking, not more than one defective is found, 
b) after inspection of the reams for packing and marking not more than one defective is found, 
c) after inspection of the paper for defects, not more than five defects are found, and, 
d) after testing in accordance with 4.2.2 , no defect is found. 
8 Inspection 
8.1 Inspection of Package   — Visually examine each of the corrugated board package sampled in 
accordance to 7.1.1  for compliance with the packing and marking requirements and report the results for each 
box. 
8.2 Inspection of Reams  —Visually examine each of the reams sampled in accordance with 6.1 and 6.2 
for compliance with the packing and marking and report the results for each ream. 
8.3 Inspection of Paper  — Open a ream and immediately remove from about the centre of the ream, the 
number of sheets required for the determination of moisture content. 
Take all reasonable precautions to avoid detectable change in moisture content of the sampled sheets. 
Afterwards count the remaining number of sheets in the ream, add the number removed, and report the total 
number of sheets in the ream. From the remaining sheets in the ream, take at random 50 consecutive sheets 
and inspect both sides for 
a) compliance with the requirements of 4.1, 
b) the machine direction. 
Report the number of defects found. Repeat this procedure with the other ream samples. Report the total 
number of defects found.
