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 Organisati on for Standardisation (ISO);   
(b) a contact point for the WHO/FAO Codex Alimentarius Commission on Fo od Standards;  and  
(c) the National Enquiry Point on TBT Agre ement 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 344:2021 , Exercise books and related items — Specification , is 
identical with and is being  reproduced fro m a Draft East African  Standard, DEAS 344:2021 , Exercise books

 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.  
The Community has established an East African Standards Committee (EASC) mandated to develop and 
issue East African Standards (EAS).  The Committee is composed of representatives of the National 
Standards Bodies in Partner States, together with the representatives from the public and private sector 
organizations in the community .  
East African Standards are developed through Technical Committees that are representative of key 
stakeholders including government, academia, consumer groups, private sector and other interested parties. 
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 Principles and procedures for development of East African Standards. 
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 .  
The committee responsible  for this document is Technical Committee EASC/TC 065, Paper and paper 
Products. 
Attention is drawn to the possibility that some of the elements of this document may be subject of patent 
rights. EAC shall not be held responsible for identifying any or all such patent rights. 
This second edition cancels and replaces the first edition (EAS 344:2004), which has been technically revised. 
The main changes compared to the previous edition are as follows:  
— The title has been changed from “Exercise books —  Specification” to “Exercise books and related 
items — Specification”  
— The text of the standard has been expanded to cater for several types and sizes of exercise books 
and related items
