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 1048: 2021 , Medical tissue paper towel  — Specification , is identical 
with and has been reproduced from a Draft East African Standard, DEAS 1048: 2021 , Medical tissue paper 
towel   — Specification , and is being proposed for adoption as a Uganda Standard. 
The committee responsible for this document is Technical Committee UNBS/TC 7,  Textiles, Leather, Paper 
and related products , Subcommittee SC 3, Paper and paper products.  
 
Wherever the words, “ East African Standard " appear, they should be replaced by "Uganda Standard."

 Foreword  
Develop ment 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 enc ountered 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 represen tatives 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 k ey 
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 develop ment of East African Standards.  
East African Standards are subject to review, to keep pace with technological advances. Users of the E ast 
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.

 Annex  A 
(normative)  
 
Determination of perforation ratio  
A.1 Apparatus  
Appropriate measuring device, such as a metre rule graduated with 0.5 mm interval  
A.2 Procedure  
Using a metre ruler , measure the perforations of one perforation line. The sum of the perforations divided by 
the width of the paper gives the rati o of perforations to the width.  Measure the perf oration of five lines and take 
the mean of the ratio.   
A.3 Results  
The mean ratio shall not be less than that specified in Table 1.
