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 amen ded. UNBS is mandated to co -
ordinate the elaboration of standards and is  
(a) a member of International Organisatio n for Standardisation (ISO),  
(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 an d 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 co mmittee 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 66-4: 2021 , Tomato products — Specification — Part 4: Tomato 
conce ntrates (paste and puree) , is identical with and has been reproduced from an East African  Standard, 
EAS 66-4: 2021 , Tomato products — Specification — Part 4: Tomato concentrates (paste and puree) , and 
adopted  as a Uganda Standard . 
The committee responsible  for this document is Technical Committee UNBS/ TC 204, Fruits, vegetables, 
tubers and processed products . 
Wherever the words, “ East African  Standard " appear, they should be replaced by "Uganda Standard ". 
This second edition cancels and replaces the first e dition  (US EAS 66 -4: 2017 ), which has been technically 
revised.

 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 Standard s 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 
organizatio ns 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 a re 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 Afric an 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 025 , Processed fruits, 
vegetable and tubers . 
This second edition cancels and replaces the first edition (EAS  66-4:2017 ), which has been technically 
revised.  
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.

Determination of the fill of the container  
A.1 Scope  
This method applies to glass containers.  
A.2 Definition  
The water capacity of a container is the volume of distilled water at 20 °C which the sealed container will hold 
when completely filled.  
A.3 Procedure  
A.3.1  Select a container which is undamaged in all respects.  
A.3.2  Weigh the filled container, ( W1). 
A.3.3  Empty, Wash, dry and weigh the empty container ( W2). 
A.3.4 Fill the container with distilled water at 20 °C to the level of the top there of, and weigh the container  thus 
filled ( W3). 
A.3.5  Calculate the water capacity of a container  
WCC (Water Capacity of the Container) = W3 - W2 
A.4 Calculation and expression of results  
Subtract the weight ( W2) found in A.3.3 from the weight ( W1) found in A.3.2 and divide the result by WCC 
found in A.3.5 and multiply by 100. Results are expressed as percentage.
