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 1 34:2018 , Cold rolled steel section – Specification , is identical with 
and has been reproduced from an East African Standard, EAS 1 34:2018 , Cold rolled steel section – 
Specification , and is being proposed for adoption as a Uganda Standard. 
This standard was developed by Mechanical engineering and metallurgy Standards Technical Committee 
(UNBS/TC 4).  
This third edition cancels and replaces the second edition (US EAS 134:2013), which has been technically 
revised. 
Wherever the words, “ East African Standard " appear, they should be replaced by "Uganda Standard." PUBLIC REVIEW DRAFT    DEAS 134

 PUBLIC REVIEW DRAFT    DEAS 134 
 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.

5 Compound sections  
Compound sections may be formed by suitably connecting two or more simple sections. For example, an 'I' 
section can be made from two channels back- to-back, a tube from two inwardly lipped channels lip- to-lip, a 'T" 
from two angles, etc. Methods of joining sections are specified in ISO 14347.  
Section properties of compound sections may be calculated using the properties of simple sections.  
Compound sections shall be flush at matching joints within 2.0 mm.

Lo is the gauge length;  
e) the width of the test piece shall not be less than 6 mm, unless the product width precludes use of wider 
pieces; and

Each piece shall be indelibly and legibly marked /printed at least once in every 6 meters length with the following 
i) Manufacturer’s name and/ or registered trademark  
ii) The outside dimension  
iii) Nominal thickness  
iii) The steel grade
