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 412-3:2018 , Steel for the reinforcement of concrete — Part 3 : 
Welded bars , is identical with and has been reproduced from an East African Standard, EAS 412-3:2018 , 
Steel for the reinforcement of concrete — Part 3 : Welded bars , 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 second edition cancels and replaces the first edition (US EAS 412-3:2013), which has been technically 
revised. 
Wherever the words, “ East African Standard " appear, they should be replaced by "Uganda Standard." PUBLIC REVIEW DRAFT

 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.

 7 Testing of mechanical properties  
 
The testing shall be done on wires taken from the fabric in the delivery condition. The test piece shall not be 
worked before testing but it may be heated to 100 “C and then cooled freely in air to the test temperature.  
 
 
7.1 Tensile test

length of five times the nominal diameter and shall have at least one crossing wire. The free distance between 
the grips shall be at least 20 times the nominal diameter, and not less than 180 mm. 
 
In fabric with twin wires, the wire which is not under test shall be cut off approximately 20 mm from the joints.

 shown in figure2 shall be cut from the fabric. In addition to the weld to be tested, the test piece may have one 
or more welds, depending on the spacing. 
For fabric with single wires in both directions, the thicker wire shall be used as the pulling wire. 
For fabric with twin wires, one of the twin wires shall be the pulling wire. The other twin wire is cut off 
from the crossing wire without affecting the weld under test. 
Test pieces previously subjected to tensile testing -may be used for the weld shear test, provided that the necking 
at the fracture is clear of the weld zone

unit 
 
 
10.3.3 Evaluation of the results 
 
 
10.3.3.1 Inspection by variables 
 
For properties, which are specified as characteristic values, the following shall be determined:

b) the mean value m15 (for n = 15); 
 
      c) the standard deviation s15, (for n = 15). 
The test unit corresponds to the requirements if the condition stated below is fulfilled for all properties: 
 
M15 – 2.33 x s15 ≥  f k 
where 
f k is the required characteristic value; 
 
2,33 is the value for the acceptability index k for n = 15 for a failure rate of 5 %A0 
ρ, = 095) at a probability of 90 % (1 - α = 0.90).  
 
If the condition stated above is not fulfilled, the index 
 
 
is determined from the test results available. Where k’ > 2, testing can be continued. In this case 45 additional

10.3.3.2 Inspection by attributes 
 
When testing properties specified as maximum or minimum values, all results determined on the 15 test pieces 
shall comply with the requirements of this part of East Africa Draft Standard. In this case the test unit shall be 
considered to comply with the requirements. 
 
The tests can be continued when at most 2 results not conforming to conditions occur. In this case 45 
further test pieces from various fabrics in the test unit shall be tested, so that a total of 60 test results are 
available’. The test unit complies with the requir ements if at most 2 of the 60 results do not conform to the 
conditions. 
 
 
 
10.4 Verification of guaranteed minimum values 
 
Tests shall be carried out according to the following.  
 
Tests shall be carried out according to the following. 
 
- For the purpose of testing, the delivery shall be subdivided into test units with a maximum mass of 50 t or a 
fraction thereof. Each test unit shall consist of products of the same nominal diameter from the same production 
lot. 
 
-For each mechanical property’ specified, one  test shall be carried out for each-test unit. Each individual test 
result shall meet the requirements specified in clause 6. 
 
- If any test result does not meet the requirements, retests may be carried out, according to IS0 404 
 
-the manufacturer shall submit a test report stating that products of the delivery satisfy the mechanical properties 
specified in clause 6 and a confirmation that the other requirements of this part of IS0 6935 are fulfilled. 
 
 
 
11 Test report 
The test report shall contain the following information: 
 
a) works producing the welded fabric; 
 
b) designation of the fabric according to clause 8; 
 
c) number on the bundle; 
 
      d) name of the organization carrying out the test, if appropriate; 
 
e) date of testing; 
 
f) mass of the test unit; 
 
g) test results.
