  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 whe n 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 .  
DEAS 1180 :2023  was prepared by Technical Committee EASC/TC 042, Production and general 
engineering .  DEAS 1180:2023

  DEAS 1180:2023  
                               
  6.2.2 Procedure   
Insert the taper gauge into the eye of each tool in the sample and note the position of the eye in relation to the 
end faces of the taper gauge. Check for compliance with the requirement of 4.4.   
6.3 Hardness test   
Determine the hardness of each tool in the sample by using the relevant method described in ISO 6508 -
1. Take at least three reading s on each surface. Check for complianc e with the requirements of 4.6.  
 
6.4 Composition of material  
Using any recog nized method of analysis, test each tool in the sample for compliance with the relevant 
requirements of 4.2.  WD/TC 035/00 5/2023
