 Foreword  
Development of the East Afric an Standa rds h as been necessitated by the need for harmonizing requirements 
governing quality of products and services in East Africa. It is envisaged that through harmonized 
standardization, trade barriers which are encountered when goods and services are  exchange d wit hin the 
Community will be removed.  
In order to meet the above objectives, the EAC Partner States have enacted an East African Standardization, 
Quality Assurance, Metrology and Test Act, 2006 (EAC SQMT Act, 2006) to make provisions for ensuri ng 
standa rdiza tion, quality assurance, metrology and testing of products produced or originating in a third country 
and traded in the Community in order to facilitate industrial d evelopment and trade as well as helping to 
protect the health and safety of s ociety an d the  environment in the Co mmunity.  
East African Standards are formulated in accordance with the procedures established by the East African 
Standards Committee. The East African Standards Committee is established under the provisions of Article 4 
of the EA C SQM T Act, 2006. 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 t o stakeho lders  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.  
Article 15(1) of the EAC SQMT Act, 2006 provides that “Within six months of the declaration of an East African 
Standard, the Partner States shall adopt, without deviation from the approved text of the standard, the East 
African Standard as a national standard and withdraw any existing national s tandard w ith similar scope and 
purpose”.  
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.
