iDevelopment of the East African Standards has 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 exchanged within the Community will be removed.
In order to achieve this objective, the Partner States in the Community through their National Bureaux of Standards, have established an East African Standards Committee.
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.

The width of each piece shall be as declared subject to a tolerance of +2 % or −(minus) 1 %. This shall be determined in accordance with EAS 258-1.
The length of each piece shall be as declared subject to a tolerance of −(minus) 1%. This shall be determined in accordance with EAS 258-2.
The width of each roll shall be as declared subject to a tolerance of −(minus) 1 or +2 %. This shall be determined in accordance with Clause 4 of EAS 245-1.
The length of each roll shall be as declared subject to a tolerance of −(minus) 1 %. This shall be determined in accordance with Clause 3 of EAS 245-1.
The fabric shall be rolled-up into rolls or lapped into bales of the agreed length. The rolls or bales shall be securely wrapped with suitable wrappers to prevent damage.
The following information shall be clearly marked on each roll or bale:
