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.

ii100 per cent cotton fabrics are widely used for making bedsheets. To perform to the satisfaction of users, the fabrics and the bedsheets made therefrom must meet the minimum requirements expected for this purpose. This East African Standard specifies these minimum requirements.
In the preparation of this standard, reference made to:
BS 5815-1:1989, Specification for sheeting, sheets and pillowslips

This East African Standard applies to finished bedsheets made from:
1The fabric shall be 100 per cent cotton and shall comply with the requirements of EAS 227. This shall be determined in accordance with EAS 255.
The fabric properties shall be as specified in Table 1.
The fabric selvedges when visually examined shall be straight and firm.
The fabric used for the manufacture of bedsheets shall be of grade not lower than B in accordance with EAS 253-1.
The colourfastness of the coloured fabrics shall be as specified in Table 2.

The sewing thread shall be 100 per cent cotton of ticket number 50 complying with EAS 250-1. The thread shall be of the same colour as the bedsheet and in the case of coloured bedsheet, of the same colourfastness — see Table 2.
A bedsheet shall have a minimum of 2 cm end-hems. A minimum of 0.5 cm of the raw edges shall be turned in.
A bedsheet of width more than 155 cm may be joined on one side or both sides. No bedsheet shall have more than two seams within the body. The seams shall be neatly turned in so that no raw edges are exposed and stitched with a stay seam. The ends of all stitching threads shall be trimmed and loose ends removed.
