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 857: 2015, Specification for carbon paper, is identical with and has been reproduced from an East African Standard, DEAS 857: 2015, Specification for carbon paper, and is being proposed for adoption as a Uganda Standard.

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. This Draft East African Standard, DEAS. 857:2015., was prepared by Technical Committee EASC//TC/065 Paper and paper products .The Committee is composed is of representatives from National Standards Bodies, regulators and academia, together with the representatives from the private sector and consumer organizations in Partner States.
