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 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 ensuring standardization, quality assurance, metrology and testing of products produced or originating in a third country and traded in the Community in order to facilitate industrial development and trade as well as helping to protect the health and safety of society and the environment in the Community.
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 EAC SQMT 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 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.
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 standard with 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.

Sorghum grains — Specification
This East African Standard specifies the quality and grading requirements and methods of sampling and test for sorghum grains of varieties (cultivars) grown from Sorghum bicolor (L.) Moench intended for human consumption, i.e., ready for its intended use as human food, presented in packaged form or sold loose from the package directly to the consumer. It does not apply to other products derived from sorghum grains.

For the purpose of this East African Standard, the following definitions shall apply
Grain that, before the removal of dockage, consists of 50 % or more of whole kernels of sorghum (Sorghum bicolor (L.) Moench) excluding non-grain sorghum and not more than 10.0 % of other grains for which standards have been established.
pieces of sorghum grain which passes through a screen having round holes of 1.8 mm in diameter
kernels, pieces of sorghum kernels, and other grains that are badly ground damaged, badly weather damaged, diseased, frost-damaged, germ-damaged, heat-damaged, insect-bored, mould-damaged, sprout-damaged, or otherwise materially damaged.
grains from which the external casings and whole or parts of the germ have been removed in an appropriate manner, using mechanical treatment
all organic and inorganic material other than pearl millet, broken kernels, other grains and filth. Foreign matter includes loose Pearl millet seed coats.
grains that are not properly developed
any seed which if present in quantities above permissible limit may have damaging or dangerous effect on health, organoleptic properties or technological performance such as Jimson weed — Datura (D. fastuosa Linn and D. stramonium Linn.) corn cokle (Agrostemma githago L., Machai Lallium remulenum Linn.) Akra (Vicia species), Argemone mexicana, Khesari and other seeds that are commonly recognized as harmful to health
Sprouted grains are those with any visible evidence of root system beginning to emerge.
the density of a measured volume of grain expressed in kilograms per hectolitre
Sorghum grains shall meet the following general requirements/limits as determined using the relevant standards listed in Clause 2:
Sorghum grains shall be in form of well-filled seeds of uniform colour.
Sorghum grains shall be classified into three grades on the basis of the tolerable limits established in Table 1 which shall be additional to the general requirements set out in this standard.
Shall be sorghum grains which do not fall within the requirements of Grades 1, 2 and 3 of this standard but are not rejected sorghum grains.
Note: For Tanzania and Burundi this requirement shall not apply.
This comprises sorghum grains which have objectionable odour, off flavour, living insects or which do not possess the quality characteristics specified in Table 1. They cannot satisfy the conditions of ungraded sorghum grains and shall be graded as reject sorghum grains and shall be regarded as unfit for human consumption.
