ISO 11051:1994 — Durum wheat (Triticum durum Desf.) — Specification. This international standard lays down minimum specifications for durum wheat intended for human consumption and international trade, and includes methods and informative annexes related to impurities, grain vitreousness, typical insect pests and harmful or toxic seeds.

Abstract

Lays down minimum specifications for durum wheat (Triticum durum Desf.) intended for human consumption and forming the subject of international trade. Also gives methods for the determination of the level of impurities, the proportion of non-wholly-vitreous grains, a list of typical insect pests of stored cereals and an informative list of harmful and toxic seeds.

Scope

The standard specifies minimum quality criteria and associated test methods for durum wheat traded internationally, including procedures for assessing levels of foreign matter and impurities, determining the proportion of non-wholly-vitreous (broken or chalky) grains, and providing informative lists of stored‑grain insect pests and harmful or toxic seeds. It is intended to support uniform quality assessment in commerce and trade.

Key topics and requirements

• Minimum specification parameters for durum wheat intended for human consumption (grading and quality limits).
• Method(s) for determination of level of impurities (informative/normative guidance in annexes).
• Procedure for determining the proportion of non‑wholly‑vitreous grains (assessment of grain vitreousness).
• Informative lists: typical insect pests of stored cereals (Annex C) and harmful/toxic seeds (Annex D).
• Guidance to support international trade, inspection and quality control routines for durum wheat consignments.

Typical use and users

Used by grain traders, millers, food processors, quality control laboratories, inspection and quarantine authorities, commodity specifiers and purchasing departments involved in international grain trade, and by national standards bodies referencing cereal quality criteria.
