Scope

O’z DSt 645:2010 applies to cotton lint (linters) produced by ginning and other primary processing of cottonseed. The standard covers definitions, classification by quality, general technical requirements (including moisture limits, permissible contamination and foreign matter), sampling and acceptance principles, packaging, marking and storage conditions necessary to ensure suitable quality for textile spinning and industrial uses. It is intended for use by producers, ginneries, laboratories, traders and regulatory bodies involved in the cotton supply chain.

Key topics and requirements

• Definitions and terminology for cotton lint (linters) and associated by‑products.
• Quality classes and acceptance criteria (physical appearance, colour and external condition).
• Maximum permissible levels of impurities and foreign matter (seeds, husk fragments, dust, plant matter).
• Moisture content limits and requirements for sampling and moisture measurement.
• Packing, bale weight ranges, labelling and marking requirements for transport and storage.
• Storage and handling recommendations to avoid contamination and moisture damage.
• References to companion test methods / sampling standards used to verify specified parameters.

Typical use and users

Primary users are cotton ginneries, lint processors, textile mills, exporters and trading companies, national conformity assessment bodies and inspection laboratories. The standard is used when specifying product quality in purchase contracts, for internal quality control at gins and mills, and by regulators responsible for agricultural and industrial product standards. It is also used by certification and testing laboratories that perform acceptance testing and sampling.
