Alcance y aplicabilidad

This standard is applicable to the production, trade, processing, quality supervision, and import/export inspection of sheep wool (including superfine wool, fine wool, medium fine wool, improved wool, and native wool). It is mandatory for all manufacturers and traders dealing with sheep wool in China. It does not apply to other animal fibers or man-made fibers.

Requisitos técnicos

The standard classifies homogeneous wool into different models and specifications based on mean fibre diameter ranges, staple length, and allowable percentages of coarse wool, kemp hair, and faulty wool. It specifies strict limits on vegetable matter content and requires separate packaging for colored wool, skirting wool, and head/leg/tail wool. Manufacturers must ensure that the net wool content and yield are accurately calculated and labeled. The standard also defines criteria for identifying tender wool based on staple strength thresholds.

Métodos de ensayo

Testing methods include projection microscopy (GB/T 10685), airflow instruments, and optical fiber diameter analyzers (GB/T 21030) for measuring fibre diameter. Staple length is tested according to GB/T 6976, while staple strength follows GB/T 27629. The standard also details procedures for washing, drying, and calculating wool base, vegetable matter base, and clean wool content using specific chemical extraction and ashing methods.
