Annex A (informative) Ticket numbers
Annex B (normative) Determination of variation in length
after immersion in boiling water

Defines requirements for industrial sewing thread made either wholly or partly from synthetic fibres. Requirements are defined for industrial sewing threads based upon breaking force in relation to thread size. Also, defines colour fastness and boiling water shrinkage requirements for threads used in the clothing trade.
