(Specification)Standard Specification for Labeled Length per Holder of Sewing Thread
Standard Specification for Labeled Length per Holder of Sewing Thread
ABSTRACT
This specification covers the requirements for the labeled lengths per holder of sewing threads of all materials. The test specimen is a thread holder whether a cone, tube, spool, ready-made bobbin, or any other holders. The observed length for all holders such as home sewing spools, ready-made bobbins, or all other holders which depends on the sampling size shall equal or exceed a certain percentage of the minimum allowable labeled length.
SCOPE
1.1 This specification covers requirements for the labeled lengths of sewing threads of all materials.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
