1、Designation: D3823 07 (Reapproved 2012)Standard Practice forDetermining Ticket Numbers for Sewing Threads1This standard is issued under the fixed designation D3823; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last r

2、evision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice establishes standard ticket numbers forsewing thread regardless of fiber content or type of thread.1.2 The val

3、ues stated in inch-pound units are to be regardedas the standard; the values in English units are provided asinformation only and are not exact equivalents.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of

4、 this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

Terminology3.1 For all terminology relating to D13.58, Yarns andFibers, refer to Terminology D4849.3.1.1 The following terms are relevant

6、 to this standard:geige thread, sewing thread, ticket number.3.2 For all other terms are related to textiles, refer toTerminology D123.4. Significance and Use4.1 This system of sewing thread ticket numbers wasdeveloped to overcome the confusion arising from the use bythe thread industry of a multipl

7、e number of undefined andunrelated ticketing systems.4.2 The practice is used by sewing thread manufacturers todetermine the ticket number to be assigned to a sewing thread.The ticket number is an indicator of the amount of raw fiber inthe thread. It is based on greige thread rather than finishedthr

8、ead because finishing processes such as bleaching, dyeing,stretching, mercerizing, or sewing finish application signifi-cantly change the apparent thread size so that it may become aninadequate indicator of raw fiber present. Because of theforegoing it is not practical to verify the ticket number by

Sampling5.1 LotUnless otherwise agreed upon between the pur-chaser and supplier, a lot shall be a discrete manufacturing unitproduced in a given period of time not to exceed a calendarmonth.5.2 Lot SampleSelect the number of specimens as di-rected in ANSI/ASQC Z1.4 usin

If the greigethread of interest has not been produced in at least 6 of the prior12 months, collect at least 100 pairs of data consisting of a texvalue and the corres
