2、last revision. A number in parentheses indicates the year of lastreapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval.1 NOTEThe inch-pound units were put in brackets editorially in September 2010.1. Scope1.1 This specification covers the requiremen
3、ts for continuous glass filament sewing thread; and continuous filament cord,untreated and neoprene treated.1.2 This specification is intended to assist ultimate users by designating the types of these products that are typical in theindustry.1.3 The values stated in either SI units or inch-pound un
4、its are to be regarded separately as standard. The values stated in eachsystem may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from thetwo systems may result in nonconformance with the standard.1.4 This standard does not purport to addr
5、ess all of the safety concerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatorylimitations prior to use.2.

Direction of Twist10.1 For glass fiber cords the primary twist shall be“ Z” twist and the final twist shall be “S” twist unless otherwise agreed uponbetween the purch
24、aser and the seller.supplier. For glass fiber sewing threads the primary twist shall be “S” twist and the final twistshall be “Z” twist unless otherwise agreed upon between the purchaser and the supplier.11.

The minimum breaking strength of glass fiber sewing thread listed in Table 3 shall conform to the requirements ofTable 3. The minimum break
29、ing strength of other r glass fiber cords or sewing threads shall be agreed upon between the purchaserand the supplier. No individual break shall be less than the specified minimum breaking strength.13. Yarn Diameter13.1 The nominal yarn diameter for some generally available glass fiber cords are li
30、sted in Table 1 or Table 2, and the nominalyarn diameter for some generally available glass fiber sewing threads are listed in Table 3.The nominal yarn diameters are includedfor information only and are not considered a cause for rejection unless otherwise agreed upon, as when specified in an applic
