1、Designation: D 4030 04Standard Specification forGlass Fiber Cord and Sewing Thread1This standard is issued under the fixed designation D 4030; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in p

2、arentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers the requirements for continu-ous glass filament sewing thread; and continuous filament cord,untreated and neoprene trea

3、ted.1.2 This specification is intended to assist ultimate users bydesignating the types of these products that are typical in theindustry.1.3 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equivalent

4、s; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in nonconformancewith the standard.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this

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

8、esignation of Construction4.1 The yarn designations of fiber glass cords and sewingthreads are specified as directed in Specification D 578 exceptthat for the cords either the letter “U” or the letter “N” is addedto the last segment of the designation.4.1.1 Cord designations may include a type numbe

9、r thatdescribes the relative diameter of the cords and treatment. Thefirst character of this designation is a numeral from 1 to 10 thatindicates the relative diameter of the cord to other cords, that is,2 is larger than 1, 3 is larger than 2, etc. The second characterof this designation is the lette

10、r “U” or the letter “N”. The “U”indicates that the cord is untreated, and the “N” indicates thatthe cord is neoprene treated. The type number for cord isincluded in Tables 1 and 2 to show its relationship todesignation.4.1.2 Sewing thread construction includes a type numberthat describes a manufactu

11、rers code and the size. The secondcharacter is a numeral and indicates the relative diameter of thesewing threads, that is, 4 is larger than 2, 6 is larger than 4, etc.This type number for sewing thread is included in Table 3 toshow its relationship to designation.REQUIREMENTS5. Material5.1 The fibe
