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
12、r shall be electrical grade, free of any free alkalimetal oxides, such as soda or potash, and foreign particles, dirt,and other impurities.6.

Filament Diameter7.1 The nominal filament diameter of fiber glass cords shallbe designated by the letter desig
17、nation “G”. The nominalfilament diameter of fiber glass sewing threads shall bedesignated by the letter designation “B” to “DE”, as applicable.The numerical values associated with letter designations arespecified in Specification D 578. The average filament diam-eter for the yarns in the cord or sew

Yarn Number8.1 Since the yarn number in the designation does notinclude size, the nominal yarn
19、 number for strands includingsize is stated separately for strands listed in Table 1, Table 2,orTable 3. For strands not listed in those tables, the nominal yarnnumber including size shall be agreed upon between thepurchaser and the supplier. The average yarn number for the lotshall be within the in
