1、Designation: D4030/D4030M 091Standard Specification forGlass Fiber Cord and Sewing Thread1This standard is issued under the fixed designation D4030/D4030M; the number immediately following the designation indicates theyear of original adoption or, in the case of revision, the year of last revision.
2、A number in parentheses indicates the year of lastreapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval.1NOTEThe inch-pound units were put in brackets editorially in September 2010.1. Scope1.1 This specification covers the requirements for continu-o
3、us glass filament sewing thread; and continuous filament cord,untreated and neoprene treated.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 reg
4、arded separately as standard. The values stated ineach system may not be exact equivalents; 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 thesafet
5、y concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

8、extile terms used in thisspecification, refer to Terminology D123.4. Designation of Construction4.1 The yarn designations of fiber glass cords and sewingthreads are specified as directed in Specification D578 exceptthat for the cords either the letter “U” or the letter “N” is addedto the last segmen
9、t of the designation.4.1.1 Cord designations may include a type number 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 lar
10、ger than 2, etc. The second characterof this designation is the letter “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
11、 thread construction includes a type numberthat describes a manufacturers 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 tosho
