1、Designation:D4393/D4393M 10Standard Test Method forStrap Peel Adhesion of Reinforcing Cords or Fabrics toRubber Compounds1This standard is issued under the fixed designation D4393/D4393M;the number immediately following the designation indicates theyear of original adoption or,in the case of revisio
2、n,the year of 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.Scope1.1 This test method covers the determination of peeladhesion of reinforcing fabrics that are bonded to rubbercom
3、pounds.It is applicable to either woven or parallel cordtextile structures from both natural and manmade fibers and toparallel steel cord structures.1.2 This test method is primarily used to evaluate tire cordsand tire cord fabrics,including steel tire cords,using a suitabletire cord adhesive and a
4、suitable rubber compound.This testmethod may be used to evaluate tire cord adhesives(fabricdip),metallic(usually brass)coatings on steel cord,and theprocess of adhesive reaction on the cord using one consistentform of tire cord or fabric and one consistent rubber com-pound.This test method may be us
5、ed to evaluate cords andfabrics in industrial hose and belting products and other cord orfabric reinforced rubber products.1.3 Variables that may contribute to differences in results ofthis test method include adhesive type,adhesive applicationprocedure,adhesive cure,fiber type,construction of cords
6、 orreinforcing fabrics,rubber type,rubber cure,rubber thickness,and cord spacing.21.3.1 The deleterious effect of ozone in combination withatmospheric moisture on the ability of adhesives to bond withrubber requires assiduous protection of cords prior to rubberembedment.31.4 The values stated in eit
7、her SI units or inch-pound unitsare to be regarded 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 non-conformancewith the standard.1.5 This standard d
