5、te.In the bending fatigue mode,this testmethod evaluates both the adhesion of the coating as well asthe effects that the coating may have on the substrate material.These methods are limited to testing in air at ambient tempera-ture.These test methods are not intended for application infatigue tests
6、of components or devices;however,the testmethod which most closely replicates the actual loadingconfiguration is preferred.1.2 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 equivalents;therefore,each
7、system shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.3 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 standard to establish
