Product Code:SAE J1095
Title:Fatigue Test Procedures: Hubs and Wheels for Demountable Rims
Issuing Committee:Truck And Bus Wheel Committee
Scope:This SAE Recommended Practice provides uniform laboratory procedures for fatigue testing of spoke wheels and hubs intended for normal highway use on trucks, buses, truck trailers, and multipurpose passenger vehicles. The hubs included have bolt circle diameters from 165.1 to 335.0 mm (6.50 to 13.19 in). It is up to each hub and/or spoke wheel developer to determine what test method, accelerated load factor and cycle life requirements are applicable to obtain satisfactory service life in a given application. When deviations from the procedures recommended herein are made, it is the responsibility of the hub and/or spoke wheel developer to modify other parameters to obtain satisfactory service life.【英文标准名称】:Copperandcopperalloys-Determinationofimpuritiesinpurecopper-ETAASmethodEnglishversionofDINEN14935:2006-09
