within fastener manufacturing plants inNorth America has been focused on development of in-process controls and preventiontechniques which have significantly reduced nonconformances and reduced or eliminatedthe need for final inspection.In selective applications and products,the traditional finalinspection has been replaced by performance testing which assures the completed productfully qualifies for its intended fit.form,and function.It is intended that the purchaser,prior to written agreement,conduct an audit of the manufacturers plant to verify capabilityof compliance with an agreed to control plan to comply with this Standard.In 1996 an IFI task force developed a quality standard for fasteners based on this existingpractice and identified it as IFI-151.IFI subsequently proposed to Subcommittee 18 ofStandards Committee B18 that FI-151 serve as the basis for preparation of an ASMEStandard.Following approval by ASME,this Standard was submitted to the American NationalStandards Institute,which approved it on January 6.1998.with ASMENo reproduction or networking permitled without license from IHSNot for ResaleSTD.ASME B18.1B.7M-ENGL19980759b70Db04773539ASME
