F型车钩样板校准方法的探讨

摘要

After Type F (including Type FR) couplers are introduced to China from the United States,since the value traceability method for coupler gauge calibration differs greatly from that adopted in China,it is thus a crucial issue to trace and calibrate Type F coupler gauges. The article analyses the features of Type F coupler gauges , dis⁃cusses the value traceability method and the calibration test method proper for Type F coupler gauges in China,with examples given for illustration.%在引进美国的F型（含FR型）车钩后，由于该车钩样板校准的量值溯源方法与我国采用的方法有较大的区别，为此如何对F型车钩样板进行溯源和校准成为十分关键的问题。分析F型车钩样板具有的特点，探讨我国适用的F型车钩样板量值溯源的方式和校准方法，并举例进行说明。
