摘　　要：本文介绍了漆膜圆锥弯曲试验仪的工作原理及应用,并基于其工作原理、相关检测标准等,讨论了该设备的计量校准方法,包含细端直径误差、粗端直径误差、锥体长度误差3个主要校准项目;提出了参考的计量技术指标,细端直径误差、粗端直径误差不超过±0.1mm,锥体长度误差不超过±3mm,并对测得值的不确定度进行评定。该校准方法可为漆膜圆锥弯曲试验仪的计量校准提供参考,并保证其量值的准确性和溯源性。This paper introduces the work ing principle and application of the coating bend tester of conical man-drel.Based on the working principle and related testing standards,a calibration method is discussed for the coating bend tester of conical mandrel,including three main calibration items:the small diameter error,the large diameter error and the length error.The reference technical indices are put forward,the small diameter and large diameter er-ror should be under±0.1mm,the length error should be under±3mm,and the uncertainty of the measured val-ues are evaluated.This calibration method can be used as a reference for the measurement and calibration of the coating bend tester of conical mandrel to ensure the accuracy and traceability for the measurement.
