"JJF 1255-2010 Film thickness meter calibrating specification" is suitable for various specifications of pointer and digital display Film thickness meter, its scale interval/resolution is 0.1 mm, 0.01 mm, 0.002 mm, 0.001 mm, measurement range is 0 mm to 30 mm. This standard specifies the calibration method of Film thickness meter in detail, including the selection of measuring instrument, calibrating procedure and data processing requirements. The standard cites "JJF 1001-1998 General Measurement Terms and Definitions", "JJF 1059-1999 Measurement Uncertainty Evaluation and Representation", "JJF 1094-2002 Measuring instrument characteristic evaluation" and "GB/T 22520-2008 Film thickness indication table" and other documents. By following this specification, the accuracy and reliability of the Film thickness table in the measurement of film thickness of sheet and plate parts can be ensured, and it provides necessary technical support for various industrial applications.
