JJF 1488-2014 "Specification for calibrating rubber and Plastic film thickness gauges" applies to the calibrating of pointer and digital rubber thickness gauges (Measurement range 0~ 30 mm) and pointer and digital Plastic film thickness gauges (Measurement range 0~ 1 mm). This specification refers to GB/T 6672-2001 "Plastic film and sheet thickness determination, mechanical measurement method", GB/T 22520-2008 "Thickness indicator table" and HG/T 2041-2009 "Technical conditions for rubber Thickness Gauge" and other related standards. Thickness gauges are mounted on specific brackets to measure the thickness of rubber or Plastic films by the linear displacement of the probe and the anvil. Although the measurement force and Measurement range are different, their basic structure and function are similar. This specification ensures the accuracy and Reliability of thickness gauges during the calibration process.
