Gage Block Calibration

The Gage (gauge) block is the most fundamental and precise length measurement instrument used in today’s metrology laboratories.  In fact, gage blocks are so accurate that they are most often used to calibrate or master other laboratory dimensional measuring equipment such as micrometers, calipers, height gauges and even super-micrometers. What makes gage blocks so essential to a metrology lab and the technicians who use them is their superb length accuracy.  ANSI/ASME grade-00 gage block accuracy can be as small as 2 micro-inches or 0.05 microns – or about the width of 1/1000 of a human hair! These amazingly small tolerances are achieved through extremely tight control of flatness, parallelism and surface finish parameters during the gage block manufacturing process. Unfortunately, gage block accuracy will diminish over time due to wear from frequent use and damage can occur suddenly with accidental drops. To ensure accuracy is maintained, gage blocks should be calibrated on a routine basis by a creditable ISO 17025 accredited calibration service provider. Gage block calibration intervals are best determined by examining how critical the specific measurement is to your processes and how frequently the gage blocks are used.
