The measuring faces (2 sides) are ground and micro-lapped to surface roughness of Ra 0.016 while the non-measuring faces (4 sides) are maintained at Ra 0.63. The mirror-finished surface allows the gage block to be easily wringable.

Each gage block is laser marked with a nominal length and serial number with reference to the calibration certificate.

Inspections take place in a ISO-9001 certified laboratory and each block's measurement is recorded on the NIST traceable certificate, not a ISO17025 long form certificate.

Each block is wrapped in a greasproof paper and placed inside a wooden insert holder to prevent corrosion and abrasion.
