Summary
-
Calibration blocks are available as a set or individually, allowing users to select the most appropriate thickness for their application. Elcometer NDT calibration standards are manufactured from 4340 steel to a tolerance of ±1% of the nominal thickness and are supplied complete with calibration certificates.
Selecting the right calibration block
Selecting the correct calibration block for your application is essential to ensure accurate evaluation. The form, shape and material of the calibration block should be appropriate for the material being inspected. Any artificially induced flaw should closely resemble that of the actual flaw being tested for.

Calibration Blocks
Elcometer NDT offer a comprehensive range of Calibration Blocks to suit a wide range of applications and standards.
Summary
Calibration Blocks
Calibration blocks are available as a set or individually, allowing users to select the most appropriate thickness for their application. Elcometer NDT calibration standards are manufactured from 4340 steel to a tolerance of ±1% of the nominal thickness and are supplied complete with calibration certificates.
Selecting the right calibration block
Selecting the correct calibration block for your application is essential to ensure accurate evaluation. The form, shape and material of the calibration block should be appropriate for the material being inspected. Any artificially induced flaw should closely resemble that of the actual flaw being tested for.
