What is ISO 10360? And why is it so important?
coordinate measuring machine
Essentially, this is the international standard of measurement verification that specifies the acceptance tests for verifying the performance of a coordinate measuring machine (CMM) used for measuring linear dimensions as stated by the manufacturer.
It also specifies the re-verification tests that enable the user to periodically re-verify the performance of the CMM. These tests are vital in ensuring your CMM is and stays precise and accurate.
Even though this has been the accepted standard since 1994 internationally, not all coordinate measuring machine manufacturers abide by this certification. There are other standards we mention below that are sometimes used. They are not only less rigorous than the ISO 10360 standards, but they make it impossible to compare one CMM to the next because it is not the standard.

Wenzel America is an accredited 17025 calibration provider, which means we provide 10360 calibrations on all CMMs we sell. As a verified certifier, we can, and do perform these tests for our customers and ourselves.
Is there more than one ISO 10360 test?
Since 1994, ISO 10360-2 specifies three uncertainties: volumetric length measuring uncertainty (MPEE); volumetric probing uncertainty (MPEP); and volumetric scanning error (MPETHP). (MPE is the acronym for Maximum Permissible Error.) Each of these is tested against the standard.

A set of five calibrated gage blocks is used to verify a coordinate measuring machine’s MPEE. Measurements are taken in seven different locations (position and direction) within the CMM’s measuring volume for the test. For each of the seven locations, the length of each of the five gage blocks is measured three times for a total of 105 measurements. All 105 measurements must be within the stated tolerance specified by the manufacturer.
What does this mean for you?
By using a 10360 calibration for your company, it allows you to compare CMM performance between all the machines at your company, as well as, new machines you may desire to purchase. This world standard is more demanding than VDI/VDE 2617, ASME B89.
