ISO 10360-8:2013 specifies the acceptance tests for verifying the performance of a CMM (coordinate measuring machine) when measuring lengths as stated by the manufacturer. It also specifies the reverification tests that enable the user to periodically reverify the performance of the CMM. The acceptance and reverification tests are applicable only to Cartesian CMMs with optical distance sensors. While it does not explicitly apply to non-Cartesian CMMs, the parties may apply ISO 10360-8:2013 to non-Cartesian CMMs by mutual agreement.

It is not intended to be applicable to CMMs whose measuring volume is significantly smaller than the size of the test sphere. However, the principle, artefacts and procedure of the test described are useful for the acceptance and reverification tests of those CMMs - either as it is or with modifying the parameters such as the size of the test artefacts and the number of measurements.

ISO 10360-8:2013 specifies performance requirements that can be assigned by the manufacturer or the user of the CMM, the manner of execution of the acceptance and reverification tests to demonstrate the stated requirements, rules for verifying conformance, and applications for which the acceptance and reverification tests can be used.
