ISO 10360-10:2016 specifies the acceptance tests for verifying the performance of a laser tracker by measuring calibrated test lengths, test spheres and flats according to the specifications of the manufacturer. It also specifies the reverification tests that enable the user to periodically reverify the performance of the laser tracker. The acceptance and reverification tests given in this part of ISO 10360 are applicable only to laser trackers utilizing a retro-reflector as a probing system. Laser trackers that use interferometry (IFM), absolute distance meter (ADM) measurement, or both can be verified using this part of ISO 10360. This part of ISO 10360 can also be used to specify and verify the relevant performance tests of other spherical coordinate measurement systems that use cooperative targets, such as "laser radar" systems.NOTE Systems, such as laser radar systems, which do not track the target, will not be tested for probing performance.ISO 10360-10:2016 does not explicitly apply to measuring systems that do not use a spherical coordinate system (i.e. two orthogonal rotary axes having a common intersection point with a third linear axis in the radial direction). However, the parties can apply this part of ISO 10360 to such systems by mutual agreement.ISO 10360-10:2016 specifies- performance requirements that can be assigned by the manufacturer or the user of the laser tracker,- the manner of execution of the acceptance and reverification tests to demonstrate the stated requirements,- rules for proving conformance, and- applications for which the acceptance and reverification tests can be used.
