ISO 10360-12-2016 pdf download.Geometrical product specifications (GPS) – Acceptance and reverification tests for coordinate measuring systems (CMS)一 Part 12: Articulated arm coordinate measurement machines (CMM).
This part of Iso 10360 specifies the acceptance tests for verifying the performance of an articulated arm CMM by measuring calibrated test lengths as stated by the manufacturer. It also specifies the reverification tests that enable the user to periodically reverify the performance of the articulated arm CMM. It applies to articulated arm CMMs using tactile probes and optionally optical distance sensors (also referred to as laser line scanners or laser line probes). Details on tests for scanner accessories are given in Annex E.
This part of ISO 10360 does not specify how often or when testing is performed, if at all, nor does it specify which party should bear the cost of testing.
This part of ISO 10360 specifies
— performance requirements that can be assigned by the manufacturer or the user of the articulated arm CMM,
— 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.

3 Terms and definitions
For the purposes of this document, the following terms and definitions given in ISO 10360-1 and the following apply.
NOTE The definitions in this section are intended to concisely state the meaning of terms. For metrological characteristics that have numerical values, the complete description of the procedure and derivation of test results in Clause 6 and Annex E are to be followed in determining values.
3.1 articulated arm coordinate measuring machine
system that measures spatial coordinates and comprises
— an open chain affixed-length segments,
— joint assemblies interconnecting the segments and the probing system and attaching them to the stationary environment, and
— a probing system at the free end of the chain
Note 1 to entry: The probing system may comprise a rigid probe or a sensing system such as a scanner.
Note 2 to entry: Rotary joint assemblies connected to the fixed-length segments are equipped with angular encoders. Cartesian coordinates of each measuring point are calculated from the measured angles and segment lengths.
3.2 joint connection between adjacent elements of an articulated arm CMM that allows a single rotational degree of freedom between these elements
Note 1 to entry: There are two types of joints: hinge joints, which cause a hinging movement between adjacent arm segments, and swivel joints, which cause a rotary movement around the axis of the connected arm segment.
Note 2 to entry: Each joint ordinarily includes an angle measuring device (rotary encoder).
3.3 joint assembly assembly of two or more joints between two adjacent elements of an articulated arm CMM.ISO 10360-12 pdf download.
