ÖNORM EN ISO 10360-5 specifies acceptance and periodic reverification tests of CMM performance with contacting probing systems and is only applicable to CMMs using: any type of contact-probing system; discrete point probing mode; spherical and hemispherical styli. It complements ISO 10360-7 which is the module for CMMs with video probing systems, and ISO 10360-2 which is universal, i.e. not probe type specific. When relevant, this part of ISO 10360 also applies to: multiple-stylus probing systems with fixed multiple-styli attached to a single probe (e.g. "star" stylus); multiple-probing systems such as those with a stylus for each of their probes; systems with articulating probing; stylus and probe changing systems; manual (non-driven) CMMs. This part of ISO 10360 is not applicable to non-contact probing systems, which require different testing procedures. The terms ¿Multi-stylus Size Error¿, etc., should strictly be ¿Combined CMM and Multiple Stylus Probing System Size Error¿, etc., but the wording has been truncated to the minimum which avoids ambiguity, for convenience. However, If it is desired to isolate the probing system performance as far as is practical, the influence of the CMM may be minimised.
