This part of ISO 10360 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 This part of ISO 10360 is not applicable to non-contact probing systems, which require different testing procedures.
