This part of ISO 10360 specifies acceptance and periodic reverification tests of the performance of CMMs having multiple-stylus probing systems, including 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, and systems with articulating probing.

The acceptance test and reverification test specified in this part of ISO 10360 are applicable only to the following:

• CMMs using any type of contact-probing system;
• stylus system configurations able to be prequalified (i.e. where the repeatability of the system operation is sufficient so that a stylus qualification is not required for each use);
• spherical, hemispherical and disk-shaped styli.

These tests are not applicable to non-contact probing systems, which require special testing procedures outside the scope of this part of ISO 10360.
