Dieser Teil von ISO 10360 spezifiziert die Annahmeprüfung zur Bestätigung der vom Hersteller festgelegten Leistungsfähigkeit eines für die Messung von kalibrierten Längenmaßen genutzten KMG. Er legt auch die Bestätigungsprüfungen fest, welche es dem Anwender erlauben, die Leistungsfähigkeit des KMG in wiederkehrenden Zeitabständen erneut zu überprüfen. Die in diesem Teil von ISO 10360 angegebenen Annahme- und Bestätigungsprüfungen sind nur auf kartesische KMG mit taktilen Tastsystemen beliebigen Typs bei Einzelpunktantastung anwendbar. Diese Norm ist nicht ausdrücklich auf nicht-kartesische KMG anwendbar, jedoch können die Partner durch gegenseitige Vereinbarung diesen Teil von ISO 10360 auch auf nicht-kartesische KMG anwenden. Diese Norm ist nicht ausdrücklich auf KMG anwendbar, welche optische Antastsysteme verwenden, jedoch können die Partner durch gegenseitige Vereinbarung diese Methoden auch für optische KMG benutzen.
Diese internationale Norm enthält Leistungsanforderungen, welche vom Hersteller oder vom Anwender eines KMG festgelegt werden können, die Art und Weise der Durchführung der Annahme- und Bestätigungsprüfung zum Nachweis der festgelegten Anforderungen, Regeln für die Leistungsüberprüfung, sowie Anwendungen, für welche die Annahme- und Bestätigungsprüfungen verwendet werden können.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 10360-2 was prepared by Technical Committee ISO/TC 213, Dimensional and geometrical product
specifications and verification.
This third edition cancels and replaces the second edition (ISO 10360-2:2001), which has been technically
revised.
ISO 10360 consists of the following parts, under the general title Geometrical product specifications (GPS) —
Acceptance and reverification tests for coordinate measuring machines (CMM):
⎯ Part 1: Vocabulary
⎯ Part 2: CMMs used for measuring linear dimensions
⎯ Part 3: CMMs with the axis of a rotary table as the fourth axis
⎯ Part 4: CMMs used in scanning measuring mode
⎯ Part 5: CMMs using single and multiple stylus contacting probing systems
⎯ Part 6: Estimation of errors in computing Gaussian associated features
⎯ Part 7: CMMs equipped with imaging probing systems

Introduction
This part of ISO 10360 is a geometrical product specification (GPS) standard and is to be regarded as a
general GPS standard (see ISO/TR 14638). It influences link 5 of the chains of standards on size, distance,
radius, angle, form, orientation, location, run-out and datums. For more detailed information of the relation of
this part of ISO 10360 to other standards and the GPS matrix model, see Annex F.
The tests of this part of ISO 10360 have three technical objectives:
1) to test the error of indication of a calibrated test length using a probing system without any ram axis stylus
tip offset;
2) to test the error of indication of a calibrated test length using a probing system with a specified ram axis
stylus tip offset; and
3) to test the repeatability of measuring a calibrated test length.
The benefits of these tests are that the measured result has a direct traceability to the unit length, the metre,
and that it gives information on how the CMM will perform on similar length measurements.
Clause 3 of this part of ISO 10360 contains definitions that supersede similar definitions in ISO 10360-1:2000.
The revised definitions are required to avoid an ambiguity that would otherwise have been introduced with this
issue of ISO 10360-2. Also, definition 3.6 supersedes effectively an identical definition in ISO 10360-1:2000
because the symbols used have been revised and expanded for clarification.

Part 2:
CMMs used for measuring linear dimensions
1 Scope
This part of ISO 10360 specifies the acceptance tests for verifying the performance of a coordinate measuring
machine (CMM) used for measuring linear dimensions as stated by the manufacturer. It also specifies the
reverification tests that enable the user to periodically reverify the performance of the CMM.
The acceptance and reverification tests given in this part of ISO 10360 are applicable only to Cartesian CMMs
using contacting probing systems of any type operating in the discrete-point probing mode.
This part of ISO 10360 does not explicitly apply to:
⎯ non-Cartesian CMMs; however, parties may apply this part of ISO 10360 to non-Cartesian CMMs by
mutual agreement;
⎯ CMMs using optical probing; however, parties may apply this approach to optical CMMs by mutual
agreement.
This part of ISO 10360 specifies performance requirements that can be assigned by the manufacturer or the
user of a 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.

artefacts.
NOTE 2 The MPL may be expressed using any of the methods shown in Figure 12, Figure 13 and Figure 14 of
ISO 10360-1:2000.

5 Environmental and metrological requirements
5.1 Environmental conditions
Limits for permissible environmental conditions, such as temperature conditions, air humidity and vibration at
the site of installation, that influence the measurements shall be specified by:
⎯ the manufacturer, in the case of acceptance tests;
⎯ the user, in the case of reverification tests.
In both cases, the user is free to choose the environmental conditions under which the ISO 10360-2 testing
will be performed within the specified limits (as supplied in the data sheet of the manufacturer; see
ISO 10360-1, Amendment 1).
The user is responsible for providing the environment enclosing the CMM, as specified by the manufacturer in
the data sheet.
If the environment does not meet the specifications, then verification of the maximum permissible errors,
E , E , and maximum permissible limit, R , cannot be required.

(i.e. table) surface and/or on individual point loads (kg/cm ); for point loads, the load at any specific
contact point shall be no greater than twice the load of any other contact point;
⎯ unless otherwise specified by the manufacturer, the load shall be located approximately centrally and
approximately symmetrically at the centre of the CMM table.
The user and manufacturer should arrange for the availability of the load.
The user and the manufacturer should discuss the loading of the CMM table since access to measurement
positions may be impaired by the load.
