Geometrical product specifications (GPS) - Acceptance and reverification tests for coordinate measuring systems (CMS) - Part 10: Laser trackers (ISO 10360-10:2021)

This document specifies the acceptance tests for verifying the performance of a laser tracker by
measuring calibrated test lengths, according to the specifications of the manufacturer. It also specifies
the reverification tests that enable the user to periodically reverify the performance of the laser tracker.
The acceptance and reverification tests given in this document are applicable to laser trackers utilizing
a retroreflector, or a retroreflector in combination with a stylus or optical distance sensor, as a probing
system. Laser trackers that use interferometric measurement (IFM), absolute distance measurement
(ADM) or both can be verified using this document. This document can also be used to specify and
verify the relevant performance tests of other spherical coordinate measurement systems that use
cooperative targets, such as “laser radar” systems.
NOTE Systems which do not track the target, such as laser radar systems, will not be tested for probing
performance.
This document does not explicitly apply to measuring systems that do not use a spherical coordinate
system. However, interested parties can apply this document to such systems by mutual agreement.
This document specifies:
— performance requirements that can be assigned by the manufacturer or the user of the laser tracker;
— the manner of execution of the acceptance and reverification tests to demonstrate the stated
requirements;
— rules for proving comformity;
— applications for which the acceptance and reverification tests can be used.

Introduction

This document is a geometrical product specification (GPS) standard and is to be regarded as a general

GPS standard (see ISO 14638). It influences chain link F of the chain of standards on size, distance,

form, orientation, location and run-out.

The ISO/GPS matrix model given in ISO 14638 gives an overview of the ISO/GPS system of which this

document is a part. The fundamental rules of ISO/GPS given in ISO 8015 apply to this document and

the default decision rules given in ISO 14253-1 apply to specifications made in accordance with this

document, unless otherwise indicated.

More detailed information on the relation of this document to other standards and the GPS matrix

model can be found in Annex H.

The objective of this document is to provide a well-defined testing procedure for:

a) laser tracker manufacturers to specify performance by maximum permissible errors (MPEs); and

b) to allow testing of these specifications using calibrated and traceable test lengths, test spheres and

flats.

The benefits of these tests are that the measured result has a direct traceability to the unit of length,

the metre, and that it gives information on how the laser tracker will perform on similar length

measurements.

This document is distinct from ISO 10360-2, which is for coordinate measuring machines (CMMs)

equipped with contact probing systems, in that the orientation of the calibrated test lengths reflects

the different instrument geometry and error sources within the instrument.

— the manner of execution of the acceptance and reverification tests to demonstrate the stated

requirements;
— rules for proving comformity;
— applications for which the acceptance and reverification tests can be used.

ISO and IEC maintain terminological databases for use in standardization at the following addresses:

— ISO Online browsing platform: available at https:// www .iso .org/ obp
— IEC Electropedia: available at http:// www .electropedia .org/
3.1
laser tracker

coordinate measuring system in which a cooperative target is followed with a laser beam and its

location determined in terms of a distance (range) and two angles

Note 1 to entry: The two angles are referred to as azimuth, θ, (rotation about a vertical axis – the standing axis of

the laser tracker) and either elevation, φ, (angle above a horizontal plane – perpendicular to the standing axis) or

zenith (angle from the standing axis).

Note 2 to entry: Care should be used with the symbols associated with spherical coordinate systems, as different

conventions exist. For example, the description of a spherical coordinate system in ISO 80000-2 uses the symbols

differently and uses the zenith angle (away from vertical) rather than elevation.

Note 3 to entry: See Figure 1
Key

3.2
interferometric measurement mode
IFM mode

measurement method that uses a laser displacement interferometer integrated in a laser tracker (3.1)

to determine distance (range) to a target

Note 1 to entry: Displacement interferometers can only determine differences in distance, and therefore require

a reference distance (e.g. home position).

3.3
absolute distance measurement mode
ADM mode

measurement method that uses time of flight instrumentation integrated in a laser tracker (3.1) to

determine the distance (range) to a target

Note 1 to entry: Time of flight instrumentation may include a variety of modulation methods to calculate the

distance to the target.
3.4
retroreflector

passive device designed to reflect light back parallel to the incident direction over a range of incident

angles

Note 1 to entry: Typical retroreflectors are the cat’s-eye, the cube corner and spheres of special material.

Note 2 to entry: Retroreflectors are cooperative targets.

Note 3 to entry: For certain systems, for example laser radar, the retroreflector will possibly be a cooperative

target such as a polished sphere.
3.5
spherically mounted retroreflector
SMR
retroreflector (3.4) that is mounted in a spherical housing

Note 1 to entry: In the case of an open-air cube corner, the vertex is typically adjusted to be coincident with the

sphere centre.

Note 2 to entry: The tests in this document are typically executed with a spherically mounted retroreflector.

Note 3 to entry: See Figure 2.
3.6
stylus and retroreflector combination
SRC

probing system that determines the measurement point utilizing a probe stylus to contact the

workpiece, a retroreflector (3.4) to determine the base location of the probe, and other means to find

the stylus orientation unit vector

Note 1 to entry: The datum for the stylus tip offset (l) is the centre of the retroreflector.

Note 2 to entry: See Figure 2.

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.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).

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. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/patents).

Introduction

This document is a geometrical product specification (GPS) standard and is to be regarded as a general

GPS standard (see ISO 14638). It influences link F of the chains of standards on size, distance, form,

orientation, location, and run-out.

The ISO/GPS matrix model given in ISO 14638 gives an overview of the ISO/GPS system of which this

document is a part. The fundamental rules of ISO/GPS given in ISO 8015 apply to this document and

the default decision rules given in ISO 14253-1 apply to specifications made in accordance with this

document, unless otherwise indicated.

More detailed information on the relation of this document to other standards and the GPS matrix

model can be found in Annex H.

The objective of this document is to provide a well-defined testing procedure for:

a) laser tracker manufacturers to specify performance by maximum permissible errors (MPEs); and

b) to allow testing of these specifications using calibrated and traceable test lengths, test spheres,

and flats.

The benefits of these tests are that the measured result has a direct traceability to the unit of length,

the metre, and that it gives information on how the laser tracker will perform on similar length

measurements.

This document is distinct from ISO 10360-2, which is for coordinate measuring machines (CMMs)

equipped with contact probing systems, in that the orientation of the test lengths reflect the different

instrument geometry and error sources within the instrument.

DRAFT INTERNATIONAL STANDARD ISO/DIS 10360-10:2019(E)
Geometrical product specifications (GPS) — Acceptance
and reverification tests for coordinate measuring
systems (CMS) —
Part 10:
Laser trackers for measuring point-to-point distances
1 Scope

This document specifies the acceptance tests for verifying the performance of a laser tracker by

measuring calibrated test lengths, according to the specifications of the manufacturer. It also specifies

the reverification tests that enable the user to periodically reverify the performance of the laser tracker.

The acceptance and reverification tests given in this document are applicable only to laser trackers

utilizing a retro-reflector as a probing system. Laser trackers that use interferometry (IFM), absolute

distance meter (ADM) measurement, or both can be verified using this document. This standard

can also be used to specify and verify the relevant performance tests of other spherical coordinate

measurement systems that use cooperative targets, such as “laser radar” systems.

NOTE Systems, such as laser radar systems, which do not track the target, will not be tested for probing

performance.

This document does not explicitly apply to measuring systems that do not use a spherical coordinate

system (i.e. two orthogonal rotary axes having a common intersection point with a third linear axis

in the radial direction) however, the parties may apply this part of 10360 to such systems by mutual

agreement.
This document specifies:

— performance requirements that can be assigned by the manufacturer or the user of the laser tracker,

— 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 apply.

ISO and IEC maintain terminological databases for use in standardization at the following addresses:

— ISO Online browsing platform: available at https: //www .iso .org/obp
— IEC Electropedia: available at http: //www .electropedia .org/
3.1
laser tracker

coordinate measuring system in which a cooperative target is followed with a laser beam and its

location determined in terms of a distance (range) and two angles

Note 1 to entry: The two angles are referred to as azimuth, θ (rotation about a vertical axis – the standing axis of

the laser tracker) and elevation, φ (angle above a horizontal plane – perpendicular to the standing axis).

3.2
interferometric measurement mode
IFM mode

measurement method that uses a laser displacement interferometer integrated in a laser tracker (3.1)

to determine distance (range) to a target

Note 1 to entry: Displacement interferometers can only determine differences in distance, and therefore require

a reference distance (e.g. home position).
3.3
absolute distance measurement mode
ADM mode

measurement method that uses time of flight instrumentation integrated in a laser tracker (3.1) to

determine the distance (range) to a target

Note 1 to entry: Time of flight instrumentation may include a variety of modulation methods to calculate the

distance to the target.
3.4
retroreflector

passive device designed to reflect light back parallel to the incident direction over a range of

incident angles

Note 1 to entry: Typical retroreflectors are the cat’s-eye, the cube corner, and spheres of special material.

Note 2 to entry: Retroreflectors are cooperative targets.

Note 3 to entry: For certain systems, e.g. laser radar, the retroreflector might be a cooperative target such as a

polished sphere.
3.5
spherically mounted retroreflector
SMR
retroreflector (3.4) that is mounted in a spherical housing

Note 1 to entry: In the case of an open-air cube corner, the vertex is typically adjusted to be coincident with the

sphere centre.

Note 2 to entry: The tests in this standard are typically executed with a spherically mounted retroreflector.

Note 3 to entry: See Figure 1.

Note 1 to entry: E and E (used frequently in this document) correspond to the common case of no

Av g : 0 : LT B i : 0 : LT

stylus tip offset, as the retroreflector optical centre is coincident with the physical centre of the probing system

for spherically mounted retroreflectors.
3.10
normal CTE material
−6 0 −6 0

material with a coefficient of thermal expansion (CTE) between 8 × 10 / C and 13 × 10 / C

[SOURCE: ISO 10360-2:2009]
