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 14253-3 was prepared by Technical Committee ISO/TC 213, Dimensional and geometrical product
specifications and verification.
This first edition of ISO 14253-3 cancels and replaces ISO/TS 14253-3:2002, which has been technically
revised.
ISO 14253 consists of the following parts, under the general title Geometrical product specifications (GPS) —
Inspection by measurement of workpieces and measuring equipment:
Part 1: Decision rules for proving conformance or non-conformance with specifications
Part 2: Guidance for the estimation of uncertainty in GPS measurement, in calibration of measuring
equipment and in product verification
Part 3: Guidelines for achieving agreements on measurement uncertainty statements
Part 4: Background on functional limits and specification limits in decision rules [Technical Specification]

SIST EN ISO 14253-3:2011
ISO 14253-3:2011(E)
Introduction
This part of ISO 14253 is a geometrical product specification (GPS) International Standard and is to be
regarded as a global GPS Standard (see ISO/TR 14638). It influences links 4, 5 and 6 of all chains of
standards in the general GPS matrix.
The ISO/GPS Masterplan given in ISO/TR 14638 gives an overview of the ISO/GPS system of which this part
of ISO 14253 is a part. The fundamental rules of ISO/GPS given in ISO 8015 apply to this part of ISO 14253
and the default decision rules given in ISO 14253-1 apply to specifications made in accordance with this part
of ISO 14253, unless otherwise indicated.
For more detailed information on the relation of this International Standard to other standards and the GPS
matrix model, see Annex A.
ISO 14253-1 provides decision rules for proving conformance or non-conformance with specifications of
workpieces and measuring equipment when taking into account the uncertainty of measurement. ISO 14253-2
provides instructions for preparing uncertainty budgets for determining measurement uncertainty as defined in
the Guide to the Expression of Uncertainty in Measurement (GUM). However, the possibility still exists that
disagreement between customer and supplier can occur on the estimated measurement uncertainty.
It is becoming increasingly common for suppliers to have in place a quality system providing satisfactory
assurance to the customer that the latter is receiving a product which conforms to specifications. This avoids
the need for costly duplicate inspections.
For this reason, the most common case of disagreement over a measurement uncertainty statement or an
uncertainty budget involves the customer questioning the supplier's uncertainty budget. The customer may
also question the measured value of a characteristic of a workpiece or of measuring equipment, thus indirectly
questioning the total uncertainty budget (see ISO 14253-1).
In a rarer case of disagreement, the supplier may question the customer's uncertainty budget when the
customer rejects a workpiece or measuring equipment (see ISO 14253-1:1998, 6.2).
In addition to those mentioned, there are other cases of disagreement, as well as other motivations that may
lead to discussion of stated uncertainties.

For the purposes of this document, the terms and definitions given in ISO 14253-1, ISO 14253-2, ISO 14978,
ISO 17450-1, ISO 17450-2, ISO/IEC Guide 98-3 and ISO/IEC Guide 99 apply.
4 Reaching an agreement on a stated expanded uncertainty
4.1 Early agreement on the stated measurement uncertainty
In a case where either the customer's or supplier's measurement uncertainty statement is in question, an
uncertainty budget supporting and documenting the measurement uncertainty statement may be necessary. It
is the responsibility of the party preparing the uncertainty budget to justify the individual components and the
resulting estimated expanded uncertainty of the uncertainty budget.
In an ideal situation, customer and supplier will address the issue of measurement uncertainty at the same
time as they address the product specifications of the workpiece, at the pre-contract stage. Agreement on the
magnitude of the measurement uncertainty or uncertainties and the rules for its application at this early stage
of the business relationship will avoid later disputes over acceptance or rejection of product and the
consequent need to apply the default rules given in ISO 14253-1.
NOTE In most cases, there are several GPS characteristics specified for a workpiece and for each of these
characteristics a measuring task with corresponding measurement uncertainty statement is required.
Two different persons can produce two different uncertainty statements due to differing knowledge,
experience and assumptions. Resolving these differences at the pre-contract stage is likely to be less
contentious and less costly than waiting until an argument develops over the acceptance or rejection of the
product during the manufacture and delivery stage.
4.2 Possibilities for solving disagreements over a stated measurement uncertainty
The most basic way of reaching an agreement is to agree to choose one of the two statements of
measurement uncertainty from either party to the agreement. If this type of settlement is not appropriate,
another solution is to use the more refined procedure given in Clause 5, or to use a third party consultation or
a review or both.
Clause 6 of ISO 14253-1:1998 gives specific rules on dealing with uncertainty of measurement when proving
conformance or non-conformance with a specification:
supplier proving conformance with specifications (ISO 14253-1:1998, 6.2);
customer proving non-conformance with specifications (ISO 14253-1:1998, 6.3).
The magnitude of the measurement uncertainty is of importance, because it decreases the conformance zone
(supplier proving conformance) and the non-conformance zone (customer proving non-conformance).
NOTE 1 Decreasing the non-conformance zone increases the interval where non-conformance cannot be proven.
According to ISO 14253-1, the measurement uncertainty is stated by the party providing the proof of conformance or non-
conformance with a specification, i.e. the party making the measurements. In the following clauses of this part of
ISO 14253, the party stating the measurement uncertainty is designated “party 1”. The other of the two parties is
designated “party 2”. “Party 2” is the party likely to question or disagree with the stated measurement uncertainty.
NOTE 2 When the supplier is proving conformance with specification, the supplier is “party 1” and it is the customer,
“party 2”, who provides the specification. When the customer is proving non-conformance, the customer is “party 1” and is
also considered to have provided the specification, hence it is the supplier who is “party 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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
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.
In other circumstances, particularly when there is an urgent market requirement for such documents, a technical
committee may decide to publish other types of normative document:
an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in an
ISO working group and is accepted for publication if it is approved by more than 50 % of the members of the
parent committee casting a vote;
an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical
committee and is accepted for publication if it is approved by 2/3 of the members of the committee casting a
vote.
An ISO/PAS or ISO/TS is reviewed after three years with a view to deciding whether it should be confirmed for a
further three years, revised to become an International Standard, or withdrawn. In the case of a confirmed ISO/PAS
or ISO/TS, it is reviewed again after six years at which time it has to be either transposed into an International
Standard or withdrawn.
Attention is drawn to the possibility that some of the elements of this part of ISO/TS 14253 may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO/TS 14253-3 was prepared by Technical Committee ISO/TC 213, Dimensional and geometrical product
specifications and verification.
ISO 14253 consists of the following parts, under the general title Geometrical Product Specifications (GPS) —
Inspection by measurement of workpieces and measuring equipment:
Part 1: Decision rules for proving conformance or non-conformance with specifications
Part 2: Guide to the estimation of uncertainty in GPS measurement, in calibration of measuring equipment and
in product verification
Part 3: Guidelines for achieving agreements on measurement uncertainty statements

Introduction
This part of ISO 14253 is a geometrical product specification (GPS) Technical Specification and is to be regarded
as a global GPS Technical Specification (see ISO/TR 14638). It influences links 4, 5 and 6 of all chains of
standards in the general GPS matrix.
For more detailed information of the relation of this Technical Specification to other standards and the GPS matrix
model, see annex A.
ISO 14253-1 provides decision rules for proving conformance or non-conformance with specifications of
workpieces and measuring equipment when taking into account the uncertainty of measurement. ISO/TS 14253-2
provides instructions for preparing uncertainty budgets for determining measurement uncertainty as defined in the
Guide to the Expression of Uncertainty in Measurement (GUM). However, the possibility still exists that
disagreement between customer and supplier can occur on the estimated measurement uncertainty.
It is becoming increasingly common for suppliers to have in place a quality system providing satisfactory assurance
to the customer that the latter is receiving a product which conforms to specifications. This avoids the need for
costly duplicate inspections.
For this reason, the most common case of disagreement over a measurement uncertainty statement or an
uncertainty budget involves the customer questioning the supplier's uncertainty budget. The customer also may
question the measured value of a characteristic of a workpiece or of measuring equipment, thus indirectly
questioning the total uncertainty budget (see ISO 14253-1).
In a rarer case of disagreement, the supplier may question the customer’s uncertainty budget when the customer
rejects a workpiece or measuring equipment (see 6.2 of ISO 14253-1:1998).
In addition to those mentioned, there are other cases of disagreement, as well as other motivations that may lead
to discussion of stated uncertainties.

3 Terms and definitions
For the purposes of this part of ISO 14253, the terms and definitions given in ISO 14253-1, ISO/TS 14253-2,
ISO 14978, ISO/TS 17450-1, ISO/TS 17450-2, VIM and GUM, and the following apply.
3.1
operator
ordered set of operations
3.2
specification operator
ordered set of specification operations
NOTE 1 The specification operator is the result of the full interpretation of the combination of the GPS specification or
specifications indicated in the technical product documentation in accordance with ISO GPS standards.
NOTE 2 A specification operator can be incomplete, in which case it could introduce specification uncertainty.
NOTE 3 A specification operator is intended to define, for example, a specific possible “diameter” in a cylinder (e.g. two-point
diameter, minimum circumscribed circle diameter, maximum inscribed circle diameter, Least Squares circle diameter), and not
the generic concept “diameter”.
NOTE 4 The difference between the specification operator and the functional operator causes correlation uncertainty.
3.3
verification operator
ordered set of verification operations
NOTE 1 The verification operator is the metrological emulation of a specification operator. The verification operator is the
basis for the measurement procedure.
NOTE 2 A verification operator might not be a perfect simulation of the given specification operator. In that case, the
differences between the specification operator and the verification operator will result in uncertainty contributors, which are part
of the measurement uncertainty.
3.4
actual specification operator
specification operator derived from the actual specification given in the actual technical product documentation
NOTE 1 The standard or standards according to which the actual specification operator is to be interpreted are identified
explicitly or implicitly.
NOTE 2 An actual specification operator can be a complete specification operator or an incomplete specification operator.
NOTE 3 An actual specification operator can be either a special specification operator or a default specification operator.
3.5
actual verification operator
ordered set of actual verification operations
NOTE The actual verification operator can be chosen so that it is different from the required perfect verification operator.
The divergence between the perfect verification operator and the chosen actual verification operator is the measurement
uncertainty (sum of the method uncertainty and implementation uncertainty).
3.6
perfect verification operator
verification operator based on a full set of perfect verification operations performed in the prescribed order
NOTE 1 The only measurement uncertainty contributions from a perfect verification operator are from metrological
characteristic deviations in the implementation of the operator.
NOTE 2 The purpose of calibration is generally to evaluate the magnitude of these measurement uncertainty contributors,
originating from the measuring equipment.

3.7
specification uncertainty
uncertainty inherent in an actual specification operator when applied to a real workpiece/feature
NOTE 1 Specification uncertainty is of the same nature as measurement uncertainty and can — if relevant — be part of an
uncertainty budget.
NOTE 2 The specification uncertainty quantifies the ambiguity in the specification operator.
NOTE 3 For the purposes of this part of ISO 14253, specification uncertainty is considered part of the compliance
uncertainty.
NOTE 4 Specification uncertainty is a property related to the actual specification operator.
NOTE 5 The magnitude of the specification uncertainty is also dependent on the expected or actual variation of the
geometrical characteristics (deviations of form and angularity) of workpieces.
3.8
simplified verification operator
verification operator including one or more simplified verification operations or deviations from the prescribed order
of operations, or both
NOTE 1 The simplified verification operations, deviation in the order of operations, or both, cause measurement uncertainty
contributions in addition to those measurement uncertainty contributions from the metrological characteristic deviations in the
implementation of the operator.
NOTE 2 The magnitude of these uncertainty contributions is also dependent on the geometrical characteristics (deviations of
form and angularity) of the actual workpiece.
3.9
measuring task
quantification of a measurand according to its definition
[ISO/TS 14253-2:1999, definition 3.3]
3.10
basic measurement task
measurement task(s) which, alone or together with others of its kind, forms the basis for the evaluation of more
complicated characteristics of a workpiece or measuring equipment
[ISO/TS 14253-2:1999, definition 3.4]
3.11
overall measurement task
complicated measuring task, evaluated on the basis of several, possibly different, basic measurements
[ISO/TS 14253-2:1999, definition 3.5]
3.12
measurement
set of operations having the object of determining a value of a quantity
[VIM:1993, definition 2.1]
NOTE For the purposes of this Technical Specification, the term “measuring process” is used as a synonym for
measurement.
3.13
basic measuring process
basic measurement
measuring process which, alone or together with others of its kind, forms the basis of the evaluation/measurement
of more complex GPS characteristics

3.14
overall measuring process
overall measurement
complex measuring process consisting of several, possibly different, basic measuring processes
3.15
task-related calibration
calibration of only the metrological characteristics which influence the measurement uncertainty for the intended
use
NOTE 1 A task-related calibration will normally include only the calibration of those metrological characteristics having a
major influence on the measurement uncertainty for the intended use.
NOTE 2 Task related-calibrations can be performed using other, more economical procedures than those employed in global
calibration; a task-related calibration can be designed to deliver information (values and conditions) optimized for use in the
specific uncertainty budget.
NOTE 3 This definition of task-related calibration has been formulated differently from the definition of the same term given in
ISO 12179, intentionally and without changing the meaning. The difference reflects a development in the GPS field.
[ISO 14978:—, definition 3.11]
4 Reaching an agreement on a stated expanded uncertainty
4.1 Early agreement on the stated measurement uncertainty
In a case where either the customer’s or supplier's measurement uncertainty statement is in question, an
uncertainty budget supporting and documenting the measurement uncertainty statement may be necessary. It is
the responsibility of the party preparing the uncertainty budget to justify the individual components and the resulting
estimated expanded uncertainty of the uncertainty budget.
In an ideal situation, customer and supplier will address the issue of measurement uncertainty at the same time as
they address the product specifications of the workpiece, at the pre-contract stage. Agreement on the magnitude of
the measurement uncertainty or uncertainties and the rules for its application at this early stage of the business
relationship will avoid later disputes over acceptance or rejection of product and the consequent need to apply the
default rules given in ISO 14253-1.
NOTE In most cases, there are several GPS characteristics specified for a workpiece and for each of these characteristics
a measuring task with corresponding measurement uncertainty statement is required.
Two different persons can produce two different uncertainty statements due to differing knowledge, experience and
assumptions. Resolving these differences at the pre-contract stage is likely to be less contentious and less costly
than waiting until an argument develops over the acceptance or rejection of the product during the manufacture
and delivery stage.
4.2 Possibilities for solving disagreements over a stated measurement uncertainty
The most basic way of reaching an agreement is to agree to choose one or the other of the two statements of
measurement uncertainty from either party to the agreement. If this type of settlement is not appropriate, another
solution is to use the more refined procedure given in clause 5, or to use a third party consultation, review or both
these.
Clause 6 of ISO 14253-1:1998 gives specific rules on dealing with uncertainty of measurement when proving
conformance or non-conformance with a specification:
supplier proving conformance with specifications (6.2 of ISO 14253-1:1998);
customer proving non-conformance with specifications (6.3 of ISO 14253-1:1998).

ISO/DIS 14253-3:2002(E)
The magnitude of the measurement uncertainty is of importance, because it decreases (supplier proving
conformance) and increases (customer proving non-conformance) the specification.
According to ISO 14253-1, the measurement uncertainty is stated by the party providing the proof of conformance
or non-conformance with a specification, i.e. the party making the measurements. In the following clauses of this
part of ISO 14253, the party stating the measurement uncertainty is designated “party 1”. The other of the two
parties is designated “party 2”. “Party 2” is the party likely to question or disagree with the stated measurement
uncertainty.
NOTE When the supplier is proving conformance with specification, the supplier is “party 1” and it is the customer,
“party 2”, who provides the specification. When the customer is proving non-conformance, the customer is “party 1” and is also
considered to have provided the specification, hence it is the supplier who is “party 2”.
A number of scenarios can be demonstrated for cases where a stated measurement uncertainty from “party 1” may
be questioned by “party 2”. Figure 1 illustrates the most common scenarios, as follows.
a) A measurement uncertainty is stated by “party 1” (box a).
b) “Party 2” has two
