For the purposes of this document,
the terms and definitions given in ISO/IEC Guide 99 and ISO/IEC 17000 and the
following 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/
Terminology:
3.1 Integrity:
"Freedom from conflict of interest," "Freedom from bias,"
"Freedom from prejudice and favoritism," "Non-prejudice and
non-discrimination," "Impartiality," "Fairness,"
"Open-mindedness," "Justice," "Separation," and
"Balance."
3.2 Complaints:
"A complaint expresses the dissatisfaction of any person or organization
with a laboratory (3.6), particularly concerning the activities or results of
tests or calibrations carried out in that laboratory, and the laboratory is
expected to respond to it."
3.3 Inter-laboratory
Comparison: "The organization, performance,
and evaluation of measurements or tests carried out on the same or similar
materials in two or more laboratories according to predefined conditions."
3.4 Intra-laboratory
Comparison: "The organization, performance, and
evaluation of measurements or tests carried out on the same or similar
materials within the same laboratory (3.6) according to predefined
conditions."
3.5 Proficiency
Testing: "The evaluation of participants' performance
against predefined criteria." By way of comparisons between laboratories
(3.3)
3.6 Laboratory:
The body that performs one or more of the following activities:
-
Testing.
-
Calibration.
-
Sampling and
testing or calibration.
3.7 Decision
rule: The rule that determines how to handle the
calculation of measurement uncertainty when stating conformity to a specified
requirement.
3.8
Verification: Providing objective evidence that a
particular item meets a specified requirement.
-
Example 1:
Confirming the claim that a reference material is homogeneous for a specific
quantity and method of measurement of a mass of 10 milligrams.
-
Example 2:
Confirming that the performance characteristics or legal requirements of a
measurement system are met.
-
Example 3:
Confirming that the target measurement uncertainty is achievable.
-
Supplementary
note 1: Measurement uncertainty values should be
considered whenever possible.
-
Supplementary
note 2: An item may be, for example, a measurement process
or procedure. Or a substance, compound, or measurement system.
-
Supplementary
Note 3: The specific requirement may be, for example, that
the manufacturer's specifications have been met.
-
Supplementary
Note 4: In legal metrology, as defined in the International
Dictionary of Legal Metrology Terms, and in conformity assessment more
generally, verification involves the examination, marking, and/or certification
of a measurement system.
Supplementary
Note 5: Verification should not be confused with
calibration. Not every verification constitutes validation (3.9).
Supplementary
Note 6: In chemistry, verifying the identity of the entity
or activity under examination requires a description of the structure or
characteristics of that entity or activity.

3.9
Verification: "Verification (3.8) that specific
requirements are appropriate for the application."
