1 OBJECTIVE
This document aims to present the definitions of terms used in Cgcre documents related to the activity of
accreditation of laboratories, reference material producers and proficiency testing providers.
2 APPLICATION FIELD
This document applies to Dicla and to the following conformity assessment bodies, accredited or
applying for accreditation: laboratories, proficiency testing providers and reference material producers.
This document also applies to assessors and experts working in the accreditation processes of these
conformity assessment bodies and members of the advisory Technical Committees of Cgcre.
3 RESPONSIBILITY
Dicla is responsible for revising this document.
4 REVISION BACKGROUND AND IMPLEMENTATION DEADLINE
4.1 The definition of the term “subcontracting of laboratories” has been changed and the terms "working
as an agent” and “outsourcing” have been deleted. These changes have been made with the purpose of
eliminating mistaken interpretations about the requirements established in the standards NIE-Cgcre-009
and NIT-Dicla-031.
4.2 The definition of the term “updating the scope” has been changed, so as to clarify the cases in which
the updating can be made. A clarification was made about the impossibility of updating scopes to include
tests in products, properties or analytes.
4.3 Examples for the term “accreditation extension” have been included so as to clarify the cases in
which it is necessary to apply for the accreditation extension.
4.4 Terms whose definitions are mentioned in other documents have been included.
4.5 Small changes have been made so as to improve the definitions of a few terms.
4.6 The definitions from VIM have been updated.
4.7 The most significant changes are marked in yellow.
4.8 This document comes into force on its publication date.

a specific document of Cgcre are mentioned in this document making reference to the document which
mentions its definition.
8 DEFINITIONS
8.1 Warning
Action to notify the CAB about the non compliance with the standard requirements of the accreditation.
Note:
The character of the warning is eminently educative, not configuring a sanction.
8.2 Dicla´s clerical staff
Dicla’s professional responsible for reviewing the application, selecting assessment teams, requesting
costs billing and other clerical activities.
Note:
The financial and contractual matters are managed and operated by the Accreditation Support Section Secre/Cgcre.

Page 4/12
8.3 Fortified Sample, Spike Matrix
See NIT-Dicla-057.
8.4 Sampling (ISO/IEC 17025)
Defined procedure whereby a part of a substance, material or product is taken to provide for testing or
calibration of a representative sample of the whole. Sampling may also be required by the appropriate
specification for which the substance, material or product is to be tested or calibrated. In certain cases
(e.g. forensic analysis), the sample may not be representative but is determined by availability.
Note: See also NIT-Dicla-057.
8.5 Appeal (ISO/IEC 17011)
Request by a CAB for reconsideration of any adverse decision made by the accreditation body related to
the desired accreditation status.
Note: Adverse decisions include the refusal to accept an accreditation application, the interruption of the
assessment process, the request of corrective actions, the changes in the accredited scope, the
decisions to refuse, suspend or cancel the accreditation and any other action that prevents
obtaining the accreditation.
8.6 Activity Areas:
Area including the economic activities in which testing objects are obtained or produced.
Note:
The activity areas are established in NIT-Dicla-016.
8.7 Filing of the Accreditation Process
Action to definitively terminate an accreditation application, at any time before it is granted, at the request
of CAB or by virtue of Cgcre decision.
8.8 Scope Update
8.8.1 For the case of testing and calibration laboratories, as well as for medical testing laboratories, the
update scope is a slight modification to the Scope of Accreditation which does not imply the inclusion of:
a)
a new service of calibration, testing or examination;
b)
new parameters, properties or analytes in calibration or testing services already accredited;
c)
a new product for a testing already accredited;
d)
a new material for an examination already accredited
e)
a new method or technique of examination, calibration, testing or preparation of the item to be
examined, calibrated or tested, for an examination, testing or calibration already accredited.
Note 1: Updating the scope shall not require the detailed review of the method, as it shall remain
essentially the same. More complex changes in the scope require an application of the accreditation
extension.
Note 2: Examples of situations that can lead to updating the scope are:
a)
changing the version of the standard and/or procedure without changing the respective method or
technique mentioned in the standard or procedure;
b)
inclusion of the standard for a testing already accredited that uses method and procedure identical
to the testing already accredited.
c)
for a calibration laboratory: small modifications to the calibration and measurement capability
derived from the reduction of the contribution to the uncertainty from the calibration of standards or
equipment used in calibration;
d)
small changes in the measuring range or in the level of quantification that do not come from the
introduction of a new measurement method or technique and preparation of the testing or
calibration item.
DOQ-CGCRE-020 – Revision 06 – Apr/2013
Page 5/12
8.8.2 For the case of proficiency testing providers, the updating of scope is a slight modification to the
Scope of Accreditation that does not imply the inclusion of:
a)
new parameters in the proficiency testing scheme already accredited;
b)
new proficiency testing schemes, even for the same activity area, test class and/or service group;
c)
new method for the determination of the designated value and of its associated uncertainty for an
accredited proficiency testing scheme.
Note 3: Updating the accreditation scope may consist in changing the frequency of the scheme.
8.8.3 For the case of reference material producers, the updating of scope is a slight modification to the
Scope of Accreditation that does not imply the inclusion of:
a)
new reference materials in the same subcategory of reference materials or in a new subcategory of
reference materials;
b)
new property in a produced reference material;
c)
new characterization technique of the produced reference material.
8.9 Measurement Audit
Interlaboratory comparison performed by the Metrological Reliability Sector (Secme) in order to assess
the competence of a calibration laboratory, accredited or applying for accreditation, by Cgcre, to perform
a specific calibration.

internal calibration.
8.10 Authentication
See NIT-Dicla-061.
8.11 Follow-up assessment
Assessment carried out at the facilities of CABs or their clients with the purpose of assessing the

8.21 Calibration (VIM)
Operation that, under specified conditions, in a first step, establishes a relation between the quantity
values with measurement uncertainties provided by measurement standards and corresponding
indications with associated measurement uncertainties and, in a second step, uses this information to
establish a relation for obtaining a measurement result from an indication.
Note 1: A calibration may be expressed by a statement, calibration function, calibration diagram,
calibration curve, or calibration table. In some cases, it may consist of an additive or multiplicative
correction of the indication with associated measurement uncertainty.
Note 2: Calibration should not be confused with adjustment of a measuring system, often mistakenly
called “self-calibration”, nor with verification of calibration.
Note 3: Often, the first step alone in the above definition is perceived as being calibration.

Note 2: The CMC is published in the scope of accreditation of the calibration laboratory.
Note 3: If the calibration laboratory uses more than one method to perform a given calibration or
measurement, in a specific range, the respective CMC will refer to the method by which the
laboratory obtains the lowest measurement uncertainty in this range.
