1.Signed on November 2, 2000; Entered into force on November 2,2000.
The International Laboratory Accreditation Cooperation (ILAC)
denotes the collaboration of Accreditation Bodies that conduct
and administer accreditation systems of calibration laboratories
and testing laboratories.

This document describes the elements of a Mutual Recognition Ar-
rangement (Arrangement) for testing and calibration laboratory
accreditation as a means by which the signatories to the ILAC
Arrangement for testing and calibration can recognise one anoth-
er's accredited laboratories. This Mutual Recognition Arrangeme-
nt (hereinafter referred to as the Arrangement) is a major
co-operative effort to enhance the objective of free trade thro-
ughout the world.

The criteria for the operation of accredited laboratories and
for the operation of the Accreditation Bodies are currently spe-
cified respectively in ISO/IEC 17025, December 1999 (and future
versions thereof) and in ISO/IEC Guide 58 (and future versions
thereof), supplemented by ILAC application documents if necessa-

The principal elements for establishing confidence among the pa-
rticipating systems within ILAC are listed below. These elemen-
ts are designed to ensure conformance with the requirements in
order to establish and maintain mutual confidence in the techni-
cal competence of ILAC members and their accredited laboratories
. The elements are:

1.Exchange of information on the development and operation of
ILAC member accreditation schemes;
2.Participation in the work and decision making of the ILAC Gen-
eral Assembly and ILAC Committees where applicable.
3.Participation in international interlaboratory comparisons and
proficiency testing programs;
4.Participation in the work of ILAC Expert Groups and Task Forc-
es held to discuss problems related to testing and calibration
in various technical fields.
5.Evaluations of applicants and re-evaluations of signatories to
this Arrangement are conducted in accordance with the relevant
ILAC and regional cooperation documents;
6.Observations of applicant bodies' and signatories' assessments
of their laboratories to determine if these laboratories meet
the requirements of ISO/IEC 17025, December 1999 (and future
versions thereof);
7.Confidence in the metrology institutes of the signatory econo-
mies to which traceability is claimed by accredited laborator-
ies and support for the measurement comparison activities of
BIPM* and/or regional metrology organisations.

This Arrangement does not affect other recognition required by
laws and regulations in the economies of the signatory bodies.
