Revision to Important ILAC Documents

ILAC has recently revised two important documents, namely ILAC P10 and ILAC P14. These documents are available for download from the ILAC website. The NAB-MALTA is currently reviewing its system to verify whether any changes to its policies are needed.

ILAC P10 - ILAC Policy on the Traceability of Measurement Results

This document describes the ILAC policy with regard to the metrological traceability requirements from ISO/IEC 17025:2005 and ISO 15189:2007. This policy may also be applied to other conformity assessment activities where testing and/or calibration is involved (e.g., inspection and product certification).

For calibrations performed by a laboratory in order to establish metrological traceability for its own activities, and which are not a part of the laboratory’s scope of accreditation, the ILAC policy in section 2 is applicable. Internal calibrations are also known as “In-house” calibrations.

Metrological traceability of measurement results is a key topic for which a harmonised policy is needed if the market is to have confidence in calibrations, testing and inspections performed by accredited laboratories and inspection bodies covered by the EA MLA Arrangement. Metrological traceability requires an unbroken chain of calibrations to stated references, all having stated uncertainties

 The date of implementation of ILAC P10:01/2013 is January 2014.

 ILAC P14 - ILAC Policy for Uncertainty in Calibration

 This policy document addresses the estimation of uncertainty of measurement and its expression on calibration certificates of accredited laboratories and the evaluation of the Calibration and Measurement Capability (CMC) on the scopes of accreditation in line with the principles agreed upon between ILAC and the BIPM.

 This policy sets out the requirements and guidelines for the estimation and statement of uncertainty in calibration and measurement, which apply to accreditation bodies and their accredited laboratories and reference material producers that perform calibration and measurement, in order to ensure a harmonised interpretation of the GUM and the consistent use of CMC by ILAC member bodies to strengthen the credibility of EA MLA Arrangement.

 This document is effective from the date of publication.
