In November 2019 the PTA Branding was enhanced for the PTA Final reports.  The final reports now include the International Laboratory Accreditation, Mutual Recognition Arrangement (ILAC MRA) logo as part of the IANZ logo for PTA’s accreditation for proficiency testing providers. 

PTA is accredited by International Accreditation New Zealand.  This accreditation is for a proficiency testing provider to the requirements of ISO/IEC 17043 Conformity assessment - General requirements for proficiency testing


An extract from the ILAC website for background information:

The ILAC Mutual Recognition Arrangement (ILAC MRA) provides significant technical underpinning to the calibration, testing, medical testing and inspection results and provision of proficiency testing programs of the accredited conformity assessment bodies that in turn delivers confidence in the acceptance of results.

The ILAC MRA supports the provision of local or national services, such as providing safe food and clean drinking water, providing energy, delivering health and social care or maintaining an unpolluted environment.

In addition, the ILAC MRA enhances the acceptance of products across national borders. By removing the need for additional calibration, testing, medical testing and/or inspection of imports and exports, technical barriers to trade are reduced. In this way the ILAC MRA promotes international trade and the free-trade goal of “accredited once, accepted everywhere” can be realized.
