Quality Assurance
A comprehensive quality assurance system is an essential component of a reputable test and measurement service. We have independent accreditation of our quality assurance system for the methods we routinely use through the National Association of Testing Authorities (NATA) (Accreditation No 14881).
The NATA website explains the benefits of using accredited services and how to intepret NATA endorsed reports. Click here to view the NATA website. You may view our listing under Chemical Testing in WA.
Stack-Air ensures all sampling is conducted in accordance with the appropriate method, and it is fully documented and traceable.
Analysis is conducted by independent NATA-accredited laboratories, or in-house where accredited. Equipment is regularly calibrated and the details recorded in calibration and maintenance logbooks.
Stack-Air has employed a qualified independent consultant to produce electronic algorithms and thus ensure the correct calculation of results.
