Scope of Accreditation

Primo is ISO/IEC 17025

Calibration reports from A2LA certified laboratories ensure national and international recognition of a laboratory’s competence to perform specific calibrations.

Calibration laboratories certified by A2LA offer measurements that are verified traceable to the International System of Units (SI).

Laboratories accredited by A2LA  are issued a certificate, and a detailed scope of calibration capabilities which lists the types of measurements that have been assessed by measurement experts. The scope also lists the laboratory’s best measurement capabilities.

Calibration certificates from Accredited laboratories can eliminate the redundant assessments and
audits of calibration laboratories that are done to meet the requirements of customers and quality system registrars.

Traceability of measurements to the SI provides the basis for fair trade, increased global market acceptance of test reports and products, enhanced product quality, and demonstration of conformance to the principles of such international quality standards as ISO 9001:2000.

A2LA metrologists or other measurement experts verify that  A2LA-certified laboratories are competent to perform specific calibrations.

Management system specialists assess A2LA-certified laboratories to verify that a suitable management system is in place.
