Accredited Calibration Cert

On July 16, 2002, QCSS was accredited to meet the requirements of the International Standard ISO/IEC 17025:2005 and ANSI/NCSL Z540-1-1994 by A2LA. This accreditation resulted from months of diligently analyzing our calibration services and fine-tuning them to the requirements of these standards. 

Through hard work and management commitment, QCSS passed the technical competence assessment and received our accreditation.

The American Association for Laboratory Accreditation (A2LA) is a non-profit, professional membership society committed to the success of laboratories through the administration of a laboratory accreditation system and training courses on laboratory practices.


In February 1999, QCSS was granted registration of our Quality Management System to the requirements of ISO 9002 by the Quality Certification Bureau of Edmonton, Alberta, Canada. Our first goal was accomplished on schedule.

At the request of our valued QS9000 registered customers and for our commitment to continually evaluate and improve the quality of our calibration services, our second goal was to be accredited to ISO/IEC Guide 25 by the American Association of Laboratory Accreditation (A2LA) within the following year. ISO/IEC Guide 25, in contrast with ISO/QS9000, is a technical competency standard specifically written to assess calibration and testing laboratories, as opposed to a generic quality system. Accreditation to ISO/IEC Guide 25-1990 and ANSI/NCSL Z540-1-1994 is a requirement of laboratories providing external calibration services to QS9000 companies.


Human Hair Diagram

Q: What is a micro-inch or a micron?
A: In our shop, we use a simple diagram to show the size difference between a human hair, a micro inch, and a micron.

Q: What is uncertainty?
A: The calculation of uncertainty for a measurement is an effort to set reasonable bounds for the measurement result according to standardized rules. Since every measurement produces only an estimate of the answer, the primary requisite of an uncertainty statement is to inform the reader of how sure the writer is that the answer is in a certain range.

Q: What is traceability?
A: Traceability is the property of the result of a measurement or the value of a standard whereby it can be related to stated references, usually national or international standards, through an unbroken chain of comparisons, all having stated uncertainties.
