>>>>QCSS CURRENT SCOPE AND CERT<<<< 

 

a2lalogo20new205 07On July 16, 2002 Quality Control Sales and Services, Inc. was accredited to meet the requirements of the International Standard ISO/IEC 17025:2005 and ANSI/NCSL Z540-1-1994 by A2LA. This accreditation was the result of months of diligently analyzing our calibration services and fine-tuning them to the requirements of these standards. Through hard work and management commitment, Quality Control Sales and Services, Inc. passed the technical competence assessment and received our accreditation.

CLICK HERE to view our certificate and scope of accreditation. We have recently had our A2LA assessment and are in the process of getting our certificate updated. As of now this is an extension good through October 2018. The final certificate will be uploaded as soon as it is received. 

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

In February 1999, Quality Control was granted registration of our Quality Management System to the requirements of ISO 9002 by 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 own 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.

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 microinch, 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.
