Introduction to Measurement Uncertainty

In the world of metrology, measurement uncertainty and its level of impact on calibration plays a huge role in decisions about what products to purchase, along with who to receive calibration services from. Minimizing measurement uncertainty is key for anyone making critical measurements, but many may be confused about what measurement uncertainty is and how to determine the significance of an assigned value.

ISO/IEC 17025 Calibration in Food and Agriculture

World Accreditation Day

Yesterday (June 9, 2020) marked this year’s World Accreditation Day, which is a global initiative established by the International Laboratory Accreditation Cooperation (ILAC) and the International Accreditation Forum (IAF) to promote the value of accreditation.

This year’s focus was on how accreditation improves food safety, supporting the confidence of consumers, suppliers, purchasers, regulators and specifiers in the quality and safety of food [1]. When it comes to ensuring food safety, consumers and suppliers rely on their equipment and calibration providers to comply with the appropriate international standards, such as ISO/IEC 17025:2017. 

Attaining accreditation status to ISO/IEC 17025:2017 is a rigorous process that ensures that the technical competence of personnel, the ethics of personnel, and the reliability of the organization itself are at a level that can be recognized on an international scale. The Dwyer Instruments, Inc. Engineering Laboratory is proud to be able to provide ISO/IEC 17025:2017, ANSI/NCSL Z540-1-1994 and ANSI/NCSL Z540.3 Section 5.3 accredited calibrations on pressure products that are used in these critical food safety environments.

Certificates of Calibration Explained

Dwyer Instruments, Inc. offers a variety of calibration services for new or previously purchased products. In 2019, the Dwyer Instruments, Inc. – Engineering Laboratory, located in Michigan City, IN, gained accreditation to ISO/IEC 17025:2017 through the ANSI National Accreditation Board. The Dwyer lab now offers two different types of calibration certificates for our products: a certificate of NIST calibration and an ISO/IEC 17025:2017 accredited certificate of calibration. Now that accredited calibration services are available for select Dwyer products, it is important to know the differences between these two different calibration certificates. Knowing these differences will allow you to understand which calibration certificate will best suit your needs. Continue reading “Certificates of Calibration Explained”
