Introduction With the ISO/IEC 17025 standard’s focus on risk in measurement decisions (i.e. decision rules), you should consider evaluating conformance probability. Have you ever wondered, “What is the chance that this measurement is in tolerance or out of tolerance?” No matter how great your measurement system is, results near tolerance limits make you […]
Introduction Simple acceptance is a decision rule that has been around for a long time (whether you knew what it was named or not). The best way to explain it is a set of rules used to determine whether a test or measurement result passes or fails based only on the tolerance limits. […]
Introduction Proficiency testing is an important element of ISO/IEC 17025 accreditation. So important, that it has its own ISO standard (i.e. ISO/IEC 17043). In addition to the international standard, proficiency testing has plenty of endorsement via ILAC and accreditation body policies. There is a ton of information on proficiency testing available to laboratories seeking […]
Introduction Reporting measurement uncertainty in test and calibration certificates is a common practice for ISO/IEC 17025 accredited laboratories. It is also a common problem for a lot of laboratories. Many struggle to do it right. Most accredited laboratories are required to include uncertainty in their certificates. However, many of them do not know how […]
