Based on the requirement of ISO 17025, if you need to judge whether the instrument has passed or fail based on tolerance limit or acceptance criteria, you need to account for the measurement uncertainty before making judgments or conformity assessment.
What is ISO 17025? The ISO 17025 standard specifies the general require-ments for the competence of calibration laboratories to carry out tests and calibrations. A pipette calibration laboratory with ISO 17025 accreditation provides the highest level of reliability and confidence in pipette calibration, as proven by the uncertainty of measure-

Define Specifications from the Calibration Results; Account for the measurement uncertainty; Identify the Zone for acceptance and Rejection; State the Decision Rule; Use the decision Rule – Decide for conformity
ISO 17025 is a specific standard detailing requirements for the technical competency of calibration laboratories. ISO 17025 shares many of the same principles as ISO 9001, however goes much further, and focuses more closely on management structure and processes in a calibration lab.
Learn about intermediate checks per ISO 17025 (AKA “verification”) vs calibration. Plus, tips for incorporating them to prevent costly manufacturing recalls.
What Is Calibration Tolerance and How Do I Calculate It? Calibration tolerance is defined by the International Society of Automation (ISA) as “permissible deviation from a specified value; may be expressed in measurement units, percent of span, or percent of reading.“
22 godz. temu · For example, ISO 9001 is a quality standard that requires certified companies to calibrate their measurement equipment, plus document the processes and procedures involved. ISO/IEC 17025 is the quality standard that calibration laboratories use to ensure they produce valid results.
