ISO Calibration Vs. Non-ISO Calibration

ISO Calibration Vs. Non-ISO Calibration

Today’s blog is all about ISO calibration versus non-ISO calibration processes.

All ISO 9001 accredited organizations will require them to develop a calibration system that conforms to the standard requirements of ISO 9001. The versatility of the ISO standard could cover plenty of processes, and calibration is a big one. Read on to learn all about ISO calibration versus non-ISO calibration processes.

The Procedure for Calibration Using 9001

Clause 7.1.5 of ISO 9001:2005 defines the different requirements for calibration in ISO 9001 and is known as the Monitoring and Measuring Resources for ISO 9001. This standard doesn’t provide the actual procedure for calibrating but outlines the requirements an organization must follow. Each organization can pick its way of fulfilling these various requirements. The requirements can be summarized as follows:

  • Calibration before usage
  • Calibration records and notes
  • Calibration Frequency
  • ISO Certified Laboratory – ISO 17025 accredited

The mandatory requirements for ISO 9001 certified organizations to calibrate their laboratory instruments that are accredited to ISO standard 17025. The focus is personnel expertise, equipment selection, documented procedures, validity, and measured tolerance levels. While selecting an ISO 17025 accredited lab, ask for their ISO certificate indicating the right accreditation level, the scope of work, and the period for a valid certification.

Calibration Before Lab Use

Calibration or Installation Qualification IQOQ is a requirement before you can use a new er instrument. Instruments may not provide correct measurements if they are used before calibration. Instruments should have calibration labels with dates to indicate calibration status and the next due date. 

Methods and Frequency

Correct calibration frequency activity is important, as it directs the device’s performance. The ISO standard doesn’t provide any calibration frequency for any valid device. Instead, it depends on the organization’s methodology for the frequency. Typically, there are two main methods to define a frequency. One method is to set the frequency by consultation with the manufacturer’s guidelines. One other method depends upon the device usage. If the device is used quite frequently, then the frequency is more often, and if the device isn’t frequently used, it can be calibrated less often.
