Testing and calibration laboratories are liable to record and document their measurement equipment in regards to installation, maintenance and testing the proper function. In addition, they must also prove that instruments are maintained, qualified regularly and function properly.

The following statements are taken from the literature "Complying with ISO 17025 – A Practical Guidebook" [2] which are relevant in regards to service and testing of measuring:

Commissioning of new equipment (referring to section 5.5.2 in ISO17025)

All new equipment must be checked for correct functioning before being placed in routine service. This should include checks against the manufacturer's specifications and checks to confirm that the equipment gives satisfactory results when used to make the measurements for which it is intended.

Service and calibration schedule (referring to section 5.5.2 in ISO17025)

Before introducing any piece of equipment into service, the management should decide upon a service/maintenance, calibration and performance checking schedule. This will normally be a combination of service from the supplier and in-house checks and calibrations.

This raises the questions: how are mass comparators tested, qualified and calibrated?

This white paper answers this question in detail by covering the following topics:

  • Types of mass comparators
  • How are mass comparators tested and certified?
  • Testing parameters for mass comparators
  • Mass comparator certificate
  • Necessity of maintenance, qualification and certification
