What does OIML Class E2, F1, or F2 mean?

These classifications refer to the accuracy and tolerance levels of the weight, as defined by the International Organisation of Legal Metrology (OIML). E2 weights offer the highest precision, followed by F1 and F2, suitable for different levels of calibration requirements.

Is an ISO 17025:2017 Certificate of Calibration necessary?

An ISO 17025:2017 certificate provides documented proof of traceability to national and international standards, which is crucial for quality assurance, regulatory compliance, and maintaining audit trails in many industries.

How should calibration weights be handled and stored?

Calibration weights should be handled with gloves to prevent contamination from oils and dirt, and stored in their protective cases in a stable environment to maintain their accuracy and prolong their lifespan.

Can these weights be re-calibrated?

Yes, calibration weights should be periodically re-calibrated by an accredited laboratory to ensure their continued accuracy and compliance with relevant standards. The frequency depends on usage and quality system requirements.

What is the difference between a Statement of Accuracy and an ISO 17025 certificate?

A Statement of Accuracy typically confirms the weight meets its nominal value within a specified tolerance. An ISO 17025 certificate provides a more comprehensive report from an accredited laboratory, including measurement uncertainty and full traceability, offering a higher level of confidence.
