Mettler Toledo Calibration Weights FAQ

What is the difference between OIML and ASTM calibration weights?

OIML and ASTM are two different international standards for calibration weights. OIML classes range from E1 (highest precision) to M3 (lower precision), while ASTM classes range from Class 0 (highest precision) to Class 7 (lower precision). The choice depends on your specific application and regional requirements.

Do I need a calibration certificate with my weights?

If traceability and compliance with quality standards are important for your application, it's recommended to obtain calibration weights with an ISO/IEC 17025 certified calibration certificate. This ensures that the weights have been tested and verified against recognized standards.

How often should calibration weights be recalibrated?

The frequency of recalibration depends on factors such as usage, environmental conditions, and regulatory requirements. It's generally recommended to recalibrate weights annually or as specified by your quality management system.
