For regulated QC and testing laboratories, weighing compliance is about more than just accurate readings. Many labs pass daily testing but fail audits because of gaps in equipment credentials, calibration traceability or record keeping — even when the equipment itself works fine.
Using uncertified weighing equipment is one of the top audit non-conformances. For regulated industries, the equipment you use must meet relevant international standards for accuracy, safety and consistency.
Purchase equipment from reputable manufacturers with complete certifications
Verify equipment specifications match your application requirements
Keep product documentation and certification files on file for audit
Calibration itself is not enough — it must be traceable to recognized measurement standards.
Use only certified traceable reference weights
Calibrate across the full operating range, not just a single point
Follow a risk-based calibration schedule
Record measurement uncertainty where required
Even if equipment is calibrated correctly, missing records will fail an audit.
Keep all calibration certificates linked to individual equipment
Document calibration dates, operators and results
Maintain maintenance and repair records
Schedule regular internal audits of weighing equipment
❌ Using uncertified scales for regulated QC testing ❌ Calibrating with weights without traceable certificates ❌ Single-point calibration instead of full-range verification ❌ No documented calibration schedule ❌ Incomplete or disorganized records
Use certified weighing equipment from qualified manufacturers
Establish scheduled traceable calibration
Keep complete, organized records
Conduct periodic internal checks
