The accuracy of weighing devices in laboratories and production can become less reliable over time, substantially affecting a company’s business success. Inconsistent product quality, reputational damage, and financial and legal consequences can all stem from uncalibrated devices and a lack of routine testing.
Calibration of your weighing devices is needed to maintain accuracy and avoid the consequences of inaccurate measurements. Routine testing of balances and scales between calibrations is necessary to maintain reliable results over time.
Only an onsite calibration in the environment where a balance or scale is used allows you to assess how reliable weighing results are. Our Accuracy Calibration Certificate (ACC) is a state-of-the-art calibration service. It offers various tolerance assessments to analyze your calibration results – giving you concrete results you can use.
USP Chapter 41 and Ph. Eur. Chapter 2.1.7. describe the importance not only of calibration but also of including a statement of measurement uncertainty. In combination with the Accuracy Calibration Certificate (ACC), our Pharmacopoeia certificates provide you with the physical evidence of compliance according to these important USP and Ph. Eur. Chapters.
How can you be sure your weighing results remain accurate between calibrations? Proper routine testing performed by the user gives you both peace of mind and the documentation you need.
However, to test your devices properly, test frequency, methods, weights and tolerances need to be defined.
Do you know how often your balances and scales need to be calibrated? Are you sure about the details of your routine testing plan?
Based on a risk assessment of your weighing process and performance, our GWP® Verification service provides you with a solid routine testing and calibration action plan.

To assess the performance of your balances and scales, an onsite calibration by a Service Technician must be performed.
Between regularly scheduled calibrations, routine testing of balances and scales should be performed by the user. To do so effectively, a routine testing plan must be defined that includes test frequency, methods, weights and tolerances.
