The GWP™ Certificate annex to the Accuracy Calibration Certificate (ACC) sets a new benchmark in weighing by:

• Linking the performance of your balance or scale to your specific processes
• Giving you the certainty that your device meets your individual requirements
• Including as-found and as-left test results
• Showing your safe weighing range with a visual representation

This gives you peace of mind that your balance or scale is fit for purpose and supplies you with the proper documentation to prove it. It is based on the principles of Good Weighing Practice™, or GWP™, and is set up according to EURAMET cg-18.

The accuracy of weighing devices becomes less reliable over time and can therefore impact your business success. Only onsite calibration in the environment where the balance or scale is used allows you to assess how reliable your weighing results are.
