Good Weighing Practice™ (GWP®)

This white paper aims to:

• explain the changes in the revised standard of ISO 9001:2015,
• look at the effect of these changes on weighing devices and weighing processes,
• provide guidance and recommendations on how to consider weighing devices in order to meet the process requirements and risk-based thinking approach outlined in the revised version of ISO 9001,
• introduce the firmly established Good Weighing Practice™ strategy which fully supports the risk-based process approach and explain how this already complies with ISO 9001:2015.

This document provides a clear definition that defines what calibration (based on international standards) and how it differs from the adjustment of a weighing device.  While the concept of calibration and adjustment applies to all measurement device types, this paper focuses specifically on weighing devices.

Do the end products, or manufactured goods, meet your customer’s high quality standards, and can it be proven?
To avoid mistakes, the best approach is not to rely on weights-and-measures or manufacturers’ specifications as the sole purchase criteria. Instead, consider using your weighing process tolerance to select and operate the right device.
