If you require stable processes, improving quality, lean laboratory and/or regulatory compliance, use Good Weighing Practice™ (GWP®) as your benchmark. GWP is a unique science-based methodology for reducing risk when selecting, calibrating and operating new or existing weighing equipment.
GWP improves quality while increasing efficiency and lowering costs. It helps ensure that you are compliant with both local and international standards such as Weights and Measures, ISO9001:2015, FSMA and FDA.
GWP Recommendation is a free service to help you select the right weighing device by matching its metrological performance to your exact measurement needs; you receive a science-based product analysis based on your budget and quality targets. Each GWP Recommendation report includes minimum weight and safety factor calculations to confirm that you have selected the right device for your process.
Calibrating a balance tells you that it meets your specifications. GWP Verification goes further by proving that your balance meets both your process requirements and compliance obligations.
GWP Verification methodology also determines appropriate maintenance and calibration cycles based on answers to simple risk questions. In addition, you are provided with correct test weights, tolerances and in-house tests (SOPs) for your maintenance and metrology departments. Audit-proof documentation ensures continuous measurement accuracy throughout your product's life cycle.
Do your weighing SOPs meet today's international quality standards and are they aligned with USP, GLP, OIML, ISO,…? Are different facilities using different procedures? Many organizations find their SOPs are out of step with new regulations and should be updated through professional SOP writing. Modernized SOPs take into account risk, tolerances, calibration and adjustment cycles, test weights, routine testing, smallest net weight and operator training. Introduce scientifically-sound weighing equipment management based on SOPs written by the world’s metrology and compliance experts.
Good Weighing Practice™ (GWP®) - Science Based Standard for Weighing
This paper introduces GWP®, the science-based global standard for efficient lifecycle management of weighing systems. Selection of the appropriate weighing system is based on the evaluation of weighing process requirements providing scientific guidance for testing and calibrating weighing instruments.
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.
Legal metrology sets very strict requirements for weighing instruments and their usage in a legal for trade applications. However, Legal metrology today sets the minimum standards for trade and does not address the need for high quality, compliance and profitability. This paper will help you to understand the shortcomings of legal metrology and describes complementary actions to maintain quality according your own process tolerance.
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.
