5 Steps to Manage Quality in a Regulated Environment METTLER TOLEDO’s GWP ® stands for Good Weighing Practice. It offers a framework to establish a weighing practice that works. Here are the five basic tenets of GWP ® : Each step involves assessment of process parameters to ensure equipment can meet tolerances and quality requirements. STEP 1: Good Evaluation STEP 3: Good Installation STEP 5: Good Operation STEP 2: Good Selection STEP 4: Good Calibration Evaluating the process from a metrological perspective to establish parameters, such as smallest net weight and required process accuracy. The parameters set expectations for a given instrument. Documenting that appropriate installation – unpacking, set-up, configuration, calibration, adjustment and operator training – has taken place and that the equipment still fulfills selection requirements. Establishing SOPs and test schedules to guarantee weighing – process criteria are fulfilled between service visits. Selecting a scale fulfilling the preceding requirements or matching accuracy to process needs. The minimum weight concept is used as a basis for selection. Calibrating a scale in its operating environment. Documenting scale performance and issuing applicable certificates at regular intervals is the qualified technician’s task.
