Calibration Weight Care
When using laboratory balance calibration weights, also referred to as mass standards, for laboratory or calibration applications, the proper care, handling, and usage are extremely critical in maintaining the traceability and accuracy of the weights. It is essential that the weight maintain its accuracy, especially if they are ASTM Class 0, ASTM Class 1, Ultra […]
Weight Checks for Laboratory Balances
The first thing that needs to be determined is what calibration weights are needed. This entails choosing the calibration weight class, weight range, and weight test points. Ideally, a weight should be more accurate than the weighing (test) instrument, though this is not always possible. Whenever possible, the calibration weight range should bracket the user […]
Figuring out the Accuracy Classes
This is a quick guide and background on weight accuracy classifications for your balance calibration weight (i.e. mass standards) to ensure traceable and accurate weighing measurement & calibrations. When choosing balance calibration weights for your weighing and measurement application, the first thing that needs to be addressed is what accuracy class will be needed. Accuracy […]
