View our weight tolerance chart for ASTM and OIML calibration weights, scale weights, and test weights.

Also, assuming the field standard test weights are being used as nominal mass standards, the maximum permissible error of the test weights must be less than one-third of the 0.001 g tolerance or 0.000333 …

The table below is a listing of the tolerances of various classes of masses. The weight value can deviate above or below the nominal value by the tolerance defined. To determine the tolerance of a mass, …

In general, industrial scales are accurate to 0.1 of one percent of the test load. Calibration We have been checking, testing, adjusting, and calibrating scales since way back in 1980. Our scale …

Using a consumer weight, such as a barbell, is not an acceptable weight to use in calibration. These weights are manufactured to a wider acceptance of tolerances, between +/-1% and +/-7%, which …

Jul 31, 2024 · To perform an accurate calibration, the accuracy of the test weights used for the calibration must be considered. Using test weights of a lower accuracy than what the scale is …

Learn about the correct tolerances and classes for check weights. Find out more in this quick 5 minute read...

When it comes to scale calibration, tolerance is the amount the weight reading on your scale can differ from the nominal value of the mass standard that has optimal accuracy.
