CYLINDRICAL FOR TESTING OF HIGH CAPACITY WEIGHING MACHINE
Standard Weights as per OIML R 47 are used for testing (and adjusting) of high capacity weighing machines in accuracy classes of medium and ordinary. SWPI’s Standard Weights are made of high quality cast iron and are free from sharp edges and corners. The closures of adjusting cavity are watertight and airtight. Weights are protected by a durable coat of paint generally black. These weights are suitable for stacking and rolling.
MEDIUM ACCURACY CLASS CAST IRON CYLINDRICAL
SWPI’s Cast Iron Test Weights are intended for use in the Verification or Calibration of Weights and for use with weighing instruments of medium accuracy class or ordinary class. They are manufactured from high quality cast iron that meets ANSI/ASTM E617 hardness requirements and surface roughness requirements and are free of cracks and pits. Weights with nominal values from 100g to 10kg have the shape of cylindrical with knob rounded edges. There is an adjusting cavity placed as per drawing. Lead is used for the adjustments of the accuracy of mass. Weights are protected by a durable coat of paint-generally black colour to protect the casting from rusting.
