Yonkers, NY 10704, Atlantic Scale Company, Inc. + or - .03 lb. scale or balance that you are checking unless your tolerances allow otherwise. Scale Division Once the test load is determined, the grader shall use the following chart to determine whether the scale meets maintenance tolerance values. // --> That said, the tolerance of your scale, if it is made by a reputable manufacturer, will probably be around 2-3 counts, with a repeatability of <1 count (using the RSS of 10 measurements). Any tolerance that will be reflected in the certificate should be agreed first with the customer. document.write(''); A Beam balance (or Beam scale) is a device to measure weight or mass. Scale definition is - an instrument or machine for weighing. Below is a chart outlining Metric Weight Tolerances. Mechanical Tolerance Chart Data The following Engineering calculator will show the plus and minus tolerance for the specific ISO 286 Shaft tolerance data. GD&T Training Geometric Dimensioning Tolerancing Weight cart. The schematic representation of the fit is also drawn. document.write('') Tolerance for NIST Class F field standard weights used to supplement the weight cart to achieve a given test load in scale testing, from NIST HB 105-1. CHART 1B Pitch Diameter Limits for taps to 1" diameter inclusive: (Metric taps generally have more manufacturing tolerance than .0005 to the minus side.) Over 40 lbs.

D1 = Basic plus .0005 = max. These parameters are very strict so in theory you are buying an item where quality is a necessity. document.write('');
