The body of the weight is the primary piece and the knob of the weight is the secondary piece. And in almost every case, these are tighter — have a lower tolerance — than commercial ammunition. The printed weight is within 60 pounds of scale display. You can take the required accuracy and perform a calculation to see if the balance scale you are using has the proper readability for the minimum weight. Similarly the tolerances achiev-able with fixed forms, sliding forms and other types of forming systems can differ. The catch weight unit is the unit by which the the item is weighed and invoiced. 5.67 - .227 = 5.443g for the min weight, yours is 5.48g just above the minimum weight, the lighter than spec weight (but within tolerance) is due to the wear it has seen during its time in commerce. For scales which have been in service for at least three months, a "Maintenance Tolerance" of 0.1% of the total test weight is used. Tolerances are used to control the amount of variation inherent in all manufactured parts. Tolerance is being patient, understanding and accepting of anything different. To have a decent assurance that the weight is real within the bounds of your variability introduced via the uncertainty in your checkweigher; you should really say a weight is correct passing over a checkweigher if it is within +/- 3 sigma which is approx.
