It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its astm e617 and astm e617. Note-Although metric weights are almost exclusively used in laboratories, tolerances are given in this specification for nonmetric weights in U.

Physical characteristics shall be based on construction, design, surface area, materials, magnetism, density, surface finish, weight adjustment, and marking.
It is anticipated that as metrication, even in test laboratories, proceeds further, the nonmetric tables given in this specification will become astm e617. Weights used for commercial measurements are excluded, except that one class of standards designed for the calibration of commercial test weights is included.
Maximum permissible error, magnetic property, density, and surface roughness for each weight shall be within the limits indicated in this specification. Tolerances astm e617 design restrictions for each class are described in order astm e617 both satm weights or sets of weights can be chosen for appropriate applications see Note.
