ASTM E – 97 Standard Specification for Laboratory Weights And Precision Mass Standards
This specification covers laboratory weights and precision mass standards including their principal physical characteristics and metrological requirements. Active view current version of standard. Referenced Documents purchase separately The documents listed below are referenced astm e617 the subject standard but are not astm e617 as part of the standard.
Historical Version s – view previous versions of standard. Physical characteristics shall be based on construction, design, surface area, materials, magnetism, density, surface finish, weight adjustment, and marking.
This specification replaces National Astm e617 of Standards CircularSection 1, which is out of print. Maximum permissible error, magnetic property, density, and surface roughness for each weight shall be within the limits indicated in this specification.
ASTM does not give any warranty express or implied or make any astm e617 that the contents of this abstract are accurate, complete or up to date.
Weights used for commercial measurements are excluded, except that one class of standards designed for the calibration of commercial test weights is included. It is informational only and astmm an astm e617 part of the standard; the full text of the standard itself must be referred astm e617 for its use and application.
Tolerances and design restrictions for each class are described in order that both individual weights astm e617 sets of weights can be chosen for appropriate applications see Note. It is anticipated that as metrication, even in test laboratories, proceeds further, the nonmetric tables given in this specification will become obsolete.

Note-Although metric weights are almost astm e617 used in laboratories, tolerances are given in this specification for nonmetric weights in U.
Where appropriate, it is recommended that these International Recommendations be used. This abstract is a brief summary of the referenced astm e617. Work Item s – proposed revisions of this standard.

In general, this specification replaces, astm e617 function, National Bureau of Standards CircularSection 1, which is out of print.
