    ASTM E617

    Abstract

    This specification covers laboratory weights and precision mass standards including their principal physical characteristics and metrological requirements. Maximum permissible error, magnetic property, density, and surface roughness for each weight shall be within the limits indicated in this specification. Physical characteristics shall be based on construction, design, surface area, materials, magnetism, density, surface finish, weight adjustment, and marking.

    This abstract is a brief summary of the referenced standard. 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 use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    1. Scope

    1.1 This specification covers weights and mass standards used in laboratories, specifically classes 000, 00, 0, 1, 2, 3, 4, 5, 6 and 7. This specification replaces National Bureau of Standards Circular 547, Section 1, which is out of print.

    1.2 This specification contains the principal physical characteristics and metrological requirements for weights that are used.

    1.2.1 For the verification of weighing instruments;

    1.2.2 For the calibration of weights of a lower class of accuracy; and

    1.2.3 With weighing instruments.

    1.3 Maximum Permissible Errors (formerly tolerances) and design restrictions for each class are described in order that both individual weights or sets of weights can be chosen for appropriate applications.

    1.4 The values stated in SI units are to be regarded as standard.

    1.5 Weight manufacturers must be able to provide evidence that all new weights comply with specifications in this standard (e.g., material, density, magnetism, surface finish, mass values, uncertainties). Statements of compliance by calibration laboratories during subsequent calibrations must meet the requirements of ISO/IEC 17025, 5.10.4.2 and indicate on the calibration report which sections have or have not been assessed.
