Anotace textu normy ASTM C1005-20 :
This specification covers the minimum requirements for scales, balances, reference masses, and glass graduates used in the physical testing of hydraulic cements. Requirements for analytical reference masses and balances are not included in this specification. Reference masses for use in the methods of physical testing of hydraulic cement and related and similar materials shall conform at least to the requirements of Class 6 reference masses given in this specification. The maintenance tolerances given in this specification for Class 6 reference masses are to be considered acceptance tolerances for purposes of this specification and the maintenance tolerances twice these values. Requirements for scales, balances, and glass graduates shall conform at least to the requirements for capacity, precision and accuracy, readability, and sensitivity.
Keywords:
devices for determining mass, devices for measuring volume, glass graduate, reference masses ,, ICS Number Code 17.060 (Measurement of volume, mass, density, viscosity)

1.1?This specification covers the minimum requirements for scales, balances, reference masses, and glass graduates used in the physical testing of hydraulic cements. 1.2?Requirements for analytical reference masses and balances are not included in this specification, but are to be found in Test Methods C114. The use of restrictive terminology, classes, ranges, and so forth has been intentionally avoided to allow the use of this specification by other standards-writing bodies with similar requirements for reference masses and devices for determining mass, if desired. 1.3?These requirements are not sufficiently descriptive to be used as the sole specifications for the purchase of reference masses or devices for determining mass without amplification. 1.4?Values in SI units shall be obtained by measurement in SI units or by appropriate conversion, using the Rules for Conversion and Rounding given in IEEE/ASTM SI10, of measurement made in other units. 1.5?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
