ASTM D 4753 Document Information:
Title
Standard Guide for Evaluating, Selecting, and Specifying Balances and Standard Masses for Use in Soil, Rock, and Construction Materials Testing
ASTM International
Publication Date:
Jul 15, 2007
Scope:
This guide provides minimum requirements for general-purpose
scales, balances, and standard masses used in testing soil, rock,
and related construction materials.
This guide provides guidance for evaluating, selecting, and
specifying general purpose scales, balances, and standard masses
used in testing soil, rock, and related construction materials.
The accuracy requirements for balances and scales are specified
in terms of the combined effect of all sources of error
contributing to overall balance performance. The measurement of
specific sources of error and consideration of details pertaining
to balance construction have been intentionally avoided.
This guide does not include requirements for balances and scales
having accuracies greater than those generally required in testing
soil, rock, and related construction materials or for research
programs or specialized testing requirements.
This guide does not apply to nongraduated balances.
This guide does not address the methods used to verify or
quantify specific parameters dealing with balances and scales. For
a description of tests used in evaluating balance performance, see
NIST Handbook 44.
This guide is not intended to be used as a specification for the
purchase of balances and scales.
NOTE 1—The National Institute of Standards and Technology
(NIST), formerly the National Bureau of Standards (NBS), and the
International Organization of Legal Metrology (OIML) publish
standards or practices that specify construction requirements as
well as performance guides for balances. ASTM, OIML, and NIST
publish construction standards and tolerances for standard
masses.
NOTE 2—The terms "mass" and "determine the mass of" are used in
this standard instead of the more commonly used terms "weight" and
"weigh" to comply with standard metric practice. In addition, the
term "standard mass(es)" is used instead of standard "standard
weight(s)" when referring to a piece of material of known specified
mass used to compare or measure the mass of other masses.
This guide offers an organized collection of information or
a series of options and does not recommend a specific course of
action. This document cannot replace education or experience and
should be used in conjunction with professional judgement. Not all
aspects of this guide may be applicable in all circumstances. This
ASTM standard is not intended to represent or replace the standard
of care by which the adequacy of a given professional service must
be judged nor should this document be applied without consideration
of a project's many unique aspects. The word "Standard" in the
title of this document means only that the document has been
approved through the ASTM consensus process.
