Full Description

1.1 This guide describes the process and objective of calibrating the density system of a nuclear surface moisture and density gauge, or formulating the mathematical relationship between the density system response (the density count) of a nuclear surface moisture and density gauge and the corresponding density value of the density standard upon which the density system response was observed.

1.2 This guide describes the process and objective of calibrating the water content system of a nuclear surface moisture and density gauge, or formulating the mathematical relationship between the water content system response (the water content count) of a nuclear surface moisture and density gauge and the corresponding water mass per unit volume value of the water content standard upon which the water content system response was observed.

1.3 This guide describes the process and objective of verifying the density system of a nuclear surface moisture and density gauge.

1.4 This guide describes the process and objective of verifying the water content system of a nuclear surface moisture and density gauge.

1.5 This guide describes two mathematical processes by which the gauge measurement precision may be computed or measured.

1.6 This guide offers guidance for developing and reporting estimates of uncertainties in measurements made with gauges that have undergone calibration or verification.

1.7 All observed and calculated values shall confirm to the guide for significant digits and rounding established in Practice D6026.

1.8 This guide does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this guide to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

1.9 This guide offers an organized collection of information or a series of options and does not recommend specific course of action. This document cannot replace education or experience and should be used in conjunction with professional judgment. 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.
