(Guide)Standard Guide for Nuclear Surface Moisture and Density Gauge Calibration Facility Setup
Standard Guide for Nuclear Surface Moisture and Density Gauge Calibration Facility Setup
SIGNIFICANCE AND USE
Gauge calibration is conducted for the following purposes:
To ensure gauge measurement repeatability between gauges
To correct for electronic and mechanical changes over time
To adjust readings after major service to the gauge
To establish a proper calibration area for gauges
To reduce the chance of improper calibration
Note 1—The quality of the results produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria of practice D3740 are generally considered capable of competent and objective testing/inspection/etc. Users of this standard are cautioned that compliance with practice D3740 does not in itself assure a means of evaluating some of those factors.
SCOPE
1.1 This guide outlines procedures for setup of nuclear moisture density gauge in shielded, Method A, and unshielded, Method B, configurations.
1.2 This guide does not attempt to describe the calibration techniques or methods. It is assumed that this guide will be used by persons familiar with the operations of the gauge and in performing proper calibration, service and maintenance.
1.3 This guide does not attempt to address maintenance or service procedures related to the gauge.
1.4 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.
1.5 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 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. The word “Standard” in the title of this document has been approved through ASTM consensus process.
1.6 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in practice D6026.
1.6.1 The method used to specify how data are collected, calculated, or recorded in this standard is not directly related to the accuracy to which the data can be applied in the design or other uses, or both. How one applies the results obtained using this standard is beyond its scope.
