1、Designation:C175217Standard Guide forMeasuring Physical and Rheological Properties ofRadioactive Solutions,Slurries,and Sludges1This standard is issued under the fixed designation C1752;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision
2、,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 Intent:1.1.1 The intent of this guide is to provide guidance for themeasurement and calculation of physical an
3、d rheologicalproperties of radioactive solutions,slurries,and sludges as wellas simulants designed to model the properties of these radio-active materials.1.2 Applicability:1.2.1 This guide is intended for measurement of mass andvolume of the solution,slurries,and sludges as well asdissolved solids
4、content in the liquid fraction and solids contentassociated with the slurries and sludges.Particle size distribu-tion is also measured.1.2.2 This guide identifies the data required and the equa-tions recommended for calculation of density(bulk,settledsolids,supernatant,and centrifuged solids),settli
5、ng rate,vol-ume and weight percent of the centrifuged solids and settledsolids,and the weight percent undissolved solids,dissolvedsolids,and total oxides.1.2.3 This guide is intended for measurement of shearstrength and shear stress as a function of shear rate.1.2.4 Rheological property measurement
6、guidelines in thisguide are limited to rotational rheometers.1.2.5 This guide is limited to measurements of viscous andincipient flow and does not include oscillatory rheometry.1.3 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.
7、1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.1.5 This internati
