1、Designation: C114 11b1C114 13Standard Test Methods forChemical Analysis of Hydraulic Cement1This standard is issued under the fixed designation C114; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A numb
2、er in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1 NOTEEq 14 was corrected editorially in August 2013.1. Scope*1.1 These test methods cover the chemical analyses of hydraulic cements. Any test methods
3、 of demonstrated acceptableprecision and bias may be used for analysis of hydraulic cements, including analyses for referee and certification purposes, asexplained in Section 4. Specific chemical test methods are provided for ease of reference for those desiring to use them. They aregrouped as Refer
4、ence Test Methods andAlternative Test Methods. The reference test methods are long accepted classical chemicaltest methods which provide a reasonably well-integrated basic scheme of analysis for hydraulic cements. The alternative testmethods generally provide individual determination of specific ana
5、lytes and may be used alone or as alternates and determinationswithin the basic scheme at the option of the analyst and as indicated in the individual method.1.2 Contents: Contents:Section Subject2 Referenced Documents4 Description of Referee Analyses4.1 Referee Analyses5 Qualification for Different

When two or three results do agree within the permissible variation, their average shall be accepted as thecorrect value.
