When two or three results do agree within the permissible variation, their average shall be accepted as the correct ast. Description of Referee Analyses. Active asstm current version of standard Translated Standard: Maximum difference between the duplicate CO 2 values for Standards B and C, respectively, shall be 0. For the purpose of comparing analyses and calculating the average of acceptable results, the percentages shall be calculated to the nearest 0. The final results, when corrected for blank values, should, in either case, be so designated.

The alternative test methods generally provide individual determination of specific components and may be used alone or as alternates and determinations within the basic scheme at the option of the analyst and as indicated in the individual method.

Any test methods of demonstrated acceptable precision and bias may be used for analysis of hydraulic cements, including analyses for referee and certification purposes, as explained in Section 3. Reporting of analyses shall be of the following order: It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Performance Requirements for Rapid Test Methods. When an average of either two or three results can be calculated, the calculation shall be based on the three results.

ASTM C114 – 15 – Chemical Analysis of Hydraulic Cement

NOTE 1—A blank determination is a procedure which follows all steps of analysis but in the absence of a sample. Qualification for Different Analyses.

The reference test methods are long accepted classical chemical test methods which provide a reasonably well-integrated basic scheme of analysis for hydraulic cements and are also required for referee analysis in those cases where conformance to chemical specification requirements are questioned. If, however, a blank determination is desired for an alternative test method, one may be used and it need not have been obtained concurrently with the analysis.

CO 2 Determinations in Hydraulic Cements. Specific chemical test methods are grouped as reference test methods and alternative test methods. The alternative test methods generally provide individual determination of specific analytes and may be used alone or as alternates and determinations within the basic scheme at the option of the analyst and as indicated in the individual method. A number in parentheses indicates the year of last reapproval. A cement shall not be rejected for failure to conform to chemical requirements unless all determinations of constituents involved and all necessary separations prior to the determination of any one constituent are made entirely by these methods.

Specific chemical test methods are provided for ease of reference for those desiring to use them. The reference cement must have an assigned value for the analyte being determined. The reference test methods are long accepted classical chemical test methods which provide a reasonably well-integrated basic scheme of analysis for hydraulic cements. Prepare three standards, each in duplicate: NOTE 3—It is not intended that the use of reference test methods be confined to referee analysis.

Reference test methods and procedures include determination of insoluble residue, silicon dioxide, ammonium hydroxide group, ferric oxide, phosphorus pentoxide, titanium dioxide, zinc oxide, aluminum oxide, calcium oxide, magnesium oxide, sulfur, loss on ignition, sodium and potassium oxides, manganic oxide, chloride, chloroform-soluble organic substances.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided asmt part of the standard. A reference test method must be used where an alternative test method is not provided. Repeat the determinations until a set of duplicate results agree within the permissible variations. The alternative test methods generally provide individual determination of specific analytes and may be used alone or as alternates and determinations within the basic scheme at the option of the analyst and as indicated in the individual method.

ASTM C – 18 Standard Test Methods for Chemical Analysis of Hydraulic Cement

The reference test methods that follow in Sections 7—2 2, or other test methods qualified according to 5. To demonstrate traceability for a given analyte, perform a referee analysis as defined in 4. The requirements for qualification of a test method and analyst are summarized in Table 2.

When Rapid Methods are used, qualification testing of both the analyst and the test method are required as described in 5. D Where an CRM certificate value includes a subscript number, that subscript sstm shall be treated as a valid significant figure.

Standard reagents for the test method shall be used within the limits of the specification. Performance C14 for Rapid Test Methods. The individual analyst must demonstrate achievement of acceptable precision and bias, as explained in Section 3, when these test methods are used. The same test methods to be used for analysis of cement being tested shall be used for analysis of the CRM cement.

Any test awtm of demonstrated acceptable precision and bias may be used for analysis of hydraulic cements, including analyses for referee and certification purposes, as explained in Section 4.

Material CRM must be used in the qualification of test methods and analysts. The analyst is considered qualified when the difference between the duplicate results does not vary by more than the value listed in Column 2 of Table 1 and the average of the two samples agrees with the certificate value of the CRM within the limits listed in Column 3 of Table 1 after correction for minor components when needed.

When a c11 number of CRM cements are required, all of the values shall be within the prescribed limits. Active view current version of standard. Specific chemical test methods are provided for ease of reference for those desiring to use them. General procedures include sample weighing, taring of crucibles, weighing of ignited residues, volatilization of platinum, chemical analyses, and calculation.
