Requalification of the analyst is required every two years. The requirements for qualification of a test method and analyst are summarized in Table 2. A When seven CRM cements are required, as for demonstrating the performance of rapid test methods, at least six of the seven shall be within the prescribed limits and the seventh shall differ by no more than twice that value.

Such demonstration may be made concurrently with analysis of the cement being tested. When a lesser number of CRM cements are required, all of the values shall be within the prescribed limits.

ASTM C114 – 15 – Chemical Analysis of Hydraulic Cement

The standardization used for qualification and for analysis of each constituent shall c114 determined by valid curve-fitting procedures. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Prepare three standards, each in duplicate: A reference test method may be used in preference to an alternative test method when so desired. Specific chemical test methods are provided for ease of reference for those desiring to use them.

Link to Active This link will always route to the current Active version of the standard. It is the responsibility of the axtm of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

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.

Performance Requirements for Rapid Test Methods. The same test methods to be used for analysis of cement being tested shall be used for analysis of the CRM cement. If the two results do not agree within the permissible variation given in Table 1, the determination shall be repeated until two or three results agree within the permissible variation. No other units of measurement are included in this standard.

When Rapid Methods are used, qualification testing of both the analyst and the test method are required as described zstm 5. Specific chemical test methods are provided for ease of reference for those desiring to use them. No result shall deviate from the assigned value by more than the limits given in column 2 of Table 1.

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. This abstract is a brief summary of the referenced standard. Alternative test methods and procedures include determination of calcium oxide, calcium dioxide, magnesium oxide, loss on ignition, titanium dioxide, phosphorus pentoxide, manganic oxide, and free calcium oxide.

D Where an CRM certificate value includes a subscript number, that subscript number shall be treated as a valid significant figure. Traceability consists of documentary evidence that the assigned values of the reference. 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.

When reporting the results of referee analyses, specify which test methods were used. General procedures include sample weighing, taring of crucibles, weighing of ignited residues, volatilization of platinum, chemical analyses, and calculation.

Any test methods of demonstrated acceptable precision and bias may be used for analysis axtm hydraulic cements, including analyses for referee and certification purposes, as explained in Section 4. Performance Requirements for Rapid Test Methods. CO 2 Determinations in Hydraulic Cements. Link to Active This link will always route to the current Active version of the standard. If the reference asstm, as supplied, has no documented guarantee of homogeneity, establish its homogeneity by analyzing at least six randomly selected samples.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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 4.

Longer, more complex procedures, in some instances, have been retained as alternative test methods to permit comparison of results by different procedures or for use when unusual materials are being examined, where unusual interferences may be suspected, or when unusual preparation for analysis is required.

It is used for detection and compensation of systematic bias. This standard is issued under the fixed designation C; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. When Reference Methods are used, qualification testing of the analyst is required as described in 5.

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. The reference cement must have an assigned value for the analyte being determined. 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.

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 4.
