Reference test methods c1144 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 atsm, manganic oxide, chloride, chloroform-soluble organic substances.

CO 2 Determinations in Hydraulic Cements. The standardization used for qualification and for analysis of each constituent shall be determined by valid curve-fitting procedures. A reference test method must be used where an alternative test method is not provided. These test methods cover the chemical analyses of hydraulic cements.

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

Performance Requirements for Rapid Test Methods. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Active view ashm version of standard. Link to Active This link will always route to the current Active version of the standard. These reagents shall include purity agents, water, repackaged reagents, concentrated acids and ammonium hydroxide, nonstandardized solutions, and indicator solutions.

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.

ASTM C – 15 Standard Test Methods for Chemical Analysis of Hydraulic Cement

The reference cement is acceptable if its assigned value agrees with the average referee value within the limits given in column 3 of Table 1. 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.

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

If, however, a blank determination is desired for an alternative test method, one may be used and it need not have been obtained ashm with the analysis.

If the reference cement, as supplied, has no documented d114 of homogeneity, establish its homogeneity by analyzing at least six randomly selected samples. Recommended Order for Reporting Analyses. No further reproductions authorized. Any change in asm method procedures from those procedures listed in Sections 7—3 0 requires method qualification in accordance with 5.

Specific chemical test methods c14 provided for ease of reference for those desiring to use them. Historical Version s – view previous versions of standard.

C Interelement x114 may be used for any oxide standardization provided improved accuracy can be demonstrated when the correction is applied to all seven CRM cements. Assign the CO2 content of Standard A as the average of the two values determined, provided they agree within the required limit of Column 2. 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.

Recommended Order for Reporting Analyses. It is the responsibility aastm the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

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.

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

The reference test methods are long accepted classical chemical test methods which provide a atsm well-integrated basic scheme of analysis for hydraulic cements. Acceptable reference cements are NIST. The analyst is considered qualified when the difference between the asym results does not vary by more than the value listed in Column 2 of Table 1 and the average of the two samples asttm with the certificate value of the CRM within the limits listed in Column 3 of Table 1 after correction for minor components when needed.

Parte 1 de 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 ast, twice that value. NOTE 1—A blank determination is a procedure which follows all steps of analysis but in the absence of a sample.

ASTM C114 – 15 – Chemical Analysis of Hydraulic Cement

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. A number in parentheses indicates the year of last reapproval. Qualification for Different Analyses. Active view current version of standard Translated Standard: No certificate value given.

Specific chemical test methods are grouped as reference test methods and alternative test methods. Last previous edition approved in as C — Sample preparation asttm general test procedures shall be followed according to the specification. When Reference Methods are used, qualification testing of the analyst is required as described in 5.

Specific chemical test methods are provided for ease of reference for those desiring to use them. The reference test methods are long accepted classical chemical test methods which provide aetm reasonably well-integrated basic scheme of analysis for hydraulic cements and are also required for referee analysis in those ashm where conformance to chemical specification requirements are questioned.

Such demonstration may be made concurrently with analysis of the cement being tested. 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. General procedures include sample weighing, taring of crucibles, weighing of ignited residues, volatilization of platinum, chemical analyses, and calculation.

Satm same test methods to be used for analysis of cement being tested shall be used for analysis of the CRM cement. No other units of measurement are included in this standard.
