Die Annotation des Normtextes ASTM C114-24 :
These test methods cover the chemical analyses of hydraulic cements. Specific chemical test methods are grouped as reference test methods and alternative test methods. 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. Apparatus and materials for the test method include balance, weights, glassware and laboratory containers, desiccators, filter paper, crucibles, and muffle furnace. Standard reagents for the test method shall be used within the limits of the specification. These reagents shall include purity agents, water, repackaged reagents, concentrated acids and ammonium hydroxide, nonstandardized solutions, and indicator solutions. Sample preparation and general test procedures shall be followed according to the specification. General procedures include sample weighing, taring of crucibles, weighing of ignited residues, volatilization of platinum, chemical analyses, and calculation. Reporting of analyses shall be of the following order: major components, minor components, and separate determinations. 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. 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. The standardization used for qualification and for analysis of each constituent shall be determined by valid curve-fitting procedures.
