1. Scope*
  1.1 These test methods cover the chemical analyses ofhydraulic cements. Any test methods of demonstrated accept-able precision and bias may be used for analysis of hydrauliccements, including analyses for referee and certification pur-poses, as explained in Section 3. Specific chemical testmethods are provided for ease of reference for those desiring touse them. They are grouped as Reference Test Methods and Alternative Test Methods. The reference test methods are longaccepted classical chemical test methods which provide areasonably well-integrated basic scheme of analysis for hy-draulic cements. The alternative test methods generally provide individual determination of specific analytes and may be usedalone or as alternates and determinations within the basicscheme at the option of the analyst and as indicated in theindividual method.
