1、Designation: C1164 92 (Reapproved 2009)Standard Practice forEvaluation of Limestone or Lime Uniformity From a SingleSource1This standard is issued under the fixed designation C1164; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, t

2、he year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice is intended for use in instances where thepurchaser desires information on the uniformity of

3、limestone orlime produced at a single source. It is intended that this testmethod normally be used for the predominant material manu-factured at a plant. Guidelines for sampling, testing andpresentation of results (Table 1) are given.1.2 The values stated in inch-pound units are to be regardedas sta

4、ndard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this s

Procedure6.1 The minimum amount of testing (see 5.3) and the typeof test(s) to be perf

A minimum of three analyses is more reasonable.6.2 It is desirable that all tests used in a single evaluation beperformed in the same laboratory, preferably by the samep

16、erson, in order for the results to be comparable.NOTE 2In order to obtain comparable results when exchangingsamples between laboratories, methods used in preparation, handling andstorage of those samples must be uniform.6.2.1 When separate evaluations of a single source are madeby two or more labora

17、tories, additional tests of a standardmaterial or exchanged portions of the same sample may benecessary to determine differences in testing that are likely tobe obtained in the different laboratories.
