1、Designation: C1164 14Standard 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, the year of last re
2、vision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This practice is intended for use in instances where thepurchaser desires information on the uniformity of limestone orlime
3、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 standard. The values
4、 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 standard to establ
5、ish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

8、1.4. Significance and Use4.1 This practice is designed to present in a standardizedformat information on the variability of limestone or lime froma single source over a period of time. It can be applied to allmaterials covered in Test Methods C25, C110, C1271, andC1301, and Specification C141.5. Sam
9、pling5.1 The sampling shall be done in accordance with MethodsC50.5.2 All sampling shall be performed by personnel qualifiedby specific training for this purpose.5.3 Data points shall be an average of three or more separatedeterminations relative to a specified unit of time. For example:(1) n determ
10、inations for daily average, (2) daily determinationsfor weekly average.5.4 The samples shall be identified by the date or dates thatthe represented material was obtained.6. Procedure6.1 The minimum amount of testing (see 5.3) and the typeof test(s) to be performed should be agreed upon by thepurchas
11、er and producer.NOTE 1A single daily analysis does not necessarily characterize aproduct. 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 sameperson, in order for the results to be com
12、parable.NOTE 2In order to obtain comparable results when exchangingsamples between laboratories, methods used in preparation, handling andstorage of those samples must be uniform.1This practice is under the jurisdiction of ASTM Committee C07 on Lime andLimestone and is the direct responsibility of S

United States16.2.1 When separate evaluations of a single source are madeby two or more laboratories, 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
16、different laboratories. Three or more batchesmay be necessary to obtain comparison between laboratories.6.2.2 Where a within-laboratory testing standard deviationhistory has not been established, duplicate tests made from asingle sample are required to determine the effect of testingvariation on the
17、 uniformity of results made in a singlelaboratory.7.
