2、n.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 produced a
3、t 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 given in parent
4、heses 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 establish appro-priate sa

8、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.Sampling5.1 The sampling shall be done
9、 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 determinations for daily average,(2)daily d
10、eterminationsfor 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 thepurchaser and producer.NOTE1A single daily analysi
11、s 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 comparable.NOTE2In order to obtain comparable resu
12、lts 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 Subcommittee C07.02 on Specifica-tions and Guidelin
