1、Designation:E172810Standard Practice forCollection of Settled Dust Samples Using Wipe SamplingMethods for Subsequent Lead Determination1This standard is issued under the fixed designation E1728;the number immediately following the designation indicates the year oforiginal adoption or,in the case of
2、revision,the 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 covers the collection of settled dust onsurfaces using the wipe sampling method.These sa
3、mples arecollected in a manner that will permit subsequent extractionand determination of lead using laboratory analysis techniquessuch as atomic spectrometry or electroanalysis.1.2 This practice does not address the sampling designcriteria(that is,sampling plan which includes the number andlocation
4、 of samples)that are used for clearance,lead hazardevaluation,risk assessment,and other purposes.To provide forvalid conclusions,sufficient numbers of samples should beobtained as directed by a sampling plan.1.3 This practice contains notes that are explanatory and arenot part of the mandatory requi
5、rements of this practice.1.4 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.5 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 stand
