1、Designation:D501389(Reapproved 2009)Standard Practices forSampling Wastes from Pipes and Other Point Discharges1This standard is issued under the fixed designation D5013;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of las
2、t 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 Those practices provide guidance for obtaining samplesof waste at discharge points from pipes,sluiceways,conduits,and conveyor
3、 belts.The following are included:SectionsPractice ALiquid or Slurry DischargesPractice BSolid or Semisolid Discharges7 through 910 through 121.2 These practices are intended for situations in whichthere are no other applicable ASTM sampling methods(seePractices D140 and D75)for the specific industr
4、y.1.3 These practices do not address flow and time-proportional samplers and other automatic sampling devices.1.4 Samples are taken from a flowing waste stream ormoving waste mass and,therefore,are descriptive only withina certain period.The length of the period for which a sample isdescriptive will
5、 depend on the sampling frequency and com-positing scheme.1.5 It is recommended that these practices be used inconjunction with Guide D4687.1.6 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 e

8、(1)knowledge of the processes producing the stream,or(2)the results of a preliminary investigation of the wastestreams variability.A sampling design is then developed thatconsiders the waste streams variability,the time frame thesample is to represent,and the precision and accuracy requiredfor waste
9、 analysis or testing.The actual sampling procedureconsists of obtaining several grab samples from the movingstream or mass for analysis or testing.4.Significance and Use4.1 The procedure outlined in these practices are guides forobtaining descriptive samples of solid,semisolid and liquidwaste from f
10、lowing streams,and incorporate many of the sameprocedures and equipment covered in the Referenced Docu-ments.These practices by themselves will not necessarilyresult in the collection of samples representative of the totalwaste mass.The degree to which samples describe a wastemass must be estimated
11、by application of appropriate statisticalmethods and measures of quality assurance.It is recommendedthat those practices be used in conjunction with Guide D4687.5.Hazards5.1 In all sampling practices,safety should be the firstconsideration.Personnel involved in the sampling should befully aware of,a
12、nd take precautions against,the presence oftoxic or corrosive gases,the potential for contact with toxic orcorrosive liquids or solids,and the dangers of moving belts,conveyors,or other mechanical equipment.Guidance on wastesampling safety can be found in Guide D4687.6.Sampling Design6.1 The frequen
13、cy of sampling and the number of compos-ites required to obtain a sample of the waste will depend on thefollowing:6.1.1 Time variability of the waste composition,1These practices are under the jurisdiction of ASTM Committee D34 on WasteManagement and are the direct responsibility of Subcommittee D34
