Designation:E 2119 00Standard Practice forQuality Systems for Conducting In Situ Measurements ofLead Content in Paint or Other Coatings Using Field-Portable X-Ray Fluorescence(XRF)Devices1This standard is issued under the fixed designation E 2119;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon(e)indicates an editorial change since the last revision or reapproval.1.Scope1.1 This practice covers the collection and documentation ofquality control(QC)measurements for determining acceptablelevels of instrumental performance when using field-portableenergy-dispersive x-ray fluorescence spectrometry devices(XRFs)for the purposes of generating lead classificationresults from measurements on paint and other coating filmswithin buildings and related structures.1.2 QC procedures covered in this provisional practiceinclude the performance of calibration checks,substrate biaschecks,and specific instructions for documenting the collecteddata for later use in reporting the results.1.3 No detailed operating instructions are provided becauseof differences among the various makes and models of suitableinstruments.Instead,the analyst is to follow the instructionsprovided by the manufacturer of the particular XRF device orother relevant sources of information on XRF operation.1.4 This practice contains notes which are explanatory andare not part of the mandatory requirements of this provisionalpractice.1.5 The values stated in SI units are to be regarded as thestandard.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 establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:E 1583 Practice for Evaluating Laboratories Engaged in theDetermination of Lead in Paint,Dust,Airborne Particu-lates,and Soil inAround Buildings and Related Structures2E 1605 Terminology Relating to Abatement of Hazardsfrom Lead-Based Paint in Buildings and Related Struc-tures3E 1613 Test Method for Analysis of Digested Samples forLead by Inductively Coupled Plasm Atomic EmissionsSpectrometry(ICP-AES),Flame Atomic Absorption(FAAS),or Graphite Furnace Atomic Absorption(GFAAS)Techniques3E 1645 Practice for Preparation of Dried Paint Samples forSubsequent Lead Analysis by Atomic Spectrometry3E 1729 Practice for Field Collection of Dried Paint Samplesfor Lead Determination by Atomic Spectrometry Tech-niques32.2Other Document:Guidelines for the Evaluation and Control of Lead-BasedPaint Hazards in Housing43.Terminology3.1 DefinitionsFor definition of terms not presented be-low,refer to Terminology E 1605.3.2 Definitions of Terms Specific to This Standard:3.2.1 building component,npart or element of a buildingthat is made of an industry product that is manufactured as anindependent unit and is capable of being joined with otherelements.Examples include doors,walls,baseboard and exte-rior siding.3.2.2 calibration check,na procedure that generates a QCmeasurement using a calibration test sample with one type ofcontrol block(usually wood).3.2.3 calibration mode,na selected operating mode thatpermits adjustment of an instruments calibration.3.2.4 calibration test sample,na test film sample of aknown lead level in mg/cm2,which must have a reporteduncertainty of the lead level.Calibration test samples may beseparate from a substrate or adhered to a substrate.All1This practice is under the jurisdiction ofASTM Committee E-6 on Performanceof Buildings and is the direct responsibility of Subcommittee E06.23 on Abatementof Hazards from Lead in Buildings and Related Structures.Current edition approved Nov.10,2000.Published March 2001.Originallypublished as PS 95 98.Last previous edition PS 95 98.2Discontinued 1998.See 1997 Annual Book of ASTM Standards,Vol 04.11.3Annual Book of ASTM Standards,Vol 04.11.4Available from the U.S.Department of Housing and Urban Development,Washington,DC 20410,www.hud.gov/lea.1Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959,United States.calibration test samples shall be traceable to the NationalInstitute of Standards and Technology(NIST)standard refer-ence materials and have a known specified uncertainty in theknown lead level.3.2.5 continuing calibration check,na calibration checkperformed during the testing day after the initial calibrationcheck.A continuing calibration check also can serve as a finalcalibration check.3.2.6 control block,na small block of material of anidentifiable substrate type used to simulate a building materialduring QC measurements.3.2.7 display unit,nan electronic device that presents theresults of an XRF measurement to the user.Other parameterssuch as total measurement time also may be pre
