Designation:D729721Standard Practice forEvaluating Residential Indoor Air Quality Concerns1This standard is issued under the fixed designation D7297;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()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This standard practice describes procedures for evaluat-ing indoor air quality(IAQ)concerns in residential buildings.1.2 The practice primarily addresses IAQ concerns encoun-tered in single-family detached and attached(for example,townhouse or duplex design)residential buildings.Limitedguidance is also provided for low-and high-rise multifamilydwellings,such as condominiums and apartments.1.3 The IAQ evaluation procedures are comprised of inter-views with the homeowner or resident(s)(including telephoneinterviews and face-to-face meetings)and on-site investiga-tions(including walk-through,assessment,and measure-ments).For application practicality,these procedures are di-vided into three separate phases,which may occur over one ormore site visits.1.4 The procedures described in this standard practice areaimed at identifying potential causes contributing to an IAQissue or concern.Such findings can be the basis for recom-mending corrective measures.This standard practice does notdescribe problem resolution or corrective measures,and thestandard is not intended to evaluate the impact of correctivemeasures.1.5 This practice describes a pathway for characterizingindoor air,though using this practice does not guarantee that aninvestigator will be able to identify or resolve an IAQcomplaint for one or more of the following reasons:(1)thediversity of sources and contaminants in indoor air;(2)otherfactors that may affect occupant perception and acceptance ofindoor air quality,such as air temperature,humidity,noise,lighting,and psychological stress;(3)the range of susceptibil-ity in the population.1.6 Implementation of procedures given in this standardrequires the investigator(or investigative team)to have ad-equate background in several areas:general principles of IAQ;interviewing techniques;building design and constructionpractices;basic understanding of heating and cooling systemsand appliances;use of IAQ measurement equipment;interpre-tation of IAQ data;and technical report writing.1.7 Although many elements described in this standardpractice may be useful in training of IAQ investigators,itshould not be used as the sole basis for specifying orconducting such training.1.8 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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.For additional safety precautionary information,see Section 6.1.9 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2D1356 Terminology Relating to Sampling and Analysis ofAtmospheresD1357 Practice for Planning the Sampling of the AmbientAtmosphereD4861 Practice for Sampling and Selection of AnalyticalTechniques for Pesticides and Polychlorinated Biphenylsin Air(Withdrawn 2021)3D5197 Test Method for Determination of Formaldehyde andOther Carbonyl Compounds inAir(Active Sampler Meth-odology)D5438 Practice for Collection of Floor Dust for ChemicalAnalysisD5466 Test Method for Determination of Volatile OrganicCompounds in Atmospheres(Canister Sampling,MassSpectrometry Analysis Methodology)D5952 Guide for the Inspection of Water Systems for1This practice is under the jurisdiction ofASTM Committee D22 on Air Qualityand is the direct responsibility of Subcommittee D22.05 on Indoor Air.Current edition approved Sept.1,2021.Published October 2021.Originallyapproved in 2006.Last previous edition approved in 2014 as D7297 14.DOI:10.1520/D7297-21.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3The last approved version of this historical standard is referenced onwww.astm.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organizat
