Designation:D733814Standard Guide forAssessment Of Fungal Growth in Buildings1This standard is issued under the fixed designation D7338;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 guide provides a compendium of information and amenu of options for assessment of fungal growth in buildings,but does not recommend a specific course of action.Due to thewide variety of fungal problems affecting buildings and theiroccupants,and the wide variety of buildings,it is not possibleto describe a set of uniform steps that will always be performedduring an assessment(that is,a standard practice);therefore theuser of this guide must decide which steps are appropriate fora given situation or building.1.2 This guide is specific to fungal growth,which is onlyone potential problem in a building environment.It may be partof,but is not intended to take the place of,a comprehensiveindoor air quality investigation.1.3 This guide describes minimum steps and procedures forcollecting background information on a building in question,procedures for evaluating the potential for moisture infiltrationor collection,procedures for inspection for suspect fungalgrowth,and procedures beyond the scope of a basic survey thatmay be useful for specific problems.1.4 Assessments for fungal growth may be useful whereverfungal growth is suspected,excess moisture has been presentor when there are concerns regarding potential fungal growth.1.5 Periodic fungal assessment in buildings may be acomponent of preventative maintenance programs.1.6 This guide is applicable to buildings including residen-tial(for example,single or multi-family),institutional(forexample,schools,hospitals),government,public assembly,commercial(for example,office,retail),and industrial facili-ties.1.7 Recommendations for developing a sampling strategy ormethods for the collection and analysis of fungal samples arebeyond the scope of this guide.For recommendations fordeveloping a sampling strategy,see Ref(1)2,Chapter 10.1.8 Recommendations for remediation of fungal growth arebeyond the scope of this guide.1.9 This guide is not intended to supersede any governmentregulations governing the assessment of fungal growth inbuildings.1.10 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:3C755 Practice for Selection of Water Vapor Retarders forThermal InsulationC1699 Test Method for Moisture Retention Curves of Po-rous Building Materials Using Pressure PlatesD653 Terminology Relating to Soil,Rock,and ContainedFluidsD4442 Test Methods for Direct Moisture Content Measure-ment of Wood and Wood-Base MaterialsE331 Test Method for Water Penetration of ExteriorWindows,Skylights,Doors,and Curtain Walls by Uni-form Static Air Pressure DifferenceE547 Test Method for Water Penetration of ExteriorWindows,Skylights,Doors,and Curtain Walls by CyclicStatic Air Pressure DifferenceE631 Terminology of Building ConstructionsE1105 Test Method for Field Determination of Water Pen-etration of Installed Exterior Windows,Skylights,Doors,and Curtain Walls,by Uniform or Cyclic Static AirPressure DifferenceE1186 Practices for Air Leakage Site Detection in BuildingEnvelopes and Air Barrier SystemsE1356 Test Method for Assignment of the Glass TransitionTemperatures by Differential Scanning CalorimetryE2128 Guide for Evaluating Water Leakage of BuildingWalls1This guide is under the jurisdiction of ASTM Committee D22 on Air Qualityand is the direct responsibility of Subcommittee D22.08 on Sampling and Analysisof Mold.Current edition approved June 1,2014.Published July 2014.Originally approvedin 2010.Last previous edition approved in 2010 as D7338 10.DOI:10.1520/D7338-14.2The boldface numbers in parentheses refer to a list of references at the end ofthis standard.3For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 E2270 Practice for Periodic Inspection of Building Facadesfor Unsafe Conditions2.2 Non-ASTM Standards:ANSI/GEI Standard MMS1001 Mold and Moisture Man-agement Standard for New Construction3.Terminology3.1 Definitions:3.1.1 building envelope,nthe outer elements of abuilding,both above and below ground,which divide theexternal from the internal environments.Commonly includedare exterior walls,windows,door
