1. Scope 1.1 The purpose of this standard practice is to describe good and customary procedures for the collection of surface samples for assessing the presence of settled fungal spores and/or the identification of suspect fungal growth. 1.2 This standard practice includes sampling procedures to determine the presence of fungal particulate and associated structures in deposited dust on building materials, finishes, and other indoor surfaces as well as the identification of suspect fungal growth. 1.3 This standard practice is not intended to limit the user from the collection of other surface particulate that may be captured through this technique that may be of interest. 1.4 This standard practice for sampling for fungal spores is intended to support efforts of practitioners performing building assessments for fungal growth and/or fungal particulate contamination. 1.5 These practices do not cover methods used to assess airborne concentrations of fungal bioaerosols (spores, hyphal fragments, MVOCs), building occupant exposures, or occupant health risks. 1.6 The purpose of this standard practice is to support the field investigator in differentiating fungal growth and mold damaged building materials from scuffs, soot deposits, stains, pigments, dust, efflorescence, adhesives, dust, water stains, etc. 1.7 This standard practice presumes that the user has a fundamental understanding of field investigative techniques related to the scientific process, and a basic understanding of sampling plan development and implementation. It is important to establish the related hypothesis to be tested and the supporting analytical methodology needed in order to identify the sampling media to be used and the laboratory conditions for analysis. 1.8 This standard guide does not address the development of a formal hypothesis or the establishment of appropriate and defensible investigation and sampling objectives (ISOs). It is presumed the investigator has the experience and knowledge base to address these issues. 1.9 This standard practice does not provide the user sufficient information to allow for extensive interpretation of the analytical results from sample collection. It is the users obligation to seek or obtain the information and knowledge necessary to interpret the results of the sample collection data. 1.10 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
