4.2 A swab sample collected according to this practice is intended to be used to assess fungal material on surfaces.
4.3 A swab sample collected from an area with defined dimensions can be used to quantify fungal material per unit area or for qualitative analysis.
4.4 A swab sample collected from point(s) of interest can be used for qualitative analysis or to quantify fungal material per sample.
4.5 A swab sample collected according to this standard practice can be analyzed by direct microscopy, culture, or biochemical analysis.
1.1 The purpose of this standard practice is to describe the procedures for collection of surface samples using sterile swabs.
1.2 The purpose of this standard practice is to support the field investigator in differentiating fungal materials from non-fungal material such as scuffs, soot deposits, stains, pigments, dust, efflorescence, adhesives, dust, and water stains.
