Significance and Use
4.1 This practice provides a procedure for collecting surface material using a sterile swab.
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.
Scope
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.
1.3 This practice does not address building occupant exposures, or occupant health risks.
1.4 The samples collected by this practice are appropriate for culture, direct microscopy, and/or biochemical analysis.
1.5 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 determine the applicability of regulatory limitations prior to use.
Domestic orders are delivered via United Parcel Service (UPS) or United States Postal Service (USPS). Transit
times average 3 to 5 business days. Please be aware that UPS will not deliver packages to Post Office Boxes.
International orders are delivered via courier post services which can be either a postal service, courier
service, or a combination of both. Standard Service is untraceable. Please allow 4-7 weeks for delivery.
Please be aware that carriers will not deliver packages to Post Office Boxes. Because of the variability of
customs processes and procedures in different countries, ASTM International cannot guarantee transit times to
international destinations. Customs duty and taxes are the responsibility of the consignee.
