1、Designation: D7910 14Standard Practice forCollection of Fungal Material From Surfaces by Tape Lift1This standard is issued under the fixed designation D7910; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision
2、. 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 practice describes the protocols for collection ofsurface samples using tape lifts and their delivery to thelaboratory.1.2 The
3、 purpose of this practice is to support the fieldinvestigator in differentiating fungal materials from non-fungalmaterial such as scuffs, soot deposits, stains, pigments, dust,efflorescence, adhesives, and water stains.1.3 The samples collected by this practice are appropriatefor either qualitative
4、or quantitative analysis by direct micros-copy.1.4 This practice does not address building occupantexposures, or occupant health risks.1.5 This practice does not address the development of aformal hypothesis or the establishment of sampling objectives.1.6 The values stated in SI units are to be rega
5、rded asstandard. No other units of measurement are included in thisstandard.1.7 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 determi
