ASTM WK22872

    Work Item: ASTM WK22872 - New Practice for Collection of Total Airborne Fungal Spores via Inertial Impaction Methodology

    (What is a Work Item?)

    Developed by Subcommittee: D22.08 | Committee D22 | Contact Staff Manager



    1. Scope

    1. Scope 1.1 The purpose of this standard practice is to describe procedures for the collection of airborne fungal spores and/or fragments using inertial impaction sampling techniques. 1.2 This standard practice is not intended to limit the user from the collection of other airborne particulates that may be of interest and captured through this technique. 1.3 This standard practice presumes that the user has a fundamental understanding of field investigative techniques related to the scientific process, and 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. 1.4 This standard practice does not address the development of a formal hypothesis or the establishment of appropriate and defensible investigation and sampling objectives. It is presumed the investigator has the experience and knowledge base to address these issues. 1.5 This standard practice does not provide the user sufficient information to allow for interpretation of the analytical results from sample collection. It is the users responsibility to seek or obtain the information and knowledge necessary to interpret the sample results reported by the laboratory. 1.6 The values stated in SI units are to be regarded as standard.

    This has been an active work item in the past (WK9298) that died in committee from failed attention by me. When the D22.08 sampling task group held its first meeting in Reno, Nevada, April 2004, priorities for developing standard practices for the collection of mold in air and surfaces were established. The non-culturable slit impaction method was selected as first priority because the group acknowledged it to be a widely used method. Also, this is a companion document to the non-culturable inertial impaction analytical method that has been submitted for ballot by the D22.08 analytical task group. The end users are field professionals collecting samples for airborne mold spores.
