ASTM D7788-14(2023)

4.1?This practice is intended for the collection of airborne fungal spores or fragments, or both, using inertial impaction.

4.2?It is the responsibility of the user to assure that they are in compliance with all local, state and federal regulations governing the inspection of buildings for fungal colonization and the collection of associated samples.

4.3?This practice is intended to provide the user with a basic understanding of the equipment, materials and instructions necessary to effectively collect air samples using an inertial impactor.

4.4?This practice, when properly executed, may also be used for the evaluation of other types of airborne particles with the capturing characteristics appropriate for inertial impactor, and for which appropriate analytical methods exist. Such particles may include dust mites, skin cells, pollen, and other materials.

1.1?The purpose of this practice is to describe procedures for the collection of airborne fungal spores or fragments, or both, using inertial impaction sampling techniques.

1.2?This 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 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 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 practice does not provide the user sufficient information to allow for interpretation of the analytical results from sample collection. It is the user's 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. No other units of measurement are included in this standard.

1.7?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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.8?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
