ASTM-F318 › Standard Practice for Sampling Airborne Particulate Contamination in Cleanrooms for Handling Aerospace Fluids
Show Complete Document History
The following bibliographic material is provided to assist you with your purchasing decision:
This practice establishes the standard procedures (including apparatus, reagents, and materials to be used) for taking samples of airborne particulate matter in a specific area in the aerospace industry, commonly called the cleanroom, where aerospace fluids are handled. This practiced is based on the impingement of particles on a filter membrane using a vacuum technique. The number of air samples required in a given area will depend on the geometric floor area, the disturbance to the uninterrupted airflow pattern, and the room volume.
1.1 This practice covers a procedure for sampling airborne particulate matter larger than 5 m in size. The method is designed to be used in specific areas, commonly called cleanrooms in the aerospace industry, where aerospace fluids are handled.Note 1
Practice F 50 is an alternative procedure.
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.
