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 1Practice 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.

3.1 Accurate elemental analyses of samples of petroleum and petroleum products are required for the determination of chemical properties, which are in turn used to establish compliance with commercial and regulatory specifications.1.1 This practice covers information relating to sampling, calibration and validation of X-ray fluorescence instruments for elemental analysis, including all kinds of wavelength dispersive (WDXRF) and energy dispersive (EDXRF) techniques. This practice includes sampling issues such as the selection of storage vessels, transportation, and sub-sampling. Treatment, assembly, and handling of technique-specific sample holders and cups are also included. Technique-specific requirements during analytical measurement and validation of measurement for the determination of trace elements in samples of petroleum and petroleum products are described. For sample mixing, refer to Practice D5854. Petroleum products covered in this practice are considered to be a single phase and exhibit Newtonian characteristics at the point of samp
