ASTM F2053 - 00(2017) - Standard Guide for Documenting the Results of Airborne ,Particle, Penetration Testing ,of Protective Clothing, Materials Conformity Assessment Notes This ,test, method provides specific ,test, techniques for both manufacturers and users to evaluate materials when exposed to aerosol ,particle, sizes between 0.1 and 5.0 pm.

The standard EN 1073-2 is used to define the requirements and ,test, methods for determining the performance ,of protective clothing, used in environments with radioactive particulates. The ,test, method also measures the inward leakage of particulates into the whole suit, which is then expressed as its nominal ,protection, factor (NPF).

The number of bacterial aerosol droplets that come into contact with the ,filter, medium is determined by performing ,test, controls in the ,test, system without the ,filter, medium. Difficulty controls are maintained at 3.0-0.3 colony forming units (CFU) with an average ,particle, size (MPS) of 1700 ± 3000 µm.
