ASTM F2101 - Standard Test Method for Evaluating the Bacterial Filtration Efficiency (BFE) of Medical Face Mask Materials, Using a Biological Aerosol of Staphylococcus aureus
This test method is used to measure the bacterial filtration efficiency (BFE) of medical face mask materials, employing a ratio of the upstream bacterial challenge to downstream residual concentration to determine filtration efficiency of medical face mask materials. This test method is a quantitative method that allows filtration efficiency for medical face mask materials to be determined. The maximum filtration efficiency that can be determined by this method is 99.9 %. This test method does not apply to all forms or conditions of biological aerosol exposure. Users of the test method should...
ASTM F2100 - 11(2018) - Standard Specification for Performance of Materials Used in Medical Face Masks
This specification covers the classifications, performance requirements, and test methods for the materials used in the construction of medical face masks that are used in health care services such as surgery and patient care. Medical face mask material performance is based on testing for bacterial filtration efficiency, differential pressure, sub-micron particulate filtration efficiency, resistance to penetration by synthetic blood, and flammability. This specification does not address all aspects of medical face mask design and performance, the effectiveness of medical face mask designs as related...
Performance of Facepiece Respirators and Surgical Masks Against Surgical Smoke
Simulated Workplace Protection Factor Study Objective: Surgical smoke generated during electrocautery contains toxins which may cause adverse health effects to operating room (OR) personnel. The objective of this study was to investigate the performance of surgical masks (SMs), which are routinely used in ORs, more efficient N95 surgical mask respirator (SMRs) and N100 filtering facepiece respirator (FFRs), against surgical smoke. Methods: Ten subjects were recruited to perform surgical dissections on animal tissue in a simulated OR chamber, using a standard electrocautery device, generating surgical...
