Medical Mask Bacterial filtration test ASTM F2101
ASTM F2101 specifies the method for testing of different face mask materials for Bacterial filtration efficiency using Staphylococcus aureus aerosol as the challenging micro-organism. The BFE value is reported as percentage efficiency at 3.0-microns for ASTM levels 1, 2, and 3.
The standard method ASTM F2101 specifies a test for determining Bacterial Filtration Efficiency (BFE) of medical face mask materials. The testing principle is to subject the face side of the mask to an aerosol containing droplets of 3.0-microns size inoculated with Staphylococcus Aureus,at a prescribed flow rate that corresponds to normal human respiration. BFE is computed from the ratio of upstream bacterial challenge to downstream residual concentration. The ASTM F2101 test method also permits testing with the liner side of the face mask being subjected to bacterial challenge. The results of the test are useful in evaluating the protection offered by various specimens of medical masks against patient generated as well as externally generated bacterial aerosols. BFE values of medical masks are rated at ASTM levels 1,2 and 3, depending on the criticality of the application.
The apparatus broadly comprises a testing column with aerosol generator and liquid dosing pump on the top and detector at the bottom, with associated controls and instrumentation.
The ASTM F2101 specifies the following key requirements for the BFE test:
Aerosol type: Staphylococcus aureus bacteria in 3.0-microns size droplets with minimum particle count of 2200 ±500 viable particles per test.
Flow rate: 28 litres per minute
Aerosol detector: Six Stage Viable Particle Cascade Impactor
Test Time: 2 minute particle exposure per test
The specimens may be pre-conditioned by storage, flexing and abrasion, wetting with water or alcohol, to simulate realistic usage scenarios. or washing and folding. Since infectious organisms are involved, trained personnel shall conduct the test ensuring laboratory and personnel safety.
Medical face masks of standard size are subjected to the test.
The ASTM F2101 BFE value is reported as percentage efficiency at 3.0 micron for ASTM levels 1, 2, 3.
ASTM E572 test method covers the analysis of stainless and alloy steels by Wavelength Dispersive X-ray Fluorescence Spectrometry (WDXRF). It provides rapid, multi-element determinations with sufficient accuracy to assure product quality.
The ASTM D2674 test is a standard test method for the analysis of sulfochromate etch solutions used in the surface preparation of aluminum. The ASTM D2674 standard specifies a method for determining the efficacy of an etchant used to prepare the surface of aluminum alloys for subsequent adhesive bonding.
An immunological method for quantization of Hevea Natural Rubber (HNRL) proteins using rabbit anti-HNRL serum. Rabbits immunized with HNRL proteins react to the majority of the proteins present, and their sera have the capability to detect most if not all the proteins in HNRL.
ASTM G65 measures the resistance of metallic materials to abrasion using the dry sand/rubber wheel apparatus. The quality, durability, and toughness of the sample are determined using this test. Metallic materials are ranked in their resistance to scratching abrasion under a controlled environment.
ASTM E2141 test methods provide accelerated aging and monitoring of the performance of time-dependent electrochromic devices (ECD) integrated in insulating glass units (IGU). This test helps to understand the relative serviceability of electrochromic glazings applied on ECD.
ASTM C724 test method is used in analyzing the quality and ease of maintenance of a ceramic decoration on architectural-type glass. This test method is useful in the acknowledgment of technical standards.
