3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
Anti-pollen performance polenproofproperty
Fabric masks to prevent pollen grains and their products through the performance, expressed as a percentage by pollen.
Principle 4
The fabric is applied to the air flow through the fabric attraction pollen falls on the filter paper was calculated based on the quality of flowers attract airflow before and after the filter paper
Powder transmittance, in order to characterize the anti-pollen performance of the fabric.
5 Equipment and Materials
5.1 pollen transmission tester, by the suction pump, flow meter and screw-type filter composed of (see Figure 1), shall meet the following requirements.
--- Aspirator maximum suction pressure to 27kPa;
--- Meter range of 3L/min ~ 30L/min;
--- Screw-type filter made of a plastic funnel, filter sheet, and a bottomless glass composition, funnel diameter 25mm, the upper end of a side wall about
5mm wide longitudinal incision. Filter sheet on the bottom of the funnel inner diameter of about 23mm, which can effectively prevent the particle size of less than 10μm
Particles through, but without prejudice to the airflow. Bottomless glass may tighten in the inverted funnel. To prevent gas leakage in the hopper
Placed inside a rubber gasket.
