Protective Clothing Tester Wet Microorganism Bacterial Penetration Resistance Tester Apparatus: used to measure the penetration performance of bacteria in the liquid when the material is subjected to mechanical friction (the shielding performance of the liquid against bacterial penetration by the mechanical friction chamber)
EN ISO 22610, EN 14126, Annex A, YY/T 0506.6
Automatic stop as preset counters.
High stable testing performance from precise structure design.
Stainless steel body provides high corrosion resistant performance.
Adjustable loading pressure.
Rotary speed: (60 plusmn; 1)rpm
The test refers to the pressure on the material: (3plusmn;0.02)N
Outward wheel speed: 5~6 rpm
Timer set range: 0~99.99min
The inner and outer ring weights: (800plusmn;1)g
Place the specimen on AGAR plate. A piece of the same specification is placed on the specimen. Cover with a high density polyethylene film about 10 microns thick. The three layers of material using the cone steel ring (the test material below, the mushroom center, high density polyethylene film on top) are stuck together. Place the ring on the AGAR plate on the turntable. The experiment means that the material can be applied to the material in a way that can be moved on the surface of the whole plate, so that the material is subjected to the combination of pressure and friction.
This model can simulate the force condition of the barrier material in the actual application and the microorganism penetration under the wet conditions.
The microbes on the microbial migrate to the surface of the AGAR plate after penetrating the experimental material. Through the culture and colony count of AGAR plate, the penetration performance of the test material can be quantitatively evaluated.
