YS-227Y Bacteriophage Penetration Tester (4-Station)
【Scope of Application】:
Performs high-pressure penetration testing on products.
【Compliant Standards】:
1. ASTM F1671 Standard Test Method for Resistance of Materials Used in Protective Clothing to Penetration by Blood-Borne Pathogens Using Phi-X174 Bacteriophage Penetration as a Test System,
2. YY/T 0689-2008 Test method for resistance of protective clothing materials to penetration by blood-borne pathogens using Phi-X174 bacteriophage,
3. YY/T 0700-2008 Test method for resistance of protective clothing materials to penetration by synthetic blood,
4. GB/T 19082-2009 Technical requirements for medical disposable protective clothing.
【Instrument Features】:
1. Uses compressed air; silent air pump.
2. Positive pressure sensor for real-time monitoring.
3. Precision pressure regulating valve for stepless adjustment (pressure hold time/configurable).
4. Adjustable spray time; automated operation.
5. Clamping device for easy sample handling.
6. Sample loading/unloading: Ratchet torque wrench (13.6N.m), convenient & torque-controlled.
7. HMI operation; touchscreen shows real-time pressure. Independent pressure display per station. Floor-standing design; controls above fixture prevent liquid short circuits
【Technical Parameters】:
1. 4 independent test stations. Each has a protective cover.
2. Control: Manual/button. Master pressure gauge for observation.
3. Pressure: Adjustable 20kPa/2psi (accuracy 0.1kPa).
4. Test pressure: 0-20kPa (2psi) (adjustable). Set points: 1.75kPa (±0.5 kPa), 3.5kPa (±0.5 kPa), 7kPa (±0.5 kPa), 14kPa, 20kPa (±0.5 kPa).
5. Micromanometer range: 0-0.1kPa.
6. Pressure resolution: 0.1kPa.
7. Timing accuracy: 0.1s.
8. Test medium: Synthetic blood (customer-provided).
9. Control: Manual/button.
10. Sample size: 75x75mm; Pressure area diameter: Φ57mm.
【Test Procedure】:
Secure sample on fixture. Spray 2ml/60ml synthetic blood (surface tension 0.042±0.002N/m) horizontally from 30.5cm distance using a 0.84mm ID needle at 16kPa/2psi pressure onto target area. Remove and visually inspect within 10s/60s.
