Infectious Agent Barrier Protective Clothing Testing
What is Infectious Agent Barrier Clothing Testing?
Infectious pathogens responsible for diseases vary widely in type, size, shape, growth conditions, and survival environments. Given this complexity, thoroughly verifying the protective performance of barrier clothing is an essential safety measure for workers.
In medical facilities (e.g., medical gowns and isolation suits), quarantine operations, and hygiene management sectors where exposure to contagious pathogens is a risk, selecting and using appropriate personal protective equipment that matches the level and type of exposure is crucial. From high-risk medical environments to general infection prevention, various protective clothing materials and products undergo comprehensive testing and evaluation to systematically confirm their required biological safety and barrier effectiveness.
Test Items
Biological Safety Evaluation of Infectious Disease Protective Clothing
| Test Item | Test Standards | Description |
|---|---|---|
| Resistance to Penetration by Blood and Body Fluid | KS K ISO 16603 ISO 16603 ASTM F1670/F1670M-17a |
Assesses visual penetration of test specimens under defined pressure using synthetic blood that simulates the surface tension, viscosity, and pH of blood and certain bodily fluids. |
| Resistance to Penetration by Blood-borne Pathogens | KS K ISO 16604 ISO 16604 ASTM F1671/F1671M-13 |
Evaluates the presence of virus penetration under pressure using bacteriophage Phi-X174, which specifically infects E. coli, to model viral contamination not visually detectable. |
| Resistance to Wet Bacterial Penetration | KS K ISO 22610 ISO 22610 |
Measures time-dependent penetration resistance of bacteria carried by liquid, applying friction, pressure, and moisture effects. |
| Resistance to Dry Microbial Penetration | KS K ISO 22612 ISO 22612 |
Tests resistance of materials to dry particles including bacterial spores (such as talc) subjected to vibration at 20,800 cycles per minute. |
