## Key takeaways

- EN 14126 is the European standard that proves protective clothing can block bacteria, viruses, and other microorganisms, not just liquid chemicals.
- To carry the "B" suffix (e.g., Type 4-B), a fabric must pass tests including ISO 16604 (blood-borne viral barrier), ISO 22610 (wet bacteria), ISO 22611 (bio-aerosols), and ISO 22612 (contaminated dust).
- Kae Hwa's InduBarrier™ and MediShield™ series are engineered to achieve Class 6, the highest class, across these EN 14126 tests.

## Frequently asked questions

### What does EN 14126 certification mean for biological protective clothing?

EN 14126 is the European standard for protective clothing against infective agents, and it is the proof a fabric can block bacteria, viruses, and other microorganisms for medical and industrial safety buyers. Earning the B suffix, as in Type 4-B, requires passing tests such as ISO 16604 for blood-borne viral barrier, ISO 22610 for wet bacteria penetration, ISO 22611 for bio-aerosols, and ISO 22612 for contaminated dust, so a certified fabric is verified against liquid, aerosol, and dust-borne biological hazards, not just liquid chemicals.

### What's the difference between a "Type 4" rating and a "Type 4-B" rating?

A "Type 4" rating only certifies a garment as spray-tight against liquid chemicals. The "B" suffix (Type 4-B) means it has additionally passed the EN 14126 biological hazard tests, so it is certified to protect against bacteria, viruses, and other microorganisms as well.
