- Determination of resistance to penetration by a series of short liquid jet to a real human subject.
- The jet targets to the weak points of clothing, such as zipper, crotch, fabric joints.
- Test subject is standing on a rotating platform and doing specific movements for 360 degrees test.

- This test is performed by real people in a dusty chamber to determine the barrier efficiency against aerosols of dry, fine dusts.
- The test method require doing a series of specific movements , include kneel , squat, and walk, etc. on a treadmill before and during the test.
