Levels of Barrier Protection for Isolation Gowns

ALL Personal Touch Isolation Gowns meet the test requirements set forth by AAMI PB70(from AAMI PB70:2003).

The chart below is set forth in the AAMI PB70 guidelines. The color-coding has been developed to differentiate each level and corresponds with the color-coded neck bindings.

ANSI/AAMI PB70 Barrier Performance

Test Method

Test Definition

Requirement

Level 1

Water Resistance: Impact Penetration AATCC 42

AATCC 42 Measures the resistance of fabrics to the liquid penetration of water by impact.

Level 2

Water Resistance: Impact Penetration AATCC 42

Water Resistance: Hydrostatic Pressure AATCC 127

AATCC 42 Measures the resistance of fabrics to the liquid penetration of water by impact.

AATCC 127 Measures the resistance of fabrics to the liquid penetration of water by impact under constant and increasing hydrostatic pressure.

Spray Impact Hydrostatic Pressure >/= 20 cm

Level 3

Water Resistance: Impact Penetration AATCC 42

Water Resistance: Hydrostatic Pressure AATCC 127

AATCC 42 Measures the resistance of fabrics to the liquid penetration of water by impact.

AATCC 127 Measures the resistance of fabrics to the liquid penetration of water by impact under constant and increasing hydrostatic pressure.

Spray Impact
Hydrostatic Pressure >/= 50 cm

Level 4

Viral Penetration ASTM F1671

ASTM F1671 Measures the resistance of fabrics to bloodborne pathogens using viral penetration at 2psi and ambient pressure.

Total Impervious

Our Isolation Gowns are color-coded by protection level for easy identification.

To help easily identify the protection levels for Isolation Gowns, we have color-coded the neck bands to correspond to AAMI classification levels.

Level 1

Level 2
