ANSI\/AAMI PB70:2012<\/strong> – Liquid barrier performance & classification of protective apparel & drapes intended for use in health care facilities.<\/p>\n

The ANSI\/AAMI PB 70:2012<\/strong><\/em> standard establishes minimum barrier performance requirements, a classification system and associated labelling requirements for protective apparel, surgical drapes, and drape accessories intended for use in health care facilities.<\/p>\n

The classification system places protective apparel, either disposable or re-usable into levels of barrier performance. The four levels essentially measure the level of resistance to fluid penetration.<\/p>\n

The levels measure increasingly higher levels of protection with Level 1 offering protection against liquids that may splash onto the user up to Level 4 offering resistance to liquid and viral penetration.<\/p>\n

Level 1 \u2013 Minimal protection against liquid splashing<\/strong><\/p>\n

Level 2 \u2013 Low level of protection toward liquid impact and liquid penetration<\/strong><\/p>\n

Level 3 \u2013 Moderate level of protection toward liquid impact and liquid penetration<\/strong><\/p>\n

Level 4 \u2013 High level of protection toward liquid and viral penetration
<\/strong><\/p>\n


AWTA Product Testing has the capability to test up to and including Level 3.<\/p>\n

<\/em>There are two tests required for level classification namely:<\/p>\n

AATCC 42 \u2013 Water Resistance: Impact Penetration Test<\/p>\n

This test measures the resistance to water penetration by impact or splashing.<\/p>\n

AATCC 127 \u2013 Water Resistance: Hydrostatic Pressure Test<\/p>\n

This test measures the resistance to water penetration under hydrostatic pressure or under a water column.<\/p>\n

The table below shows performance requirements for level classification.<\/p>\n
