AAMI Level – Isolation Gown
What is AAMI Standard?
The AAMI Standard (Advancement of Medical Instrumentation “AAMI” PB70 standard) classifies surgical gowns into four
categories based on their liquid barrier performance using a combination of industry standard tests.
AAMI Guidelines: A Reliable Benchmark for Protection Protective apparel must meet minimum performance standards for
strength, barrier protection and fluid resistance to ensure the safety of healthcare workers and patients. AAMI guidelines
are a widely accepted system of classification for protective apparel and drapes based on liquid barrier performance.
To fully qualify as an AAMI rated product, the gowns must be tested and each gown must be labeled to indicate the level
of protection provided.
This standard provides stratification of apparel protection based on liquid barrier performance and a benchmark to help
determine the most appropriate protection for a particular task or clinical situation.
