Bac-ShieldT WS4 Lab Tests
Laboratory tested on various textiles and surfaces according to AATCC and ASTM industry standard tests.
Demonstrated effectiveness against odor-causing organisms, molds, and fungi.
Testing on specific textiles and surfaces is required to determine effectiveness against specific organisms on those substrates.
Mold / Fungi Test Results - 4/17/2006
The WS4 solution was applied on filter paper by dipping. The treated sample in wet state was tested directly. The solution content of treated sample is controlled in 110-120% (based on the dry weight of paper)
