Rhino® Guard (aka Aquastat®) Treated Substrate, Part No AF – XXXX (“XXXX” will designate the width of the paper and will vary)
Rhino Guard (aka Aquastat) treated material inhibits 99.9% of black mold growth for up to 3 months
The organism used during fungal inoculation is Aspergillus niger, which is commonly referred to as “black mold”. The assessment is performed per ASTM G21 – 15, Standard Practice for Determining Resistance of Synthetic Polymeric Materials to Fungi, with the following modifications: - Each sample is tested in quintuplicates with the spore suspension referenced above. - The fungus is directly pipetted on to the material, instead of sprayed, as called out in the standard. - The inoculated test specimens are incubated for 90 days, instead of the 28 days called out in the standard. The following calculations are made for fungal reduction: Percent Reduction = (CC - TC)/CC x 100 Log Reduction = log CC - log TC or alternatively log (CC/TC) Where: CC = Untreated Positive Control Sample viable organism count after test (use results of the control sample with the lowest count). TC = Treated Test Sample viable organism count after cycle (use results of the test sample with highest count).
