Hi Jarv55, think we've got the ISO cert already as per the RNS dated 11 Nov:
Tests showed that the masks, which are Type IIR - meaning they offer the highest level of protection and have a filtration efficiency of 99.98% - were highly effective, at killing more than 90% of the influenza and coronavirus over seven hours, and have been certified to ISO 18184 standards.
