We consulted European laboratory and also studied Australian standard AS/ NZS 1716:2012. As a result, we and the laboratory agree that the indicators required by European standard EN 12941:1998+A1:2003+A20:2008 and Australian standard AS/NZS 1716:2012 are basically the same.As long as PAPR complies with European standard test, it also complies with Australian standard. Our SUN20( flip helmet)+PAPR system passed the European test and it passed the highest class/best class TH3P R SL of the European standard.
