UL/ULC tested and certified? Has any accredited testing agency applied their approval mark to these?
I would say no. This is from their website.....

IS ELEMENT CERTIFIED?
Originating in Italy, Element has been certified for sale in Europe by CE and TUV. Institutionally it has been tested and certified for use by multiple international military and police groups who have adopted it for active use.
In North America, Underwriters Laboratories (UL) is responsible for the certification of fire extinguishers. UL does their testing to a standard that contains a form (physical shape) component followed by a performance component. Because Element's form does not fit inside of UL's guidelines of what a traditional fire extinguisher looks like (i.e. compressed gas cylinder with a hose and measurement gauge) it is immediately passed over for performance testing. At present UL is being campaigned to update its standards to recognize the different form offered by Element and allow it an opportunity to be tested and certified.
Until the standards are updated Element cannot be used to
substitute extinguishers in regulated environments that require a UL (or UL endorsed) certification. Element can however be freely used as an
supplement to the extinguishers used where regulation exists.
There are no restrictions in non-regulated environments (car, home, personal garage, etc.) allowing Element to be used freely.
