We and our Bouen-dake are going to our next stage and we aim to get the authorization as a fireproof and/or non-combustible material which is designated by the Ministry of Land, Infrastructure, Transport and Tourism.
The test by the cone calorimeter method (prescribed by the Ministry of Land, Infrastructure, Transport and Tourism) have been conducted already several times by a private company to certify its fireproof specification standard. And the results were amazing that they can be categorized higher than "fireproof".
A material should clear the standard limit, less than 8MJ/㎡ as total calorific value during the combustion test, to get an authorization as "fireproof" and the test results with our Bouen-dake shows 1.84MJ/m2.
