Hello, one is that a certain treasure has a portable testing instrument, you can buy a personal test. There is also a local professional organization to conduct an actual door-to-door test, which is also a more accurate method.
There are no specific regulations on fireproof and anti-theft doors, to put it bluntly, the general fireproof and anti-theft doors are Class A fireproof and Class D anti-theft, because the definition of fire door front door thick steel plate, door frame, and anti-theft has been met for the plate requirements, but for this definition of the door anti-theft lock point to reach more than 6 must conflict with the definition of the fire door.
