What is a fire door?
A fire door is a door that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. It can only be called a fire door if it is tested by a laboratory designated by the Ministry of Fire and the Ministry of Economic Affairs according to the fire resistance test method of relevant national standards and obtains the corresponding verification registration certificate and authorized logo.
Fire doors are classified according to fire resistance performance:
? Insulated fire doors (Class A): Fire resistance insulation and fire resistance integrity meet the corresponding time requirements at the same time, such as fire resistance insulation ¡Ý 0.50h, fire resistance integrity ¡Ý 0.50h is A0.50 (Class C); fire resistance insulation ¡Ý 1.00h, fire resistance integrity ¡Ý 1.00h is A1.00 (Class B); fire resistance insulation ¡Ý 1.50h, fire resistance integrity ¡Ý 1.50h is A1.50 (Class A), etc.
?Partially insulated fire doors (Class B): Fire insulation ¡Ý 0.50h, fire integrity meets the corresponding time requirements, such as fire integrity ¡Ý 1.00h is B1.00; fire integrity ¡Ý 1.50h is B1.50, etc.
?Non-insulated fire doors (Class C): Only meet the fire integrity requirements, such as fire integrity ¡Ý 1.00h is C1.00; fire integrity ¡Ý 1.50h is C1.50, etc.
Fire door classification:
Wooden fire doors, steel fire doors, steel-wood fire doors, other materials fire doors.
AS 1530.4 Fire Test Introduction:
1. Standard Name:
AS/NZS 1530.4: Methods for fire tests on building materials, components and structures - Fire-resistance test of elements of construction
2. Judgment Basis:
? Loss of integrity: When the cotton pad is ignited or the backfire surface burns for more than 10 seconds, the specimen is considered to have lost its integrity;
During the test, a 6mm diameter probe can pass through the crack into the furnace and the probe can be no less than 150mm along the length of the crack;
When a 25mm diameter probe can pass through the cra |
