Product introduction:

How to determine the opening direction of the fire door?

As an important part of fire equipment. Fire doors are used to prevent the fire area from spreading to another area. Can meet the characteristics of fire stability, heat insulation requirements, mainly used in fire rooms, evacuation stairwells, shafts and so on

Fire doors are classified into class A, B and C according to the fire rating. According to the material can be divided into wood fire doors, steel fire doors and steel wood fire doors.

According to the open state, it is divided into normally closed fire door and normally open fire door.

In the event of a fire, if there are too many people to escape, it is easy to cause crowding. When passing through the fire door, the fire door that opens along the evacuation path opens easily. Even if it is crowded, it can be pushed away. If opened in the opposite direction will bring inconvenience, evacuation time is long, need to spend more energy, waste of time.

Fire doors in high-rise civil buildings should be side doors that open in the direction of evacuation and, after closing, should be able to be manually opened from either side. At the same time, fire doors for evacuation sidewalks, stairwells and front rooms should have automatic closing functions. Double-leaf and multi-leaf fire doors shall also have the function of sequential closing.

Gb50016-2006 "Building fire Design code" provides that the evacuation door of civil buildings and factories should be opened in the direction of evacuation. Except for the production room with numbers A and B, there is no restriction on the direction of opening when the number of people does not exceed 60 and the average number of evacuees per door does not exceed 30.

Normally, the fire door opens in the direction of evacuation, upright on the outside of the door, facing the hinge, which opens right to the outside and left to the outside.

How does third-party authentication work?

Independent institutions conduct tests to determine the performance of the product, and formal evidence of testing comes from the notified laboratory. One of the main guarantees is factory product audit sampling. The test evidence only relates to the performance of the product on the day of the test, and the product provided by the manufacturer may not reflect the previous test. However, independent sampling from the factory's production lines for testing and checking quality control measures in the production process can provide better assurance. Certification tests cover a variety of different parameters, and once a fire door passes the required tests, it is listed on a separate public registry by the certification body. Annual control and test reviews are then required to ensure that the product continues to meet standards.
