Fire test method for doors and roller blinds
Note. All personnel who organize and participate in this test should be aware that fire tests may be hazardous. Because there is a fire test
May produce toxic and/or harmful fumes and fumes; in addition, during the installation of the test piece, the test process and the cleaning of the residue after the test,
Mechanical hazards and operational hazards may occur. Therefore, all potential hazards and health hazards should be assessed and safety precautions made.
Report. Perform the necessary training for relevant personnel to ensure that laboratory staff operate in accordance with safety procedures.
1 range
This standard specifies the fire test method for doors and roller blind assemblies installed at the opening of vertical partition members. Such as.
---Hinged door, pivot door;
---Horizontal sliding door, vertical sliding door, including linked sliding door and sectional door;
---Shutter doors;
---Other sliding and folding doors;
--- flap door;
--- A board that can move in the wall.
The test methods specified in this standard can also be used to determine the fire resistance of non-load-bearing horizontal doors and roller blinds by analogy, given in Chapter 13
The direct application range does not apply to horizontal doors.
This standard does not include mechanical adaptability requirements, such as vibration tests or endurance tests, which are included in the relevant product standards.
