First-class product
Qualified product
The test door is installed on the test device according to the use status. The door is in a closed state. After applying a force of 50N at the position perpendicular to the door handle, the door leaf should be able to open flexibly, as shown in Figure 2. Figure 2
5.2 Impact resistance
5.2.1 The test door is installed vertically on the test device using the on-site installation method. The door lock and latch are in a locked state. The impact point is at the handle of the door leaf (the test door is double-leaf open), as shown in Figure 3. a. The impact body is a spherical cloth bag with a diameter of about 350mm, which is filled with sand with a density of 1500kg/m2 (sand that can pass through a 2mm sieve hole) and weighs 30kg.
b. Sand bag lifting device, the distance from the center point of the sand bag to the rotating axis is about 3m. The sand bag is hoisted and falls at a distance of 200mm from the vertical direction. The impact force is applied to the door. When the sand bag rebounds, the sand bag is allowed to make a second impact c.
The impact test needs to be carried out three times.
