The door with a vertical light chain is opened at the top of the door. The door is opened as far as possible by a slow downward force of 115N, but not more than 18u\. This test shall not be conducted frequently.
Note: Silicone can be used as a weight.
There are · The above door equipment · For each door, the test is carried out. For the door that is lifted, the force is applied to the farthest part of the chain. 20.12 To meet the requirements of 20.2, the gear guards installed at the motor and key components shall not be necessarily folded, unless the following conditions exist,
Suitable locking devices are installed to prevent the motor or fan from running when the guard is removed: 1- The guard is an integral part of the furnace tank. Compliance shall be determined by inspection or manual test. 21 Mechanical properties
G0170.1-1998 In addition to the following contents, the following contents shall apply:
GB 4706.34-2003/IFC 60335-2-42;1994 Note 13 For the device installed in the test boat, according to the height of the impact point, different impact energy levels are used. (Conference) 21.101 The design of the bracket should make it not fall off the support nest when 50% of the required time or depth is extended out. When 5U% of it is extended out, the bracket should not tilt. Compliance is determined by the following test. For a pancake-shaped tray or similar container with a rack area of 75%, the jade objects are evenly distributed, and the total mass is calculated as 43g/F. The pancake box is placed in the center of the bracket E. The bracket can be placed on the required mounting frame. The bracket is moved as far to the left of the support frame as possible. Stay for 1 minute and then take it out. Insert the bracket into the support frame and move it to the far right. Stay for 1 minute and then take it out. During the test, the frame should not fall off the support frame. Then, the bracket is tilted 5% out of the bracket and the test is repeated. Apply an additional force of 1 N vertically in the middle of the front edge of the bracket. During the test, the bracket is not tilted. 22. This chapter of G34703.1-15S8 shall be used except for the following contents: 22.7 This clause shall be replaced by the following: Gas rescue equipment and gas generators with a pressure higher than one person's atmospheric pressure (overpressure) shall be equipped with appropriate pressure relief devices to prevent exceeding the rated pressure. Other equipment shall work at the rated input power, and the positive pressure control shall not work. To determine whether it is qualified, during this test, the pressure relief device shall work to prevent the pressure in the device from exceeding the rated pressure by 29%. 22.101 Only water and oil deposits discharged from the exhaust 1 of the isolation compartment shall not accumulate to a depth sufficient to affect the creepage ionization and electrical room data.
Qualification shall be confirmed by the standard inspection.
22.102 Thermal interrupters for protection of electric circuits with heating elements and for protection of electric circuits which may cause a dangerous external start shall not be of the self-resetting, self-tripping type and shall be capable of being fully disconnected from the power supply. Ball-head type and capillary type thermal interrupters which operate during the tests of clause 19 shall be such that the rupture of the capillary does not affect compliance with the requirements of 19.13. Compliance shall be determined by inspection, manual test and rupture test. Note: Ensure that the rupture does not extend to the assembly seal. 22.103 Signal lamps, switches or buttons indicating danger, alarm or similar conditions shall only be red. Compliance shall be verified by inspection during the tests of clause 11. 22.104 The working pressure of steam recovery equipment and steam generators shall not exceed the locking pressure. Compliance shall be determined by inspection during the tests of clause 11. 22.105 The door of the pressure compartment of the pressure apparatus shall not be opened until the pressure inside it has dropped to near atmospheric pressure. After checking or testing manually, the quality is confirmed.
