Wire and cable bundle vertical burning tester
According to IEC 60332-3-10, IEC 60332-3 standard wire and cable bunched combustion test requirements and other relevant provisions of the design of the equipment. Provides a type approval test method for evaluating the ability of bundled cables to suppress flame spread under specified conditions.
I. Equipment features and structure:
Wire and cable into a bundle of combustion testing machine is divided into the test box part, the control box part, the rain curtain dust and activated carbon purification device in four parts, the control box and the test box is split, easy to operate, the test process produces exhaust can be initially purified to prevent pollution of the environment.
1, the test box body according to standard requirements design, height 4000, width 1000, thickness 2000, and in front of the test i ]and observation window, easy to observe the test specimen test.
2、Configuration of test steel ladder, standard 500 wide, and according to the requirements of the test specimen configuration of independent burners.
3、Configured to meet the requirements of the air extraction system and air intake, air extraction can be adjusted to meet the standard requirements of the air flow.
4、Placement of temperature monitoring thermocouple, can display the temperature inside the test chamber.
5, supporting an explosion-proof lighting; .
6、Supporting rain curtain dust removal and activated carbon purification device, in addition to prevent the test exhaust gas pollution of the environment.
II. Technical parameters:
1, Power supply: AC220V ± 10% / 50Hz.
2, The test box width (1000 ± 100), depth. (2000 ± 100), high. (4000±100), the bottom of the box should be higher than the ground; the periphery of the test box should be sealed, the bottom of the box in front of the wall (150 ± 10) mm at the opening of a (800 ± 20) mm x (400 ± 10) mm air inlet; in the back of the top of the test box there is a (300 ± 30) mm x (1 000 ± 100) mm air outlet.
3, The inner wall is made of S304 stainless steel and the outer layer is made of 50mm flame-retardant and heat-insulating colour steel.
4, The test box and the device in the metal materials are used 304 stainless steel and other corrosion-resistant materials.
5, The back and sides of the test box should be wrapped with heat transfer coefficient of about 0.7 W / (m2.K) of thermal insulation materials.
6, Equipped with standard requirements of the steel ladder 1 set of two pairs, 800x 3500mm, 500x 3500mm each pair.
7, Equipped with air flow detection device and air flow adjustment device.
8, Thermocouple is installed inside the test box.
