MU3052 VW-1 large combustion cabinet this large combustion cabinet is in strict accordance with UL1581 sect 1080.1 ~ 1080.14 standards, and has been the company's Guangzhou United States and China UL approved, full compliance with the VW-1 (Vertical-specimen) Flame Test combustion test standards. Affordable and a large number of wire and cable industry has been widely used. Parameters in detail as follows: The whole test in a test chamber volume of 4.32 cubic meters were sealed. Test Method: regulate the flame height, flame placed under the top specimen, burning 15 seconds, turns off for 15 seconds, repeat 5 times to check the specimen burned case, you can set the burning, extinguish time and repetition, and automatically operation. It applies to UL1581, UL13, UL444, UL1655 VW-1 and CSA of the FT-1, FT-2. The main reference standard: The test device satisfies UL1581-2001 Section 1060 (vertical burning and FT1 Test), 1080 (VW-1 flame test), 1090 (electrical burning test with a line level), 1100 (horizontal sample / FT2 burning test) requirements. Test Case (1) The test box with aluminum frame + electrolytic plate electrostatic spraying, has a beautiful appearance, rust and corrosion, etc. (2) at the top of the box with a powerful ventilation exhaust system, during the test is complete, and send simultaneously open air system, an exhaust gas is discharged to the outside can; during the test, the system is a closed state. (3) air box with the side door. When the test is complete, the ventilation system open to the air tank during the test, this closure to be closed. (4) The front housing is provided during the test can be sealed glass observation window for easy observation of the test case. (5) at the bottom of a glass observation window opened out into the hands and arms can operate the chamber hole, this hole with sealing gloves, impervious gloves operator uses to operate the combustion burner. (6) chamber volume size: the available space 2.4m (length) * 1m (width) * 1.8m (H), volume: 4.32m3. Dimensions 2.4m (length) * 1m (width) * 2.5m (H). Temperature Measurement System (1) thermal sensor (copper pipe and thermocouple) - conduit structure should be high conductivity copper. Length of 19.14 ± 0.02mm (2) K-type thermocouple, with 0.5mm diameter stainless steel tube make coat. (3) Digital Taiwan Taishi thermometer and British imports K-type thermocouple match. Reading is greater than 1000 ℃. (4) over the whole test system: movable, when it is placed in the test chamber temperature, temperature measurement. (5) equipped with electronic stopwatch: accurate to 0.1S (temperature check at the time of backup) test equipment and test fixture (1) The main fixture: test stand with a combustion burner (2) Test stand: made of stainless steel, sub-horizontal holder and freestanding vertical holder, namely FT1, FT2, VW-1 in three sizes. Perpendicular to the plane of the bracket with a blowtorch and a plane parallel to the viewing window for easy observation and operation. (3) The combustion burner (UL1581 designated blowtorch): To meet the requirements of ASTM D 5025-99, Standard power: vertical torch to 500W, horizontal torch to 225W, crater diameter: 0.90 ± 0.03mm, spout lamp length: 1.60 ± 0.05mm, from the air inlet orifice for the height 102mm; torch angle: 90 degrees, 20 degrees to the vertical (the longitudinal axis of the holding and generating the vertical angle of 20 ° in the vertical plane) (4) wedge frame: wedge increases, Ann burner It requires the installation of the wedge, and can be easily moved, and can be moved back to a predetermined position accurately. (5) can be measured with the horizontal and vertical burning inside, Waiyan ruler set. (6) with an accuracy of 1mm 500mm ruler one, to prepare for a test. Flow control system: (1) include: flowmeters, valves, back-pressure pipes (2) Flowmeter: Flow range 1000ml / min (3) combustion valve: 1, may be a gas flow regulator to 10 lb / cubic inches (4) back pressure tube: precision water column height to 5mm or less (5) back pressure of the liquid: provide the number of marked oil burning oil or green timing system and combustion system of the cumulative number of test equipment, combustion timing, holding burning Timing and three time timing retardant system, three timer functions as follows: Combustion timing: When burning torch reaches a predetermined position of the automatic recording Spitfire time (according to the provisions set: combustion 15S), test member By observing the set time, the time when the flame arrives instant, hands quickly rotating wedge frame, remove the burner. Support combustion timing: When the combustion timing arrives, the timer automatic timing; if a predetermined time (eg: Stop for fire 15S), this process, if the sample is burning the flame goes out, then again a second combustion, Repeat step combustion process. Retardant Timing: If, within the specified time step, does not go out, manually start another timer delay combustion, such as within the specified retardant time off, and then repeat the first step combustion test failed if within the specified time off, direct determination test failed. It can automatically record the number of combustion in order to avoid mistakes and be fitted with appropriate alarm buzzer (optional).
