LT-JJ32 Mattress and Sofa Flame Resistance Testing Machine
| 1 | Simulated match flame | a. Ignition source system: Two sets of stainless steel combustion tubes, each with an inner diameter of (8±0.1mm), an inner diameter of (6.5±0.1mm), and a length of (200±5mm). b. Hose: The length should be (2.5 to 3mm), the inner diameter should be (7±1mm), and it should be connected to the stainless steel combustion tube. c. Flow control system: It includes a flowmeter, a fine-tuning valve, a switch valve and a pressure regulating valve. To meet the requirement of a flow rate of (45±2) m1/min, the nominal output pressure provided by this system is 2.8kpa. e. Timing range: 0-999 seconds. It can respectively display and record the time of continued burning or smoldered burning, the time of fabric cracking, and the time of specimen extinguishing. f. The test distance of the igniter: adjustable from 20 to 80, with an automatic movement and withdrawal mechanism for the ignition. g. Flow measurement range: 10 to 100m ⁻ ¹ /min. |
| 2 | Smoldering cigarettes | a. Cigarette ignition source. b. The cigarettes are cylindrical cigarettes packaged with filters or without filters and interfaces, and meet the following requirements: Length: 60±5mm; Diameter: 8±0.5mm; Mass per unit length: (0.6±0.1) g/50mm. c. Cigarette burning time: (12±3) min/50mm. d. Among the same type of cigarettes, every 10 cigarettes form a group. Randomly select one cigarette from them and measure the burning time of the cigarette in the laboratory according to the following method: After the cigarette is pre-treated, take out one cigarette and make marks 5mm and 55mm away from the ignition end respectively. Insert a thin steel needle horizontally into the non-lit end of the cigarette, with the insertion length not exceeding 11mm. Light the ignition end and test and record the time it takes for the cigarette to burn between the two marks. |
| 3 | Laboratory | 2.5 meters in length, 2.2 meters in width, and 2.5 meters in height, including ventilation ducts. Made of stainless steel. |
| 4 | Observation window | One large tempered glass observation window, surrounded by SUS304 stainless steel. |
| 5 | Gas flow regulation | Adjust the test gas flow to 45±2mL/min. |
| 6 | Timing | Freely set from 0 to 99.99H/m/s |
| 7 | Control System | (1) The computer control system allows for the setting and recording of test time, test frequency, and flame delay time, etc., all in the computer. Possessing high intelligence and guidance The guided menu operation, with its simple and intuitive features, makes the test results more accurate. (2) Automatic ignition function (high-voltage electronic spark). (3) It adopts PLC mode and uses all high-quality components to ensure the system operates at high quality and high speed, and is advanced. Adopt imported The PLC+PID fully automatic control mode test process is the most advanced, safest, most reliable and most convenient control method nowadays Method. Realize automatic detection control and automatically complete the detection work. The friendly display interface makes the detection work faster and more accurate. The upper computer is designed with configuration software and can automatically generate temperature control curves and report outputs. Data collection and printing of test results. (4) Lenovo brand computer: Screen size: 18.5 inches, CPU model: AMD Snapdragon X2 190, CPU frequency: 2500MHz, memory capacity: 2GB DDR3, hard disk capacity: 250GB 7200 RPM, SATA2 graphics card chip: High-performance integrated graphics card shared memory capacity, optical drive type: DVD-ROM, operating system: WINDOWS XP, graphics card type: Integrated graphics card. (5) One printer. (6) One set of software, free upgrade for life. |
