2.5 Meet the requirements of RTCA/DO-160G "Environmental Conditions and Test Procedures for Airborne Equipment User Guide Chapter 26" G26.6.2, G26.6.3, G26.6.4.
3. Main performance parameters:
3.1 Test types: divided into four categories: vertical combustion test, horizontal combustion test, 45° combustion test; 60° combustion test.
3.2 Instrument composition: consists of three parts, combustion box, control part and test device;
3.3 Combustion box:
3.3.1 The vertical combustion test, horizontal combustion test, and 45° combustion test share the same box; the 60° combustion test is an independent combustion box.
3.3.2 The front of the box is equipped with a tempered glass observation window sealed during the test, which is convenient for observing the test.
3.4 Combustion torch:
3.4.1 A Bunsen burner is used, the inner diameter of the flame outlet: Ф9.5±0.1mm, the steam outlet: Ф0.9±0.03mm, and the height of the nozzle from the air inlet is 100±10mm. Two in total
3.4.2 Torch angle: 0°, 45°, 60°, 90° adjustable;
3.4.3 Flame height: 20mm~100mm can be adjusted arbitrarily. Adjust the flame height according to different test types.
3.5 Timer: burning time, flame burning time, smoldering time, and flame burning time of drops. Timing accuracy 0.1S, timing range: 0~99.99s/m/h can be set;
3.6 Length gauge: resolution 1.0mm;
3.7 Temperature measurement system:
3.7.1 Thermocouple: K-type thermocouple with a diameter of 1.2~1.5mm;
3.7.2 Temperature meter: It is a hand-held thermometer with a range of 0~1000°C and a resolution ≧1°C;
3.7.3 Equipped with electronic stopwatch: accurate to 0.1S (standby during temperature measurement verification);
3.8 Sample fixture: made of stainless steel, divided into horizontal test rack, vertical test rack, 45° test rack, 60° test rack;
3.9 Gas: use methane with a concentration of not less than 99%;
3.10 Power supply: AC220V, 500W;
3.11 Use space: length 1600mm, width 650mm, height 850mm;
3.12 Emission of smoke and dust: not including a fume hood, it is an optional accessory.
