The Resistance to Ignition of The Spring Mattress and the Sofa Upholstered Furniture Testing Equipment

Scope:

The standard GB17927.1~2-2011 testing equipment is suitable for soft spring mattresses and sofas used in hotels and families.

Standard:

GB17927.1~2-2011

Technical parameters:

1. Simulated match flame
a. Ignition source system: stainless steel combustion tube with external diameter of (8 ±0.1) mm, inner diameter of (6.5 ±0.1) mm, and length of (200 ±5) mm, to prepare two sets.
b. Hose: the length should be (2.5) m, and the inner diameter should be (7 ±1) mm, connected to the stainless steel combustion tube.
c. Flow control system: includes a Flowmeter, micro-valve, on-off valve and pressure regulator.
d. The flow rate is (45 ±2) mL/min, and the nominal output pressure of the system is 2.8kPa.
e. Timing range: 0 / 999s, can show and record the time of continuous burning or smoldering, the time of fabric cracking, the time of specimen quenching respectively.
f. Ignition test distance: 20: 80 adjustable, with automatic movement and evacuation of ignition mechanism.
g. Flow measurement range: 10-100 mL / min.

2. Smoldering cigarettes

a. Cigarettes ignite the source of fire.
b. Cigarettes are cylindrical cigarettes with filters, or without filters and interfaces, and meet the following requirements: length: 60 ±5 mm; diameter: 8 ±0.5 mm; unit length: (0.6 ±0.1) g / v 50 mm.
c. Cigarette burnout time: (12 ±3) min/50mm.
d. In the same type of cigarette, every 10 cigarettes were taken from one cigarette, and the burn-up time of the cigarette was measured in the laboratory according to the following method: 7.1 (temperature (23.0 ±2.0) ºC, relative humidity (50.0 ±5.0)%), After the sample and cigarette were pretreated for at least 16 hours, one cigarette was taken out and marked at 5mm and 55mm at the ignition end of the cigarette. The non-igniter end of incense smoke was inserted horizontally into a fine steel needle, and the insertion length was not more than 11 mm. Ignite (light a cigarette until incense) as specified in 8.2 In the process of ignition, the consumption of cigarettes should be between 5mm~8mm), and the time taken to burn the incense between the two marks was recorded by the test.
3. Laboratory: 2.5 m long, 2.2 m wide, 2.5 m high, with ventilation pipes. Made of stainless steel.
4. Observation window: a large observation window of toughened glass, surrounded by SUS304 stainless steel.
5. Gas flow regulation: regulate the flow rate of the test gas to (45-2) mL/ min.
6. Timing:0-99.99 h/ m/ s.

7. Control system:
1) computer control system, test time, test times, delay time, etc., can be set and recorded in the computer. With high intelligence, guide menu operation, simple and intuitive characteristics, make the test results more accurate.
2) automatic ignition function (for high voltage electronic ignition).
3) adopt PLC mode, all adopt high quality device, ensure the system high quality, high speed operation, have advanced.
The test process of imported PLC PID automatic control is the most advanced, safest, most reliable and convenient control method. Automatic detection control, automatic completion of testing work, friendly display interface, so that the detection work faster, more accurate. The upper computer adopts configuration software design, can automatically generate temperature control curve and report output data acquisition and print test results.
4) one computer and one printer each.
5) A set of software, life-long free upgrade.
