ISO5658-2 Construction Materials Testing Equipment / Configuration Tester

Product Specification

Lateral Flame Spread On Building Products In Vertical Configuration Testing Machine

Product Introduction:

Fire testing according to ISO 5658-2 evaluates a material's ability to withstand a fire spreading along its surface. The method is used to classify materials for trains and is referred to by EN 45545-2 - Railway applications - Requirements for fire behaviour of materials and Components.

Structural characteristics:

3.1. Cabinet made of stainless steel, beautiful and corrosion-resistant; easy to clean; main frame: consists of two independent parts of the burner frame and sample support frame. The two parts are bolted together and bolted for flexible mechanical adjustment.

3.2, the center height of the radiation board is 1200±100mm, and the angle between the radiation surface of the radiation board and the front surface is 15±3°.

3.3, radiation board size is 480mm × 280mm, composed of porous refractory tiles; radiation intensity of up to about 62kw / m2, the surface temperature of up to about 750 °C.

3.4. Burner: (200±10)mm long double-hole ceramic tube, internal diameter 6mm, each longitudinal hole diameter 6mm, equipped with propane and air flowmeter, adjustable flame height flame to meet standard (230±20) Mm high flame requirement.

3.5. Observed level indication: It is convenient for the user to observe the spread of the flame; it is made of stainless steel and is set in both horizontal and vertical directions with a spacing of 50 mm;

3.6, with sample mounting rails, made of stainless steel. Heat and corrosion resistance; sample installation for pull-type;

3.7. Observation Mirror: Equipped with an adjustable viewing angle (750mm x 120mm), the glass mirror and the sample can be used during the test to observe the flame propagation rate and can be automatically recorded through the foot switch.

3.8, sample clip size: length 808mm, width 250mm. Made of thick (3±0.2)mm stainless steel plate;

3.9, sample chimney, one, made of 0.5±0.05mm thick stainless steel sheet, equipped with gas and chimney metal compensation thermocouple.

3.10. Calibration plate: Long (795±1) mm, width mm, thick (25±2) mm noncombustible plate, drying density (950±100) kg/m3. There are 8 holes with a diameter of 25mm and a hole distance of 100mm ± 1mm;

3.11 Back plate and positioning piece: Non-combustible plate with back plate length of 800mm, width of 155mm, thickness (12.5±3)mm, drying density (950±100) kg/m3, positioning plate material same as back plate, width (25 ±2)mm.

Control system:

5.1, ignition source flame length 230 ± 20mm, propane flow 0.4L / s, air flow 1.0L / min;

5.2, radiation source gas flow: gas can be methane, natural gas, propane, flow ≥ 1.0L / s, flow control system in 0.5L / s ~ 1.5L / s error does not exceed 1%;

5.3, air flow ≥ 9.0L / s, flow control system in the 5L / s ~ 15L / s error does not exceed 1%, the air pipe contains a filter;

5.4, ​​imported brand pressure regulators and pressure gauges to accurately control the gas pressure;

5.5. Safety explosion-proof in all radiant panel combustion control systems, check valves, and solenoid valves to prevent gas backflow;

5.6, IMO program makes all calibrations, tests, test results printed (IMO, ISO) easier (optional);

5.7 Standard control cabinets, computer + Labview intelligent control system; the interface is more friendly and the test is more intelligent.
