Description: The flammability test furnace for building materials is to directly impact a vertically placed sample with a small flame in a normal combustion environment to determine the flammability of building products. The flammability test furnace for building materials uses the German Kleinbrenner (Kleinbrenner) principle to measure the combustion performance of Class B building materials under the direct impact of a small flame in the vertical direction (that is, for the combustion performance of building materials / flame retardant grade B level judgment). Standards compliant: ISO11925-2:2002 E "Test method for flammability of building materials" GB/T8626-2007 "Test method for flammability of building materials" DIN53483 DIN 4102-1 Features: 1. Ergonomic operation design; 2. 1.5mm thick brushed stainless steel plate box; 3.2 double-angle observation test of tempered heat-resistant glass doors, double (with lock) is convenient and practical (as shown in Figure 3) 4. Independently modify the hand-held igniter for durable combustion; 5. The ignition source can be vertical or 45 degrees; 6. The flame height is adjusted by the precision regulating valve; 7. The sample holder can be moved up and down and back and forth; 8. Equipped with two sample holders. 9. Flame measuring ruler; 10. High degree of automation, accurate experimental data and easy operation; 11. Features of JCK-2 type building materials flammability test furnace combustion box: 12. Box size: W835*D400*H815mm 13. The bottom of the box is a horizontal natural vent, and the vent consists of a 5cm*5cm square vent (a real 1.5mm stainless steel thick steel plate vent, 50mm high). Keep the airflow smooth through . Specifications: 1. Ambient temperature: 15ºC~25ºC; 2. Relative humidity: ≤85%; 3. Supply voltage and power: 220V 50HZ 100W; 4. Gas source: liquefied petroleum gas; 5. Bunsen burner applies flame to the pattern for 15s 6. Single chip control, digital display. 7. The aperture of the burner is Φ0.17mm, the flame length of the Bunsen burner is 20mm±2mm, and the burner can be tilted 45°. 8. Apply flame to the sample (1s-99s)±0.5s, which can be adjusted arbitrarily, with an accuracy of ±0.2s. 9. Combustible gas source: propane with a purity of more than 95%.
