 ISO 11925 Combustibility Test Furnace For Building Materials

Usage range

The combustibility test furnace of the building materials controlled by the touch screen adopts the stainless steel box. It is an upgraded product with touch screen control, controllable automatic lifting and lowering of samples, and advance and backward adjustment of Bunsen lamp on the basis of the old jck-2 product. It is a high-configuration testing instrument for burning grade of building materials produced in strict accordance with the provisions of national standard gb8626-2007.The combustibility test furnace of building materials is used to measure the combustibility of building products in normal combustion environment by direct impact of small flame on vertically placed samples.The flammability test furnace of building materials is used to determine the combustion performance of grade B building materials (i.e. the determination of the combustion performance/flame retardant grade B of building materials) by means of Kleinbrenner principle of Germany and direct impact of small vertical flame.

 

Product Features

1. In line with ergonomic operation design, all the tests are completed by touch screen operation, with high degree of automation, which can store the previous test results and review the previous test data;

2. Servo motor driving model frame can be controlled and lifted automatically;

3. Bunsen lamp can be adjusted back and forth;

4.1.5mm stainless steel steel plate box;

5.2 double Angle observation and test of toughened Pyrex door, double (with lock) is convenient and practical

6. High pressure automatic ignition, durable combustion;

7. Ignition source can automatically tilt 45 degrees;

8. Flame height is adjusted by precision control valve;

9. The sample rack can be moved up and down and back and forth;

10. Equipped with two kinds of sample clamps.

11. Flame measuring scale;

12. High degree of automation, accurate experimental data and easy operation;

13. Box size: 835 x 400 x 815mm wide

14. Material: 1.5mm stainless steel

15. The bottom of the box is a flat natural vent, which is composed of 5cm*5cm square vents (1.5mm thick steel vents with a height of 50mm) to keep the air flowing smoothly

16. Meticulous workmanship, really no soldering process

17. Touched screen:

A. Size: 7 "effective display size 15.5cm long and 8.6cm wide;
