ISO11925 Flammability Testing Furnace Equipment for Evaluating Building Materials' Fire Retardant Properties
Introduction:
Building Material Ignitability Test Apparatus is designed and developed according to GB/T8626 and ISO11925. It is suitable for measuring the flammability of building products by directly impacting a vertically placed sample with a small flame without external radiation. It is also suitable for the combustion test of the latest version of GB8624-2014 fire rating of building materials, and can test B1 level, B2 level, etc.
Standards:
EN ISO 11925-2---Reaction to fire tests -- Ignitability of products subjected to direct impingement of flame -- Part 2: Single-flame source test
DIN 53438---Testing of combustible materials
DIN4102-1---Fire behaviour of building materials and elements Part 1: Classification of building materials Requirements and testing
Features:
1. With ergonomic operation design, all tests are completed through touch screen operation, with high degree of automation. Results of previous tests can be stored and data of previous tests can be retrieved;
2. Servo motor drives the design frame to control automatic lifting;
3. Bunsen lamp can adjust advance and retreat;
4.1.5mm stainless steel plate housing;
5.2 toughened glass doors with double Angle observation and test, double (with lock) convenient and practical
6. High pressure automatic ignition, durable combustion;
7. Ignition source can automatically tilt 45 degrees;
8. The flame height is regulated by the precision regulating valve;
9. The sample rack can be moved up and down and forward and backward;
10. Equipped with two sample clamps.
11. Flame measuring scale;
12. High degree of automation, accurate and easy to operate experimental data;
13. Box size: width 835× depth 400× height 815mm
14. Material: 1.5mm stainless steel
15. The bottom of the box is a flat natural air vent, which is composed of a 5cm*5cm square air vent (a real 1.5mm thick steel plate air vent, with a height of 50mm) to keep the airflow flowing smoothly
16. Meticulous workmanship, really no welding process
17. Touch the display screen:
A. Size: 7 inches effective display size: 15.5cm long and 8.6cm wide;
B. Resolution: 800*480
C. Communication interface RS232, 3.3v CMOS or TTL, serial mode
D. Storage capacity :1G
E. Adopt pure hardware FPGA drive display, "zero" start time, power on and run
F. Adopt M3+FPGA architecture, M3 is responsible for instruction parsing, FPGA focuses on TFT display, speed and reliability are ahead of similar schemes
G. The main controller adopts low-energy processors and automatically enters the energy-saving mode
Main technical parameters
1. Ambient temperature: 15℃ ~ 25℃;
2. Relative humidity: ≤ 85%;
3. Supply voltage and power: 220V 50HZ 100W;
4. Gas source: commercial propane with a purity of not less than 95%, and LPG can be used in ordinary test instead (gas source with transportation safety needs to be provided by users);
5. Apply Bunsen lamp to the pattern for 15s
6. Single chip microcomputer control, digital display.
7. Burn aperture is Φ 0.17 mm, Bunsen flame length of 20 mm + / - 2 mm, burner can tilt 45 °.
8. Apply flame (1s-99s)±0.5s to the sample, which can be adjusted at will with an accuracy of ±0.2s.
9. Combustible gas source: propane with purity over 95%.
Control System:
1. Programmable Logic Controller (PLC) Control.
2. Automatic timing, automatic detection of the flame, automatic ignition, ignition abnormal protection.
3. LCD touch screen display.
4. Real-time monitoring of experimental data, queries six samples of experimental data, query alarm content.
