ISO11925-2 Building Material Flammability Tester PLC Control
1. Introduction
The building material flammability tester is designed according to GB/T8626-2007 and ISO11925-2:2020 standards. In a normal combustion environment to assess the flammability of building products by direct impingement with a small flame on a vertically placed specimen.
The device is controlled by PLC and touch screen, the combustion chamber is made of stainless steel sheet with a heat-resistant glazed door, configure with gas burner and adjustment valve, specimen holder and etc., all the sizes are strictly manufactured as per the standard requirement.
2. Parameters
| Control units | PLC+7 inch LCD touch screen |
| Combustion chamber | 1). Completed designed according to ISO11925-2 figure 1 2). Material: made of stainless steel sheet with thickness 1.5mm 3). the heat-resistance glazed doors are installed on front and right-side panels 4). Outer dimension: W1000mm*D400mm*H810mm 5). Ventilation of the enclosure shall be free through the square box section base in the bottom of the chamber, the air vents consist of 5cm*5cm open squares (made of 1.5mm thickness stainless steel and 50cm in height) to keep the air flowing smoothly. |
| Ignition source | 1). The burner is completed designed according to ISO11925-2 figure 2 2). The burner shall be mounted onto a horizontal plate so that it moves smoothly forwards and backwards in a horizontal plate along the centreline of the combustion chamber 3). The burner can be used vertically or be tilted at 45° with respect to the vertical axis |
| Fuel | Commercial propane of 95% minimum purity, the gas pressure shall be between 10kPa and 50kPa (prepare by user) |
| Specimen holder | 1). The specimen holder is completed designed according to ISO11925-2 figure 3, and vertical installed as per figure 4 2). consisted by 2 stainless steel U-sharped frames, the frame has a thickness of 5±1mm,the two halves of the specimen holder shall be held together by screws or clamps to prevent the specimen warping. |
| Flame height gauge | Completed designed according ISO11925-2 figure 8 |
| Burner positioner | Completed designed according ISO11925-2 figure 9, edge flame impingement*1, surface flame impingement*1 |
| ignition | High pressure automatic ignition, durable combustion |
| Test flame height | 20±1mm (the flame height is adjusted by flowmeter, and measured by flame height gauge) |
| Flame application time | 0-999.9s (presettable) |
| Test time | 0-999.9s (presettable) |
| Anemometer | hot wire, with an accuracy of ±0.1m/s, for measuring the airflow velocity in the upper outlet of the combustion chamber |
| Input power supply | AC 220V/50Hz |
| Working condition | 15℃~35℃ (ambient temperature), ≤85% (R.H.) |
