Audited Supplier BS476.7 Electrical Building Components Surface Flame Spread Materials Test/Testing Machine
1. Product Description
It is designed according to the requirements of BS476.7.To carry on the building components surface flame spread tests.
Equipment consists of a vertically mounted radiant heat plate and sample holder. Heat source of the radiating plate is provided by the combustible gas and the air combustion.
2. Standards
BS476.7
3. Technical Parameters
| Power supply | AC220V±10% 50Hz or 60Hz |
| Radiant plate (main fire source) | Size: 850mm *850mm, porous burner base, It should be designed to ensure that the mixture air can be fuller combustion, during the test process, the heat source plate should without any fire burning phenomenon. |
| Radiating plate | Surrounded by the refractory concrete, the plate around and the gap is fill with the Non-combustible insulation material. |
| The center of the radiation plate | 1250 ± 100 mm higher than the floor, plated it on the rigid metal bracket |
| Auxiliary burner (secondary fire source) | The inner diameter is 3 mm, an outer diameter is 6.4 mm |
| Position | Place it away from the test sample surface (28 ±2) mm position, and higher than the test sample install bracket (6 ± 2) mm position, and the install rank vertical edge(15 ± 5) mm position |
| Sample Mounting plate | The mounting plate and the test sample overlapping 20 ± 5 mm at the top and the bottom edge, keep the surrounding of the test sample cooling, and use the spring loaded fixture to clamp the test sample |
| Cooling water temperature | Should can be regulated, should guarantee the maximum temperature can not exceed 35° during the test |
| Switching and systems | Flame and gas related protection (including sub-fire, gas, gas stop control button) |
| Heat flux measurement system | Imported water-cooled heat flux sensor |
| Test chamber | Composed by the chassis, radiant heat panels, heat source supply systems (including gas, air and mixing device), the gas flow control system (pressure and flow control), the test sample mounting plate, the water cooling system (including waterways, water pumps and water cooling devices, etc.) and test calibration plate |
| Test control system | Consists of pressure sampling system, temperature sampling control system, data acquisition systems, computer systems, coupled with well-designed test and sampling circuit |
| Safety guard | When the system detects the security problem signal, can real-time feedback system to adopt urgent shut down safety measures |
| The electrical signal | Generated by the thermocouple can through the temperature transmitter or may be directly sent to the recorder or computer during the test, the average temperature, single point temperature should be displayed at all times |
| Test test control system component | consists of temperature sampling control system, data acquisition systems, computer systems, coupled with well-designed test and sampling circuit |
| The system function | The system can display the test data, output and query wq curve; also it can key in the number of the test samples, the test date, to provide the search functions |
| The system automatically to save the temperature curve and data stored in the database system based on the the test sample series number | |
| The tester is with the electrical safety alarm function, over temperature protection alarm function, and with the test sample explosion shock shields | |
| Computer control system | including brand computers and 19-inch LCD monitor, laser printer and software systems |
| The system does not make the final qualified judge for the test sample | |
| Exhaust system | with the hood (plenum), smoke exhaust flue, adjustable speed wind exhaust fan, 10 meters pipe (optional) |
| Test sample size | 1m×1m (For other specifications, the price is need to another negotiable) |
Experimental site:
| Area | AboutL2000mm×W1800mm×H2000mm |
| Control bench | About L700mm×W600mm×H1700mm |
| Should with the external ventilation space | |
| Gas consumption | 50-60kg / h (it should be matching with the customer self, should ensure the gas supply and heat value) |
