2.5 Grade Flammability Fire Testing Labs DIN 4102 - 15 Building Materials Difficult
Description:
Buildingmaterials difficult flammability tester is my company according to the nationalstandard, which is used in the development and production of flame retardantperformance testing equipment, building materials applied to building materialsfire resistant performance test.Adopt computer control, high degree ofautomation.
Standards:
GB/T 8625 Test method of difficult-flammability for building materials
DIN 4102-15
Features:
Burning shaft furnace: the combustion chamber, burner, specimen support, air current stabilizer, and parts such as flue. Adopt computer control, furnace temperatureand pressure, high degree of automation.
The working principle of the instrument is as follows:
The start of theexperiment, the four has been the standard by the conditioning good specimen isvertically fixed on the bracket for test piece, composed of a vertical squareflue; the position is adjusted, to ensure that the sample relative distance of (250±2) mm.
For the formation of uniform flow in the combustion chamber in the lower part of the furnacebody, through the diameter of 200 pipeline at a constant rate and temperatureof input air shaft furnace, meet the provisions of the (10±1) m3/min air supply.
Adjusting the gasflow is(35±0.5) L/min; the air flow is(17.5±0.2)L/min, and then start the automatic ignitiondevice.
The testing time is 10min, when the average temperature of the flue gas visible combustion on thespecimen is definitely over or five thermocouples as measured by the maximumvalue of more than 200℃, flame can advance interrupt.
Technical parameters:
1. Power supply: 380V AC 50HZ using gas: methane (purity over 95%)
2. Flow meter: methane: 5 ~ 45L/min adjustable, air: 3 ~ 30L/min adjustable
precision level :2.5 grade
3. The specimen size: 190 x 1000 (mm), less than 80mm thickness of specimen four as a group.
4. Thermocouple:3.0mm diameter and 1.5mm armored thermocouple
5. The burner nozzle diameter: 3.5mm,dimensions: 200 x 200 (mm) from the bottom of 1000mm
6. The combustion furnace dimensions: length * width * height (unit: mm) 1020 x 1020 x3930
7. Internal dimensions: length * width * height (unit: mm) 800 x 800 x 2000
8. Weight:1 tons
