ISO 5659 Flammability Tester Computer Control Plastic Combustion Smoke Density

Product Specification

ISO 5659 Plastic Smoke Density Tester Flammability Tester Computer Control
 
1. Instrument use
The plastic combustion smoke density tester is a new type of test equipment for measuring smoke density developed according to the technical conditions specified in the national standard GB/8323.2-2008. This standard is applicable to the determination of the optical density generated by the combustion of plastics, and the maximum optical density is used as the test result to evaluate the smoke performance of plastics under specified conditions.
It complies with the test standards of GB8323.2-2008 "Plastics-Smoke Generation-Part 2: Single Chamber Method for Determining Smoke Density" and ISO5659.2-2006 "Plastics-Smoke Generation-Part 2: Single Chamber Method for Determining Optical Density". The whole instrument consists of a closed test chamber, a photometer measurement system, a radiation cone, a combustion system, an igniter, a test chamber, a bracket, a thermometer table and a smoke density test software; the circuit is developed using a single-chip microcomputer, with high technical content and stable performance. This instrument is suitable for all plastics, and can also be used to evaluate other materials (such as rubber, textile coverings, coatings, wood and other materials), and is widely used in plastics industry, solid material industry production plants and scientific research and testing units.
 
2. Test chamber
The front door is installed with a window and a movable opaque screen that can block the window, the bottom of the square box is installed with blasting aluminum foil to prevent overpressure, and the top is installed with an internal pressure regulating device of the box.

2. Receiving device: for silicon photocell, transmittance 0% for no light through, transmittance 100% light without blocking completely through.
 
3. Radiation cone
1. radiation cone: by the rated power of 2600W heating element, can provide 10KW/m2~50KW/m2 in the center of the sample surface radiation intensity.
2. radiation cone heater: by an independent power supply transformer power 3000W, single-phase isolation transformer temperature controller, silicon controlled.
3. heat flow meter: range of 50 kW /m2, receiving radiation area diameter of 10mm flat area, using water cooling.
4. igniter: igniter nozzle is made of Φ4.0mm aperture copper tube, flame length, horizontal measurement is 30mm.
Combustion system: composed of pressure regulator valve, filter, regulating valve flowmeter and burner.
1. Gas is propane with a purity of more than 95%
2. burner: composed of igniter and nozzle, nozzle is 10mm higher than the horizontal position of the upper surface of the sample, and placed in the center of the sample.
