Flame Retardant Testing Equipment
Name：LFY-626 Smoke Density Method Plastic Combustion Performance Tester
Details
The main purposeThis instrument is suitable for measuring the specific optical density of materials produced by radiation or burning under specified test conditions. The specific optical density is the specific optical density value calculated from the specified test chamber volume, optical path length, and the measured transmittance of the test area. The maximum optical density value is used to indicate the optical density of the material.
Technical index
1. Chamber size: high 914mm×width 914mm×depth 610 mm;
2. Light source: 6V incandescent tungsten;
3. Light transmittance measurement accuracy: less than ±3% of the maximum reading of each scale range;
4. Heating wire power of radiant furnace: 600 watts
5. The centerline of the horizontal combustion tube is from the lower edge of the sample box opening: 6.4±0.8mm
6. Fuel: more than 95% propane, flow rate is 50cm3/min, air input is 500cm3/min;
7. Sample: (75±0.5)mm×(75±0.5)mm×(1±0.2)mm.
