Overview
This tester is suitable for inspection and evaluation of the combustion characteristics of plastic materials. It is designed and manufactured according to the relevant provisions of the US UL94 standard and GBT2408 standard "Flammability Test of Plastic Materials for Equipment and Appliance Parts". Horizontal and vertical flammability tests are carried out on plastic parts of equipment and appliances. Gas flow rate meter is equipped to adjust the flame size, simple and safe operation. This instrument can evaluate the flammability of materials or foam plastics such as: V-0, V-1, V-2, HB, 5V, HF-1, HF-2, HBF grades.
Features
1. Equipped with lighting device, gas extraction device, gas Flow rate regulating valve, gas pressure gauge, gas pressure regulating valve, gas Flow rate meter, gas U-type pressure gauge and sample fixture; 2. With combustible gas concentration detection alarm function, when the combustible gas concentration in the combustion box exceeds the standard, the machine automatically cuts off the gas supply and sends an alarm prompt, and starts the exhaust system to start ventilation until the air mass in the combustion box returns to normal; 3. Test space ≥ 0.5m ³, with Glass observation door; 4. Flame time and afterflame time can be set in a wide range; 5. The combustion angle can be adjusted; 6. Flame height adjustable; 7. Motor drive front and rear positive spline; 8. Load type universal caster, easy to move; 9. Can work continuously.
Principle
This instrument is designed according to UL94 and GBT2408 standards. By adjusting the gas Flow rate and flame size, the plastic material is tested horizontally or vertically to evaluate its flammability level. During the test, the instrument automatically controls the flame application and afterflame time, and has the function of Safety protection. When the concentration of combustible gas exceeds the standard, it automatically cuts off the gas supply and starts the exhaust air.
Steps
1. Set the flame time and residual flame time; 2. Adjust the combustion angle and flame height; 3. Use the motor to drive the positive spline; 4. Start the test and observe the combustion process; 5. After the test, the instrument automatically treats the exhaust gas.
Notice
- Ensure that it is used under the conditions of applicable Ambient Temperature -10 ° C~ + 50 ° C and relative humidity ≤ 95%; - The altitude does not exceed 2500 meters; - The instrument is suitable for indoor use, Protection Rating IP20; - Pay attention to the flammable gas concentration alarm function to avoid gas leakage; - Check whether the gas supply and exhaust system are normal before and after use; - Pay attention to the use of load-bearing universal casters when moving.
