Description of Mask flame retardant tester: This test instrument is mainly used for electronic and electrical components or parts under fault or overload conditions, which may reach excessively high temperatures or ignite parts near them. The glow-wire test simulates the thermal stress caused by a heat source or ignition source such as a hot element or an overload resistance over a short period of time, the simulation technology is used to assess fire hazard. It is suitable for electrical and electronic products, components, household electrical appliances components with plastic non-metallic insulation materials and parts, such as: switch shell, relay sockets, etc.
Testing principle: The mask flame retardant performance tester heats the heating wire of the specified material and shape (¢ 4 Ni80 / Cr20) with high current to the test temperature for 1 minute (550 ºC ~ 960 ºC), then scorches the test sample vertically at the specified pressure (1.0N) 30s, depending on whether the test article and the bedding ignite or hold the time to determine the fire hazard of the finished electrical and electronic equipment; determine the ignition performance, ignition temperature (GWIT), flammability and flammability index of solid insulating materials and other solid combustible materials.
Purpose and features It is used to determine the tendency of mask products to prevent burning and continued burning, smolder and carbonization.
6) The force applied by the glow wire to the sample
1.0 ± 0.2 N, and limit the compression depth to 7 mm ± 0.5 mm
7) Glow wire
Glow-wire is a standard sized ring made of 4mm diameter nickel/chromium (80/20) wire.The diameter of the glow-wire before bending is 4.0 +/ -0.04mm, and it shall not be reduced to 90% after bending. Other sizes are made according to the error requirements of the standard;
8) Moving speed of the top of the glow wire approaching and leaving the sample
10mm / s-25mm / s
adjustable from 0 to 99 minutes and 99 seconds, accuracy: ± 1 second Glow time (Ta), can be set, ignition duration (Ti) and flame extinction time (Te) can be recorded, original imported
10) Product features
The tester's control system is automated. After startup, the trolley that holds the sample will automatically run the sample to the glow wire, and will automatically return when the set glow time is reached. The interior is a black background with ventilation and lighting device, time, temperature digital display, easy to observe and record.
11) Power supply
AC 220V, 50Hz
