The hot wire combustion testing machine is used to detect the thermal stress caused by heat sources or ignition sources such as hot elements or overload resistors in a short period of time, in order to evaluate the standard level of related products.
Applicable standards:
IEC60695-2-10-13, GB/T5169.10-13-2006 "Basic test methods for hot wire/hot wire, hot wire test apparatus and general test methods"; UL746A, IEC829, DIN695, VDE0471.
Main parameters:
1. Temperature range: 500-1000 ℃, digital adjustable;
2. Temperature error: ± 10 ℃ (500-750 ℃), ± 15 ℃ (750-1000 ℃), temperature measurement instrument accuracy: ± 0.5 level;
3. Temperature sensor: Φ 0.5K armored thermocouple, imported thermocouple;
4. Apply pressure to the sample: 0.8N~1.2N, and limit the depth of pressing to at least 7mm;
5. Timing range: adjustable within the range of 0-99 minutes and 99 seconds;
6. And it has a timer with ignition time (Ta, generally set to 30 according to standard requirements), second holding time (Ti), and flame extinguishing time (Te);
7. Time error: ± 1s;
8. Igniting cushion layer: 10mm thick white pine wood board, covered with 12g/m2~30g/m2 standard silk paper, 200mm ± 5mm below the burning wire.
