Product Introduction
The hot wire test instrument 02.06a complies with the requirements of new standards such as IEC60695-2-10:2013, GB/T5169.10-2017, GB 9706.1, GB 4793.1, GB4706.1, etc. It is suitable for heat and fire resistance tests of electrical and electronic products, household appliances and their materials, simulating the thermal stress caused by hot components or overloaded heat sources or ignition sources in a short period of time, aiming to conduct tests to evaluate material properties related to fire risks.
This instrument adopts an original imported integrated chassis, and the control device is located outside the box, which can effectively avoid the influence of external factors on the test results and prevent smoke leakage; The instrument can display voltage, current, temperature, and can display and record ignition time (TI) and flame extinguishing time (TE), which facilitates testing and result recording.
Product Parameters
Test box: Comes with an original imported integrated box, and the control device is located outside the box, which can effectively avoid external factors affecting the test results and prevent smoke leakage, maintaining the safety of the laboratory environment. Box test volume ≥ 0.75m3, black background, background illumination ≤ 20lx
Test circuit: In accordance with the requirements of IEC60695-2-10:2013 standard, a constant current source is used without temperature compensation or temperature holding circuit. The instrument is equipped with a true rms ammeter, and the temperature of the heating wire is manually set and adjusted to ensure stable voltage of the command variable (heating wire) during the experiment. The temperature controller is protected from the feedback effect of the command signal (thermocouple). The temperature range of the heating wire is adjustable from room temperature to 1000 ℃, and the temperature is measured by a K-type first-class standard thermocouple, which meets the requirements of IEC60584-2 standard. The original imported heating wire is 4mm ± 0.04mm Ni/Cr (80/20), with a specially designed standard ring shape; Original imported insulated high-temperature resistant K-type armored thermocouple, armored sleeve heat-resistant to 1100 ℃, diameter 1.0mm
Heating temperature of hot wire: room temperature~1000 ℃, temperature fluctuation<3 ℃, temperature verified with silver foil
The temperature displayed on the thermometer is 960 ℃± 10 ℃
