Protective Clothing Thermal Conductivity Tester

Présentation

The protective clothing thermal conductivity tester is a professional equipment specially used to detect the heat transfer characteristics of protective clothing.

Normes applicables

ISO 11092:2014 ASTM D1518-17

ASTM F1868 ISO 5085-1 ISO 9920

Structural composition

Thermal environment control module:

can accurately set and maintain the temperature of the high temperature side, simulate human fever or external high temperature environment, and usually can adjust the temperature range to a wide range, such as 30℃ - 60℃.

Cold environment control module

used to maintain a constant temperature on the low temperature side, forming a temperature difference with the hot environment. Common temperature control methods include water cooling or air cooling to ensure temperature stability.

Application significance

In the medical field, it helps develop and screen more comfortable medical protective clothing to prevent heat accumulation and discomfort caused by long-term wearing for medical staff, and reduce the risk of heat stroke; in the industrial and fire protection fields, it can evaluate the thermal insulation effect of high-temperature protective clothing to ensure the safety of workers in high-temperature environments and prevent heat injuries.

Paramètres techniques

Heat Source: Nine T-150 infrared quartz lamps, providing a heat radiation flux of 10 kW/cm² to 50 kW/cm².

Protective Grid: The anti-slip grid is opened and closed to control whether the sample receives the heat generated by the heat source.

Specimen Holder and Mounting Plate: The holder is used to position the sample. The mounting plate is 150 mm x 150 mm and 1.6 mm thick.

Sample Holding Plate: A 149 mm x 149 mm x 15 mm steel plate with a 130 mm x 130 mm hole in the center.

Spacer: 128 mm x 128 mm x 6.4 mm with a 110 mm x 110 mm hole in the center.

Data Acquisition System: Real-time recording of temperature changes and heat transfer rate.

Control System: Pneumatic control unit and heat-shielded specimen holder ensure test stability.

Professional Software: Supports heat transfer index calculation and generation of multi-sample averages.
