Device for testing materials for fire hazard by hot wire test method

摘要

The utility model relates to a device for controlling the flammability of polymeric materials, building materials, insulating materials in electrical engineering, ship equipment, aviation, and automotive. A device for testing materials for fire hazard by testing a heated wire, containing a plate on which a stand with a heating wire is fixed, guides, a power supply, a thermocouple, a carriage with a sample attached to it, a load attached to the carriage with a cable, and is additionally equipped with a linear displacement sensor, fixed under the rack, a camera installed opposite the heating wire, while the outputs of the linear displacement sensor and the camera are connected to a computer for statistical processing of the data obtained. The technical result is to increase the accuracy of measuring the parameters of combustibility of materials, namely, measuring the depth of entry of the heated wire into the sample of the test material and the dimensions of the flame formed as a result of contact of the heated wire with the sample. 2 ill.
