Safety Belt and Hard Hat Testing Equipment
LBT-ZF-622 Thermal Protection Performance Tester
This instrument is suitable for testing the thermal insulation performance of flame‑retardant protective clothing fabrics when exposed to radiant and convective heat sources. A heat source is placed on one side of the test specimen, while a copper calorimeter is positioned on the opposite side. The test is initiated by sliding the sample holder into position; when the sensor reading reaches the threshold corresponding to the human body’s tolerance for second‑degree burns (a sensor temperature increase of 35°C to 40°C), the sample holder is removed from above the heat source. The time required to produce a second‑degree burn is determined with an accuracy of 0.1 second, based on the intersection point of the response curve and the human tissue tolerance curve.
LBT-ZF-631 Protective Clothing Penetration Time Tester
It is used to determine the acid‑alkali penetration resistance of both permeable and impermeable acid‑alkali protective garments, expressed as the acid‑alkali penetration time t. This equipment employs a conductivity‑based testing method: the garment sample is laid flat between two metal electrodes, a test solution is dropped onto the sample, and timing begins. When the test solution penetrates the sample, the electrical circuit is closed, triggering an electrical signal, and the time is recorded. The interval from the moment the test solution is applied to the sample until the signal is detected is defined as the acid‑alkali penetration time for that particular sample.
