Product Description Product DescriptionThis equipment evaluates the static waterproof integrity of safety footwear (e.g., boots), rubber gloves, waterproof linings, and PPE under sustained hydrostatic pressure, complying with ASTM F2413-18 §5.2, ISO 20344:2022 §5.11, EN ISO 20344, and related standards.Principle:Inflating method: Seal the mouth of the test shoe (boot), fill the sealed shoe cavity with compressed air at a certain pressure, and place it in a water tank so that the water surface is within 75mm of the test shoe mouth. After a certain period of time, observe whether there are bubbles on the surface of the shoe.Soaking method: Immerse the test shoe (boot) in water until the water surface is within 75mm of the shoe opening. After soaking for a certain period of time, take it out and check if there is water seeping into the shoe. Working Principle:1. Specimen Setup:Test shoes are mounted on mechanical "feet" (simulated lasts) and partially submerged in a water tank (depth-adjustable).Colored water is used for visual leak detection.2. Dynamic Flexing Simulation:The forefoot or heel is bent at a programmable angle (typically 22°-60°) and frequency (e.g., 60±6 cycles/minute as per EN ISO 20344).Motion replicates human gait to stress seams, soles, and uppers.3. Leak Detection:Automatic sensors (e.g., conductivity probes or electronic moisture detectors) instantly halt testing upon water ingress and record the failure cycle count368.Alternative: Inspect for dyed-water penetration after preset cycles.
