Leak Proofness Tester For Testing Lab Workshop.
Leak Proofness Tester - For Testing Lab The body of waterproof protective footwear or gumboots shall be protected against ingress of water encountered when the wearer walks through water. The ability of waterproof protective footwear to stop water from entering them is determined by closing their top opening with a watertight metallic or rubber end plug and immersing it up to its top edge under water. Compressed air at a specified pressure is introduced in the footwear and any leakage of air from it into water is examined visually for a constant stream of air bubbles. The footwear under test is kept vertical inside the water bath used for its immersion by placing a number of large diameter steel balls in it.
