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.
