    • The cable glands with a double-orifice sealing system, a test mandrel parallel to the least worthy of the anchorage scope of the most more modest slot of the cable gland are fixed into the littlest slot of a sample, and each exceptional slot is stopped with an attachment equivalent to the most minimal worth of its sealing range.
    • Perform the test according to the temperature provided by the supplier.
    • Place the samples in the refrigerator for 8 hours before the test. Test temperature tolerance is ± 2 °C.
    • You can perform the test inside the refrigerator.
    • The impact point place should be considered the weakest place.
    • Mount the sample on a steel base.
    • The mass should be fitted with an effective head of hard steel as half of the globe of 25 mm in diameter.
    • The base ought to have a mass of at any rate twenty kg or be unyieldingly inserted or fixed within the floor.

    The impact energy is applied according to the following impact values chart:

    Q.36 How to perform ingress protection test of Metal Cable Gland?

    Water-tightness is crucial for electrical equipment safety. Humidity can easily cause downtime and risk.

    The water is splashed with a nozzle on the installed metal cable gland. The water flow rate during the test is a water jet of 100 liters in one minute.

    The water jets are applied as per the IP rating of the cable gland. The test vessels along with seals can also be deluge into a dunking water tank for the testing purpose of IPx7.

    The result will be successful if the water does not enter into the cable gland and does not create any problem with that.
