According to EN60529: 2000 class IP67 protection standard test method of the first eigenvalue (6) test conditions protective of invasive alien solids IP6X (dust density), dust air mixtures vacuum test. Vacuum: ≤ 2kpa (20mbar) Test Time: 8h Test dust: talcum powder particle diameter distribution: ≤ 50μm ~ ≥ 75μm second characteristic value (7) Test conditions: protection of water intrusion protection IPX7 test system test device: Dip Pool Distance: from the chassis top surface depth of 1 meter test time: 30 minutes of the first eigenvalue (6) of the definition: there is no dust intrusion.

    The second feature value (7) is defined: When the chassis immersed in a standard pressure of water within the specified time the water did not infiltrate into the chassis can cause the number of water hazards.
