Dust and water proof requirements for the product, according to test specification IEC / EN 60529. There is a set of standard test equipment, methods, time and compliance as long as it is necessary to prevent solid objects such as arms, fingers, metal bars, wires, and even dust or liquids (water) from entering the product Of the standard.

        The full name of the IEC / EN 60529 standard is Degrees of protection provided by enclosure (IP code), meaning the degree of protection provided by the product enclosure. IP is the abbreviation of International Protecion, which means internationally recognized level of protection, more and more countries are in use, only in the United States and Canada, dust and waterproof still in use of its national standards such as UL50 and CSA.

         In general, most of the IEC or EN product standards (product standard), in determining its dust and water requirements, will be more for the IEC / EN 60529 conditions, such as test conditions or judgments, make a number of changes , To meet the needs of their special products. These standards, such as IEC / EN 60598 lighting products, IEC / EN 60335 household electrical appliances, IEC / EN 60558 power supply standards, and even IEC / EN 60950 information product standards, are often dust and water testing requirements.

Products need to dust and waterproof test, most of its use in outdoor or wet conditions, such as lighting, advertising, air conditioning products, bathroom supplies, washing machines, swimming pool supplies, sauna supplies, aquarium supplies, the power supply products Devices, and even information products are increasingly emphasizing the function of dust and water.
