IEC standard 60529,

ip 4 waterproof mean = IPX4 Water Resistance

IPX5 – Protects from water jets at any direction

The protection level of IP55 is level 5, which represents wire protection (diameter greater than or equal to 1mm) and prevention of harmful dust accumulation. ... IP65 has a protection level of 6, which means completely preventing dust from entering.

Ingress Protection Code

The standard aims to provide users more detailed information than vague marketing terms such as waterproof. For example, a cellular phone rated at IP68 is "dust resistant" and can be "immersed in 1.5 meters of freshwater for up to 30 minutes". Similarly, an electrical socket rated IP22 is protected against insertion of fingers and will not be damaged or become unsafe during a specified test in which it is exposed to vertically or nearly vertically dripping water. IP22 or IP2X are typical minimum requirements for the design of electrical accessories for indoor use.The digits indicate conformity with the conditions summarized in the tables below. The digit 0 is used where no protection is provided. The digit is replaced with the letter X when insufficient data has been gathered to assign a protection level.There are no hyphens in a standard IP code. IPX-8 (for example) is thus an invalid IP code.^[2]This article summarizes a combination of IEC 60529 (also EN 60529) and other standards, such as ISO 20653. The original ********s are available for purchase, and have important and specific requirements that cannot be fully reprinted due to copyright restrictions. This often includes drawings specifying the required test equipment, such as the shape of water nozzles used for water jet testing. Additional standards are often referenced that may contain important information. One must refer to the latest revision of the required standard when conducting formal tests for agency certification.

The second digit indicates the level of protection that the enclosure provides against harmful ingress of water.^[5] The ratings for water ingress are not cumulative beyond IPX6. A device that is compliant with IPX7 (covering immersion in water) is not necessarily compliant with IPX5 or IPX6 (covering exposure to water jets). A device that meets both tests is indicated by listing both tests separated by a slash, e.g. IPX5/IPX7.
