ISO 20653:2013 pdf free.Road vehicles一Degrees of protection (IP code)
Tables 2 and 3 contain short descriptions of the degrees of protection with the relevant requirements.If the same degree of protection (identical code element) for protection against foreign objects and access is required, then both requirements are indicated by the first code element.
If different degrees of protection for both protection types are required, then an additional letter shall be used. In this case the first code element only defines the protection against foreign objects and the additional letter indicates the protection against access.
Additional letters may only be used if:
一the degree of protection against access is higher than indicated by the first code element, or
一only the degree of protection against access is to be indicated (first code element substituted by X).
The indication of a degree of protection against access and foreign objects always includes the preceding degrees of protection.
Table 4 contains short descriptions of the degrees of protection with the relevant requirements.Up to and including degree of protection 6K for the protection against water, the designation implies compliance also with the requirements for all lower degrees of protection.
For degrees of protection against water 7, 8 and 9K, lower degrees of protection up to and including 6K are not covered by the designation. In such cases where a lower degree of protection up to and including 6K is required in addition to protection against water 7, 8 or 9K, it shall be indicated separately, e.g.IPX4K/IPX7, IPX5/IPX7, IPX6K/IPX8 and IPX6K/IPX9K.
The marking of an enclosure with the IP code IP34K means:

(4K) Protection of electrical equipment within the enclosure against harmful effects resulting from water splashing against the enclosure with increased pressure from any direction (pro-tection against water). ISO 20653 pdf download.
