IPx9K testing, Test Standard comply with DIN 40 050 Part 9

What is the difference between IPX9K testing and IPX9 testing ? Why add a “K” to the testing standard, IPX9K test specification, and what is the meaning of it ?

IPX9K and IPX9 both come from the waterproof grade standard: ISO 20653-2013 and GB 4208-2017. IPX9 mentioned in GB4208-2017 test standard be introduced is the latest version (Come into force date: Feb, 2018), It can be understood that this standard was introduced by the committee from other standards. So the original test standard came from ISO 20653. IPX4K, IPX6K, IPX9K etc all has “K” term, So we should understand the relationship between the IPX9 and IPX9K.

What is the “K” mean of IPX9K ? “K” refers to the test pressure requirements. IPX9K testing has a 10000 Kpa pressure requirement, and extended to other protection grade, for example, 4K, 6K, actually it keeps the requirement of the water spray pressure. So we should know that “K” mainly mentioned water pressure requirement.
