How the Table

If you want to know which dust and water protection as a specific dual SIM phone offers, you can read its IP class so: Locate the first number specified in the leftmost column, after the second number shown in the second column from the left ,

Example : A cell phone has protection IP57. Then this means that it is dust-protected (Paragraph 5, left column) and provides protection against temporary immersion (Paragraph 7, second column from the left).
Exception : If manufacturers want to call one of the two information only or can, the other digit is replaced by an "x". So would IPx8 awaterproof phone call whose protection is unclear to foreign bodies.
