IP标准说明

IP stands for 'Ingress Protection'
An IP number is used to specify the environmental protection of enclosures
around electronic equipment. These ratings are determined by specific
tests.
The IP number is composed of two numbers, the first referring to the
protection against solid objects and the second against liquids. The
higher the number, the better the protection.
Note: All Aceeca devices are manufactured and tested to IP67 standards.
