waterproof gradeiP67 andiP68 mean?

waterproof means that the equipment has Class 6 dustproof and Class 7 waterproof capability. Specifically, the IP67 level certification equipment can protect dust from entering (overall prevention of contact, protection of dust penetration), and at the same time can protect short-term liquid immersion (anti-immersion), and can have a maximum anti-immersion capacity of 30 minutes in water up to 1 meter deep.

iP68waterproof refers to a waterproof rating of 8. That is to say, under the specified time and the specifiedwater depth, the article will not be damaged due to immersion and cannot be used.

In this standard, for the protection of the equipment shell against foreign objects, the format of the IP grade is IPXX, where XX is two Arabic numerals, and the first mark number indicates the contact protection and foreign object protection grade.

The second marking number indicates the waterproof protection level. IP is the code name Ip usedinternationally to identify the protection level. The IP level consists of two numbers. The first numberindicates dustproof. The second number is waterproof. The larger the number, the better the protectionteam leader.
