Meaning of the IP of the Grade of Protection of the Solar Road Studs

There is an essential parameter for the solar road studs, which is the IP protection grade, and what does the IP protection grade really mean?
It is drafted by the International Electro-technical Commission, and graded the electrical appliances according to the features of dustproof, anti-invasion of foreign objects (including the energized parts where the tools and fingers cannot touch), anti-moisture and waterproof. The IP protection grade is composed by two numbers: the first represents the grade of dustproof and the anti-invasion of foreign objects, and the second one represents the grade of the anti-moisture and the waterproof. The protection level is higher, if the number is bigger.

Waterproof solar road stud

The first number:
0 represents no protection. There is no protection against the invasion of solid objects.
1 represents it has the protection against the invasion of big objects, which can prevent the invasion of the object whose diameter is over 50mm.
2 represents the invasion of objects of the middle sizes and prevent the connection of the fingers and the live part or the moving part inside. And it can prevent the invasion of the solid object whose diameter is 12mm.
3 represents the invasion of objects of the small sizes and prevent the connection of the tools or wires whose thickness are over 2.5mm, and the live part or the moving part inside. And it can prevent the invasion of the solid object whose diameter is 2.5mm.
4 represents the invasion of objects of the particles and prevent the connection of the tools or wires whose thickness are over 1mm, and the live part or the moving part inside.
5 represents the protection against dust accumulation and prevent the connection of the live part and the inside moving part. It can prevent the solar road studs against the dust accumulation, for it cannot prevent the entering of dust totally, but the amount of the dust enter inside will not influence normal work of the wire.
6 represents the prevention against dust and prevent the connection of the live part and the inside moving part. It can totally block the entering of dust.

Waterproof solar road stud

The second number:
O represents there is no special protection.
1 represents the protection against the water drop straightly. There is no influence if the water drops straightly.
2 represents the protection against the water drop in certain angle. There is no influence if the water drops straightly or in the range of 15.
3 presents the protection against the spray drop. There is no negative influence if the water drops straightly or in the range within 60°.
4 represents the protection against the splash dispersal. There is no negative influence on the facility if the water splash on it from any direction.
5 represents the protection of injected water. The water injected to the facility cannot influence the working of it from any direction.
6 represents the protection against flood. The water enters to the facility cannot exceed to the certain amount in the temporary flood in rainstorm season.
7 represents the protection against immersion. The water enters to the facility cannot exceed to the certain amount when it immerges in water in regulated pressure and time.
8 represents the protection against submerge. The water enters the facility cannot exceed to the certain amount if it submerges in the water.
