Liquid Protection

You will also see the second di

gital behind IP stands for protecting from liquids, such as water. There are 9 grades of liquid protection with bigger and higher protecting grades.

Other Protection

Sometimes, there are also some letters to stand for protecting other objects. This is not often used.

IP Rating Chart

Below is an IP rating chart for your reference.

What Does The First Digit of The IP Rating Mean?

The first digit after IP mainly ranges from 0 to 6 to indicate the diameter or mesh of foreign objects or dust.

0: There is no protection;

1: The diameter of the object is 50mm;

2: The object is at 12.5mm;

3: The diameter of the of the object is 2.5mm;

4: The diameter of the object is 1mm;

5: It is an object with a dust level;

6: Even tiny dust can be prevented from entering.

What Does The Second Digit of The IP Rating Mean?

The second digit after IP ranges from 0 to 9 to indicate the level of protection against water intrusion with different heaviness.

0: There is no protection;

1: It can prevent water from entering vertically.

2: It can prevent water from entering with an inclination angle of 15 degrees.

3: It can prevent spray water from entering with a tilt of 60 degrees.

4: It can prevent splashing water at any tilt angle from entering.

5: It can prevent the sprayed water (nozzle 6.3mm, pressure 30kpa, head 3m) from entering.

6: It can prevent the entry of relatively powerful water jets (nozzle 12.5mm, pressure 100kpa, head 3m).

7: It can be immersed in water (depth 1m, time 30 minutes) and can also prevent entry.

8: It can enter the water more than 1m without leaking (the test time is usually marked by the manufacturer).

9: It means that immersing in high-pressure and high-temperature water can prevent water from entering.

What Does Letter Digit of The IP Rating Mean?

The letters are sometimes used to indicate protecting your device from other objects, such as oil, gasoline, etc. 

F: Fuel resistance

H: High voltage device

M: Moving status underwater

S: Standstill status under water

W: Weather conditions

What IP Ratings Of Packaging Equipment Have? 

Protecting the electrical enclosure of the packaging machine from dust and water is a compulsory requirement. Especially for dusty packaging environments, such as the flour and coffee industry. And waterproof protection for liquid packaging, such as cosmetics.

Electrical Room Use No Water

The motor and pneumatic parts might fail if it’s invaded by dust or moisture. So the packaging machine manufacturers will consider the IP ratings when fabricating it.

There are several IP ratings for packaging machines:

      1. IP54. Normally protecting your machine from a normal dusty environment or water splashing.

      1. IP65. Completely protects your machine from fine dust entering and can use low-pressure water to jet.

      1. IP66. Completely protected from fine dust and with strong-pressure water to jet.

      1. IP67. Completely protecting the machine from fine dust invasion, and suits for water jet washing under shallow water with a short continuous time.

      1. IP68. Completely protects the machine from fine dust entering, and can immerse it in the deep water.
