IPCode: Protection level of the shell

This standard describes a system for classifying the protection level of electrical equipment enclosures. Proposed by the European Committee for Standardization of Electronic Technology, the protection level of electrical equipment enclosures is divided into many categories, and according to different numbers, the protection level of products can be quickly and conveniently determined.

By codeIP54For example:

IPIndicating that this is a standard model

5 Indicate the level of protection in the solid

4 Indicate the level of protection in the liquid

Protection level (* * digits in the code) **Characteristics

1 The anti diameter is50mmEven larger solid particles

Object * * or50mmSolid particles with a diameter cannot penetrate completely.

2 The anti diameter is12.5mmEven larger solid particles

Object * * or12.5mmSolid particles with a diameter cannot penetrate completely.

3 The anti diameter is2.5mmEven larger solid particles

Object * * or2.5mmSolid particles with a diameter cannot penetrate at all.

4 The anti diameter is1mmEven larger solid particles

Object * * or1mmSolid particles with a diameter cannot penetrate at all.

5 Dust protection cannot completely prevent dust from entering, but it will not hinder the normal operation of the instrument and reduce safety

The degree.

6 Dust is trapped and cannot enter the object. The entire diameter cannot exceed the gap in the shell

1 Water droplets that prevent vertical falling will not cause harmful effects

2 When the shell lifts up, it can reach15Prevent water droplets from falling vertically at °

When the shell tilts at any angle on either side of the vertical axis, it should not exceed15At ° C, vertically falling water droplets will not cause harmful effects

3 Waterproof fog on any vertical side with no more than60Spray at an angle of ° will not cause harmful effects

4 Splashing water onto the casing from any direction will not cause harmful effects

5 Spraying water from any direction onto the casing will not cause harmful effects

6 Strong water spray against the shell from any direction will not cause harmful effects

7 Prevent short-term soaking at room temperature and pressure, when the shell is temporarily soaked in1MDeep water will not cause harmful effects

8 Both the manufacturer and the user agree to prevent continuous immersion, but the conditions are different

7 Under harsh conditions, continuous immersion in water will not cause harmful effects.
