                                                                         Ingress Protection (IP)



Level Definition

IP indicates Ingress Protection (Entry Protection). IEC IP protection level is an important part of electrical equipment safety protection. IP and other protection level systems provide a method to classify products by dust-proof, waterproof and anti-collision degree of electrical equipment and packaging.This system is approved by most European countries.It was drafted by IEC (International Electro Technical Commission) and announced in IP code of IED529 (BS EN 60529: 1992).

The protection level is usually expressed by two figures followed by IP and these two figures are used to define the protection level.The first figure indicates the range of dust resistance of the equipment, or the extent to which people are protected from hazards in a sealed environment.I stands for the level of preventing solid foreign bodies from entering.The highest level is 6.The second figure represents the waterproof extent of the equipment.P stands for the level of water resistant and the highest level is 8.


Shell protection level (IP code) is to classify products according to their characteristics of dust-proof, foreign objects invasion proof, waterproof and moisture-proof. The mentioned foreign objects here include tools and human fingers which are not allowed to touch the live parts of the lamps ,so as to avoid electric shock. It is generally composed of two numbers. The first number indicates the level of product dust-proof and foreign objects invasion proof.The second number indicates products' sealing degree of moisture-proof and water invasion proof.The bigger the number is, the higher the protection grade is.For example,for shell protection level (IP code):IPXX.



Dustproof Grade(the first X means)

  Number

Meaning

0

No protection

1

Prevent big solid intrusion

2

Prevent medium-sized solid intrusion

3

Prevent small solid intrusion

4

Prevent intrusion of solid which is larger than 1mm

5

Prevent accumulation of harmful dust

6

Completely prevent dust from entering 


Waterproof Grade(the second X means)

Number

Meaning

1

Water droplets dripping into the shell causes no effect

2

 When the shell tilts to 15 degrees,water droplets dripping into the shell causes no effect

3

 Rainwater falling from 60 degrees to the shell causes no effect

4

Prevent water from splashing in all directions

5

No harm effect will caused when liquid spill on the shell from any direction

6

Can be used in cabin environment

7

Can be soaked in water for a short time

8

Can be soaked in water for a long time under a certain content of pressure
