IP Testing Equipment is short for ingress protection testing equipment. They consist of a series of devices used to assess the extent of protection of persons against access to hazardous parts inside the enclosure and protection of the equipment inside the enclosure against ingress of solid foreign objects and (or) against ingress of water.
The IP code indicates the degree of protection provided by an enclosure. Different letters and numerals following the “IP” represent different protection levels. The access probes, object probes, dust chamber and waterproof test equipment, constitute the IP testing equipment. The probes are used to test the protection ability of persons or equipment indicated by the numerals and additional letters in the first and third positions after the “IP”. The dust chamber is suitable for testing the dust-proof ability of the enclosure indicated by the first numeral. The waterproof test equipment is used to test the waterproof performance of the enclosure indicated by the second numeral.

What Is Ingress Protection Code and What Is Its Structure?
Ingress Protection Code is abbreviated as IP Code. It is a coding system composed of letters and numbers to express the extent of protection offered by an enclosure against access to hazardous parts, ingress of solid foreign objects, ingress of water, and to give additional information in connection with such protection.
The structure of the IP code as below:
| Elements | IP | First characteristic numeral | Second characteristic numeral | Additional letter (optional) | Supplementary letter (optional) |
| Explanation | Code letters (international protection or ingress protection ) | Numerals from 0 to 6K or letter X | Numerals from 0 to 9K or letter X | Letters A, B, C, D | Letters M, S |
What Is Ingress Protection IP65?
Code “IP65” contains 2 characteristic numerals of “6” and “5”.
“6” means the degree of protection as below:
Protect the equipment inside the enclosure against ingress of dust
Protect persons against access to hazardous parts with a wire having a diameter of 1.0 mm and greater
“5” means the degree of protection as below:
Protect the equipment inside the enclosure against water jets from any direction.
What Is the IPX Waterproof Rating Chart?
The IPX Waterproof rating chart summarizes the waterproof protection ability of the casing to its internal equipment under different waterproof grades from IPX1 to IPX9K. The larger the value, the more severe the requirements for the waterproof level. Specific IPX rating descriptions are described in the table below. You can choose the corresponding test items according to the waterproof requirements you want to achieve.
The IPX rating table are as below:
| IPX Code | Degree of Protection |
| IPX0 | None |
| IPX1 | Protect the equipment inside the enclosure against vertical water drips |
| IPX2 | Protect the equipment against vertical water drips with the enclosure inclined by 15° in four directions, respectively |
| IPX3 | Protect the equipment inside the enclosure against spraying water |
| IPX4 | Protect the equipment inside the enclosure against splashing water |
| IPX4K | Protect the equipment inside the enclosure against splashing water with increased pressure |
| IPX5 | Protect the equipment inside the enclosure against water jets |
| IPX6 | Protect the equipment inside the enclosure against strong water jets |
| IPX6K | Protect the equipment inside the enclosure against strong water jets with increased pressure |
| IPX7 | Protect the equipment inside the enclosure against the effects of temporary immersion in water |
| IPX8 | Protect the equipment inside the enclosure against the effects of continuous immersion in water under conditions agreed upon by the interested parties |
| IPX9/IPX9K | Protect the equipment inside the enclosure against high pressure and high temperature water jets |
What’s IP67 Test Procedure?
According to the requirements of the relevant standards for the protection level of the equipment, the products that pass the ip67 test can be completely dust-proof and withstand water penetration after being temporarily immersed. That is, the product’s enclosure can prevent dust from entering the inside of the device. After putting the product into the water at a specified depth for half an hour under a normal temperature environment, it will not cause harmful effects on the product or impair its performance.
The IP67 test is performed in 2 sections.
Section 1: Test the IP6X dust resistance
Put the sample into a dust chamber with talcum powder of specified mass, then start the machine to keep the talcum powder in suspension in the chamber, fully exposing the sample to the dust environment, and continue the test for a specified duration (depending on sample properties as per standard requirements). After the test is completed, disassemble the sample shell for inspection. If there is no dust intrusion inside the shell, it is considered to pass the test.
Section 2: Test the IPX7 Water resistance
Immerse the sample into the immersion tank for 30 minutes at a specified depth per standard. After the test time is up, remove the sample from the tank. Check whether the sample is still functioning properly. If there is no negative impact on the normal operation of the equipment and it weakens its performance, the test is deemed to be passed.
