IP Water Test for Motor Vehicle

In industrial production, especially products that can be used outdoors such as electronic appliances, there will be different levels of dust proof and waterproof requirements for equipment. The protection level (IP code/dust proof and waterproof) of automation instrument equipment is an important indicator to ensure the normal operation of equipment and ensure product safety and reliability. Then, when selecting and using instrument, we should pay special attention to the protection level of instrumentation, which is of great significance for correct product selection and product installation and use. Below, I will introduce the relevant knowledge of IP water ingress protection level for you in detail.

Learn Something About IP Ingress Protection Ratings

IP (international protection) level and waterproof test standard is an international protection and waterproof test standard drafted by the IEC(international electrotechnical commission).

International Electrotechnical Commission standards IEC 60529–60598

Currently LIB test chambers can perform all these tests.

Its protection level is composed of two numbers. The first number indicates the level of electrical appliances from dust, to prevent the invasion of foreign objects. The second number indicates the degree of tightness of electrical appliances against moisture and waterproof intrusion. The larger number indicates that its protection level is higher.

IP Testing Required for IEC 60529 Rating
Dust (First Number)	Moisture (Second Number)
IP Ox - No Protection	IP x0 - No Protection
IP 1x - Objects > 50mm	IP x1 - Protected Against Vertically Dripping water
IP 2x - Objects > 12mm	IP x2 - Protected Against Dripping water (15°tilted)
IP 3x - Objects > 2.5mm	IP x3 - Protected Against Sprayed water
IP 4x - Objects > 1mm	IP x4 - Protected Against Splashed water
IP 5x - Dust Protected (Vacuum)	IP x5 - Protected Against water jets
IP 5x - Dust Protected (Non-Vacuum)	IP x6 - Protected Against Powerful water Jets
IP 6x - Dust Tight	IP x7 - Protected Against Effects of Temporary lmmersion
	IP x8 - Protected Against Continuous Immersion
	IP x9 - Protected Against water with High Pressure/ Steam Jet Cleaning

IP protection level cases

1. Home appliances are generally IP20. If there is no special requirement, IPX0 is usually market. The X in IPX0 indicates that the first one is not considered.

2. General indoor lamps are IP20; Dust resistance is level 2 (to prevent the entry of objects up to 12 mm) and is not waterproof.

3. Outdoor lamps are generally IP44. To prevent objects larger than 1 mm from entering and sprayed water from entering.

4. IP54 for indoor spaces with large moisture and dust, such as bathrooms, kitchens, and canopies.

5. IP65 for outdoor floodlighting.

6. IP67 for buried lamps, while ensuring good water dispersion in the soil at the bottom of the lamps.

7. Underwater decorative lamps IP68.

The protection level commonly used in electronic communication products are

IP 57 (This requires dust proof and short-term immersion in water will not be affected),

IP 65 (This requires dust proof and splash-proof),

IP 67 (This requires dust proof and short-term immersion in water will not be affected).

Whether IP 65 or IP 67 is used depends on the application and the different test standards. IP 67 is not always better than IP 65. Components that meet the IP 67 standard do not necessarily meet the IP 65 standard.

IP Water Test for Motor Vehicle

In the testing of auto parts and other products, the IP code waterproof test is used to verify the tightness of the product and provide the reliability basis for product quality. The most demanding waterproof test level in ISO16750, DIN40050, ISO20653 series is IPX9K, including the domestic automotive industry standard QC/T417.1-2001 automotive wire harness plug-in test.

The following mainly introduces IPX4 and IPX9K.

(1)IPX4

a. Pendulum tube splash water test

Test equipment and specimen placement:

Select the pendulum tube of the appropriate radius, so that the height of the sample table is in the position of the diameter of the pendulum tube, and place the specimen on the sample stage so that the distance from the top to the sample nozzle is not more than 200mm, and the sample stage does not rotate.

Test conditions:

The water flow rate is calculated according to the number of water spray holes of the pendulum pipe, and each hole is 0.07 L/min; The water spray area is the water spray of the water spray hole in the 90° arc on each side of the midpoint of the pendulum tube to the sample. The test sample is placed in the center of the pendulum tube semicircle. The pendulum pipe swings 180° on each side of the perpendicular line, for a total of about 360°. Each swing (2×360°) is about 12s.

Test time: 10 min.

JIS D 0203 Moisture, Rain and Spray Test

JIS-D-0203 testing is an ingress protect test standard published by the Japanese Standards Association.

This automotive ingress protection testing standard applies to a number of parts. The scope of this IP Code testing specifies the methods of moisture resistance and waterproofness for automotive parts.

JIS D 0203 testing labs must put auto parts through a rigorous test plan that includes a variety of ingress protection tests. This testing of the waterproofness of enclosures includes the following tests.

R1 – Rain Test

This test investigates the function of the parts subjected to droplets. The duration of this test is 10 minutes. The water temperature is to be 32 degrees Celsius.

R2 – Rain Test

This ingress protection testing determines the function of the parts subjected to indirect wind and rain or spray. The duration of this test is 10 minutes. The water temperature is to be 60 degrees Celsius.

Spray Testing

Spray testing is an ingress protection test using specific nozzles to spray water onto a unit from a certain distance and at a certain flow rate. JIS D 0203 testing labs must follow two testing protocols when completing spray testing.

S1 – Spray Test

The spray testing in this testing is to investigate the function of the parts subjected to direct wind and rain or spray. The duration of this test is 30 minutes. The flow of the water spray is 24.5 liters per minute minimum.

S2 – Spray Test

This spray testing is to investigate the function of the parts subjected to heavy water spray. The duration of this test is one hour. The flow of the water spray is 39.2 liters per minute minimum.
