How you can use the Waterproof test with IP testing

Most electronic and other device manufacturers use the IP (Ingress Protection) scale, which ranges from 1 to 8. IPX1 is the lowest level of waterproofing, indicating that the item is not intended to be used in water or when wet. An IPX8 rating indicates that the item can be submerged and still function properly, though the depth and time of submersion vary. An IP rating of 7 is used for most electronics. This generally means that the device is not intended to be submerged, but if it is and is immediately removed, it should continue to function normally.

ISO 20653 and IEC 60529 are waterproof testing standards. Each of these outlines proper ingress protection testing procedures and ratings. When non-waterproof products become wet, they can cause operation failure, corrosion, mould, electrical hazards such as fire or shock, or other physical damage.

The following are tests that can and have been conducted

Waterproof testing of medical alert devices to International Electrotechnical Commission (IEC) IP code rating IPX6 is required in a laboratory.
• A materials laboratory is required for ASTM testing for membrane waterproofing to ASTM C836, Standard Specification for High Solids Content, Cold Liquid-Applied Elastomeric Waterproofing Membrane for Use with Separate Wearing Course.
• A consumer products performance laboratory is required for clothing waterproof testing. MIL SPECs or other industry standard tests
• An accredited UK laboratory is required for construction building product testing of flexible sheets for waterproofing to BS EN 12691, as well as impact resistance determination to BS EN 12730. Static loading resistance and EN 1847 for building products are determined.
• Methods for exposing oneself to liquid chemicals, such as water.

Ingress Protection Rating

The Ingress Protection (IP) rating describes the type and degree of ingress protection provided by an enclosure. An IP rating is obtained through the use of standardized tests. The ratings are divided into two categories: solid bodies (foreign objects and dust) (the first number after “IP”) and liquids (such as water) (the second number after “IP”).

Testing & Test Plan Support

Water and dust tests for the IEC 60529 standard are possible with LISUN water proofing test equipment on a variety of products. IP testing can be included in customer-specific test plans. The testing procedure is divided into two steps.

The device is first exposed to either solids/dust or water using a standardized protocol. The functional test is the next step. The latter can be either an optical inspection or a more focused functional test, both of which can be performed at our IP test facility or at the customer’s location.

Dust Testing

Medical devices and consumer electronics are frequently subjected to dust testing. Dust can enter enclosures through openings such as fans and vents. As a result, dust can accumulate inside the device, causing product longevity and safety issues, and in the worst-case scenario, dust explosions. Military products, as well as mining and construction equipment, necessitate dust testing.

Ratings for Ingress by Water

• IPX0: The item is completely unprotected against ingress water.
IPX1: The item is protected from vertically falling water droplets, which means that any droplets that fall on it will not cause damage or disrupt component functionality.
IPX2: This rating improves on IPX1 by providing protection from water droplets falling at an angle of up to 15 degrees from vertical.
IPX3: The item is protected from sprayed water up to a 60-degree angle from vertical impact. The spray can be oscillating with a flow rate that varies depending on the item being tested.
IPX4: This rating adds protection against splashing water from all directions to the IPX3 rating. It is done by exposing something to an oscillating spray for at least 10 minutes. When there is limited ingress and no harmful effects, an item passes.
IPX5: If there is limited ingress with no harmful effects, the item is protected from low-pressure water jets directed from any angle.
IPX6: IPX5 is extended with this rating. In this test, the water pressure can reach 1 bar.
IPX7: This rating goes further than IPX6 and indicates protection from temporary immersion in water. The rating is given after immersing an item in 1 meter of water for 30 minutes with no harmful effects.
IPX8: This rating extends the IPX7 rating for immersion in water to a greater depth and to longer periods of time. The conditions of the immersion are agreed upon between the manufacturer and the testing facility.

Standard Ratings for Ingress by Dust

• IP5X: (Dust protected) This is tested by inspection to ensure any dust that enters would not interfere with the part’s functionality.
IP6X: (Dust tight) This rating implies there can be no ingress of dust at all.

Test equipment differences

IEC 60529 test standard and GB/T4208 enclosure protection grade (IP code), in fact, there are descriptions for dust protection from number 1 to number 6, but only equipment that performs IP 5X and 6X tests. The reason is that the dust in the standard for 1 and 2 requires that the test must not completely enter the shell, that is, the entire diameter of the sphere must not pass through the shell opening. The characteristic of 3 and 4 is that the tested dust must not enter the shell at all. It can be seen from this that the overall protection level is very low.

Therefore, The environmental testing equipment industry does not manufacture appropriate testing equipment for these four characteristics. The requirements of IP 5X and IP 6X are that a limited amount of dust is allowed to enter under certain prescribed conditions, and no dust is allowed to enter. The dust is very fine, and it is conceivable to prevent it from entering.

In fact, The test dust of the sand and dust test chamber is not only talc, But also Portland cement, olivine or smoke ash, etc. in other standards, and its blowing method can also be continuous and periodic. IP 5X: Can not completely prevent dust from entering, but the amount of dust entering must not affect the normal operation of the equipment, and must not affect safety. IP 6X: No dust enters the test sample.
