Ingress protection testing is performed to check for a product’s ability to resist the infiltration of water, dust, and other foreign solids to ensure functionality, safety, and product compliance.
Ingress protection testing is performed to check for a product’s ability to resist the infiltration of water, dust, and other foreign solids to ensure functionality, safety, and product compliance. It is part of waterproofness testing. The IP testing plays a critical role in safeguarding the product. Obtaining the appropriate IP rating for products is essential in various industries, from consumer electronics, automobiles, and avionics to wires and cables. IP rating varies over a range of degrees of protection from liquids or solids or both depending on the industrial standard, the product tested, and marketing requirements.
Rating is designated with IP followed by two numbers. The first number stands for protection against solids, and the second for liquids. For example, IP67 denotes the product is rated with full protection against solid objects like dust and sand, and it has been tested to work for at least 30 minutes while under 15cm to 1m of water. Most testing is performed to test the product’s fittings and joints, hermetic seals, open ports, coatings, shields, gaskets, etc. Waterproofness testing is performed to check components against water jets, continuous streams, drip, sprays, and immersion for s specific time, pressure, and temperature testing. Dust and sand testing is also performed as part of IP rating tests.
Using a calibrated IP testing apparatus, it is possible to determine a product’s sensitivity to solid particle infiltration. Fingers and other tangible things are examples of solid alien objects. Testing with dust and sand is a further option.
IP testing facilities will employ calibrated pieces of a specific size to evaluate larger solid objects. To check if a case has apertures that permit penetration, these tools are also known as accessibility probes.
The test object is put in a dust chamber for the dust test. The dust is a calibrated substance that has been stirred up in the chamber such that it is suspended and covers the test object. The enclosure’s outside is carefully cleaned after the testing for dust intrusion is finished. The cage is then opened to assess the level of dust present.
RTCA-DO-160 Section 12.0 is one of the more well-liked sand and dust military standards.
There are various ways to determine whether a case is a watertight enclosure. Testing for waterproofness may involve liquids of different densities, quantities, and test intervals. Items may be tested using dripping water. They may also be put through water-spraying or rain-driving tests. A fire hose or a garden hose can be used for the driving rain or water jet test.
Ingress protection IP testing includes immersion testing as well. Water is used to submerge the test object. International guidelines specify the duration of exposure and depth of submersion. To comply with the requirements of the IP test standard, many items must be immersion-proof.
It is also possible to condition liquids for IP testing. Items that are being shipped may need to undergo cold water testing. Moreover, the liquids might corrode. For instance, we have finished several ocean simulations. To replicate ocean conditions, products were submerged in cold, salt water. Few IP Code laboratories are capable of performing this testing.
Infinita Lab offers water and dust tests on a variety of products for the IEC 60529 standard. Customer-specific test plans can be defined to include IP testing. The testing process is a 2-step procedure. The first step is the exposure of the device to either solids/dust or water, using a standardized protocol. The second step is the functional test. The latter can either be an optical inspection or a more dedicated functional test, either performed at our IP test facility or at the customer site. IP stands for “ingress protection,” and it is a well-recognized norm. The International Electrotechnical Commission’s IEC 60529, the International Organization for Standardization’s ISO 20653:2013, and other standards use it.
The overall environmental IP standard for permanently fixed, non-portable electrical equipment, including lights, is IEC 60529 (Degree of Protection Provided by Enclosures). The purpose of IEC 60529 is to rate and grade electric and electronic device enclosures based on how well they resist dust and liquids and how simple it is to reach any potentially dangerous components of the enclosure.
IPX denotes a classification standard that evaluates how resistant an item is against water. Following are some of the important ratings for Ingress by water
IEC 60529 / EN 60529 is one of the most widely used enclosure testing standards. Another well-liked ingress protection standard is NEMA 250. IEC 60598 and ISO 20653 are two other popular standards. This is a cross-reference table showing how NEMA and IP Codes relate to one another.
Many military enclosure standards exist as well. These standards include MIL-STD-810, 202, 750, and 883. There is a waterproofness component in RTCA-DO-160 as well. The military places a lot of importance on the level of protection. To improve product marketability, IP ratings for retailers may also refer to military standards.
To sum up, testing for Ingress Protection (IP) is an essential component in guaranteeing the robustness and dependability of electronic equipment in diverse settings. As technology develops and gadgets become more and more ingrained in our daily lives, it is crucial to protect them from the elements, including water and dust. IP testing offers a methodical way to assess a product’s resistance to these factors. It is regulated by standards like IEC 60529.
IP testing offers important insights into a device’s performance capabilities through the methodical process of exposing it to solids/dust or water, followed by functional tests. This two-step process ensures that the device continues to function as intended even after it has been exposed to difficult circumstances by evaluating both the functional and physical obstacles. Additionally, because IP testing is flexible, test plans may be customized for each customer, allowing assessments to be tailored to the particular needs of various goods. The fact that Infinia Lab is dedicated to providing IP testing services only serves to highlight how crucial this procedure is in the cutthroat market of today.
