IP test equipment namely ingress protection test equipment is a used to test the product shell protection level. LIB IP test equipment is a specially designed test equipment to determine the protection of the product against the invasion of solid objects (such as dust, sand, etc.) and liquids (such as water).
IP test equipment is widely used in many fields such as electronics, electrical, communication, automotive, aerospace, industrial manufacturing and so on. Through the IP level test, it can ensure that the product can still operate normally in a variety of harsh environments, and improve the reliability and security of the product.
For example, for electronic equipment used outdoors, such as street lights, surveillance cameras, etc., it is necessary to have good waterproof and dustproof performance to prevent failure due to environmental factors. The IP test equipment accurately assesses whether these products meet IEC 60529 and other appropriate standards.
How to Maintain and Calibrate the IP Test Equipment?
1. Daily cleaning
1) After each use, the water stains, dust and debris inside the test chamber should be cleaned.
2) Clean the water tank regularly to remove dirt and sediment to ensure clean water quality and prevent nozzle blockage.
3) Clean sprinkler heads and spray pipes to ensure smooth water flow. For clogged nozzle, you can use a soft needle or toothpick to unclog.
2. Check components
1) Check the door seal gaskets of the test chamber weekly for damage, aging, or deformation. If there is any problem, it should be replaced in time to ensure the tightness of the test chamber.
2) Check electrical connections for looseness, damage, or aging. Ensure that the wiring is firmly connected and there is no risk of short circuit.
3) Regularly check the operation of power components such as pumps and fans, and observe whether there is abnormal noise, vibration or overheating. If there is any abnormality, it should be repaired or replaced in time.
3. Regular maintenance
1) Add appropriate amount of lubricating oil to the mechanical moving parts of the test box every month, such as guide rails, lead screws, etc., to reduce wear and ensure smooth movement.
2) Check and calibrate the control system of the test chamber every quarter to ensure that the parameters are set correctly and the sensor works normally.
3) Perform a comprehensive maintenance of the test chamber once a year, including checking the refrigeration system (if applicable), heating system, air duct, etc., and cleaning up accumulated dust and debris.
4. Water quality management
1) Clean water should be used in the rain test chamber to prevent pipe blockage.
2) For the test chamber that is not used for a long time, the water in the tank should be emptied to prevent the growth of bacteria and algae.
5. Storage precautions
1) If the test chamber is not used for a long time, it should be placed in a dry and well-ventilated environment and covered with a dust cover to prevent dust from entering.
2) Before storage, ensure that the inside of the test chamber is clean and all components are in normal condition.
6. Calibration and verification
1) In accordance with the specified time interval (usually one year), ask professionals to calibrate and verify the performance indicators of the test chamber to ensure that it meets the relevant standards and test requirements.
2) Calibration and verification include temperature, humidity, spray pressure, flow and other parameters.
What Is the Structure and Composition of the IP Test Equipment?
1. Shell material: usually stainless steel, with good corrosion resistance and strength, the design of the shell is usually in line with international standards to ensure the long-term stable operation of the test chamber and good sealing of the studio.
2. Water tank: used to store test water, equipped with water level monitoring and automatic refill device to ensure sufficient water during the test.
3. Sprinkler head: according to different waterproof test levels, equipped with different types and specifications of sprinkler heads, such as pendulum nozzle, high pressure water nozzle, etc. A rotating turntable is placed in the working room, and water can be evenly sprayed on the surface of the test piece. The waterproof power connector in the work room energizes the test piece and restores the most realistic test conditions.
4. Air duct: used to generate uniform air flow to ensure the uniform distribution of dust particles in the test chamber. Vertical circulation air blows dust to the studio, forming a dust circulation system.
5. Control system: IP test chamber is equipped with advanced control system, which can realize accurate control and adjustment of parameters such as temperature, water output and dust output in the test chamber. The control system can also realize the setting and automatic control of various test modes.
LIB Industry IP Test Equipment Case
In January 2019, South Korean testing agency Standard Bank sent an email to LIB:
1. Dust chamber DI-1000 or DI-2000;
2. IPX1X2 R12-1600, IPX3X4 R-3200, IPX5X6 Chamber, IPX7,8 Chamber
3. Salt spray test chamber
According to Standard Bank’s needs, LIB customized an IP system, including from IPX1 to IPX8 tests, and IP5X/6X tests. We have helped Standard Bank perform ISO17025 calibration of the flow sensor of IP water test equipment every year to achieve more accurate tests.
