LISUN JL-12 IP Waterproof Test Equipments – After-sales Frequently Asked Questions (FAQ)

JL-X waterproof test machine is according to IEC60529:1989 +A1:1999 +A2：2013 《Degrees of protection provided by enclosures(IP Code)》, IEC60598, IEC60335 and IEC 60034-5, GB/T-2423.2, GB4208, GB7000.1. The JL-X includes the following test grades: IPX1, IPX2, IPX3, IPX4, IPX5, IPX6, IPX7 and IPX8 (Refer to page 51 of IEC60529). It is widely used in the authentication test organization for the products such as electrical & electronic products, LED luminaires as well as in the relevant quality control department for the waterproof detection of the enclosures protection grades.

Q1: Why need an air compressor?
A1: The air compressor is an auxiliary device and is not required during the test. After the test, the air compressor is used to quickly clear all the water in the dripping board. Therefore, if there is no air compressor, the test can be carried out normally no problem.
Note: If you need to use an air compressor, please remove a few needles from the dripping board first, and then start the air compressor. This is to avoid the danger of the needle loosening due to excessive air pressure in the dripping board.

Q2: How to avoid sample power cord entanglement?
A2: During the test, the turntable needs to rotate. The turntable we designed only rotates in one direction if the sample does not need to be powered during the test; if the sample needs to be powered during the test, the turntable will automatically change its direction every minute to avoid the sample power cord from getting tangled.

Q3: How to confirm test results?
A3: If the sample short-circuits and shuts down during the test, it is definitely not in compliance with the standard. If the sample can still operate normally with power, you need to take out the sample, wipe off the moisture on the surface, and then open the sample to check whether there is water inside. If there is water, it is also not in compliance with the standard.
For specific details, different industries have different rules, and you can refer to the corresponding industry standards.

Q4: The drip board is still dripping after the test
A4: After the test is stopped, the turntable stops rotating and the water inflow stops automatically, but there must be some water in the dripping board. You can manually remove the sample.

Q5: Needle blocked
A5: Before use, clean the inside of the dripping board, water pipes, etc. to prevent debris from clogging the needle during testing. After the equipment has been used for a long time, if the filter element changes color, please replace the filter element in time. If the needle is clogged, it does not need to be thrown away. You can use the needle tool provided by LISUN to dredge the needle and then reinstall it for continued use.

Q6: How to convert water flow and rainfall?
A6: The conversion formula between water flow and rainfall is: water flow (L/min) = rainfall (mm/min) * rainfall area (m²) * 0.001 (because 1 cubic meter = 1000 liters, 1 millimeter = 0.001 meter).
