Experimental methods and precautions of IP protection class test tools
IP65 test method: IP6X stands for dust tightness test, which completely prevents dust from entering. It is placed in a sand dust box and needs to be pumped under negative pressure. The test time is 8 hours; ipX5 water spray test, the product sprays water on each surface, and the product does not When water droplets enter, use a nozzle with a diameter of 6.3 mm to be 2.5-3 meters away from the sample and spray water on each surface for at least 3 minutes.
IP66 test method: IP6X stands for dust tightness test, which completely prevents dust from entering. It is placed in a sand dust box and needs to be pumped under negative pressure. The test time is 8 hours; ipX6 is a strong water spray test. Strong spray test on the surface, no water droplets enter the product, use a nozzle with a diameter of 12.5mm to be 2.5-3 meters away from the sample, and spray water on each surface for at least 3 minutes.
IP67 test method: IP6X stands for dust-tightness test, which completely prevents dust from entering. It is placed in a dust box and needs to be pumped under negative pressure. The test time is 8 hours; ipX7 is a short-term immersion test, using a diving box with the water surface on the top of the shell. The above is at least 0.15 meters, the bottom surface of the enclosure is at least 1 meter underwater, and the test time is 30 minutes.
IP68 level test method: IP6X stands for dust-tightness test, which completely prevents dust from entering. It is placed in a dust box and needs to be pumped under negative pressure. The test time is 8 hours; ipX8 is immersed in a submersible test, using a diving tank, and the water surface height and test time are up to the user In consultation with the manufacturer, it is an open level.
Precautions for the use of IP protection test tools:
1. The instrument must be checked before operation to confirm that it is normal before it can be used.
2. The internal metal of the tested product must be connected to each other with wires and then the test clip should be connected;
3. Install on a supporting surface or similar device when testing the product;
4. The instrument is afraid of humidity and heat, so pay attention to moisture and high temperature;
5. If an abnormality is found in the use process, the equipment shall be immediately marked to be disabled, and the technical department shall be notified for maintenance, and the same batch of products when the instrument is abnormal shall be tested again before it can flow into the next process;
6. Pay attention to the maintenance of the instrument. The operator must disconnect the instrument power when leaving the post.
