Sand and dust schematic
This equipment implements standards
La and Lb in GB2423.37-89; GB 4208-98; IEC60529. The test box is made according to the following standard requirements
The SC series dustproof test box is designed and manufactured in accordance with GB4208-93 (equivalent to IEC60529-2001) "Enclosure Protection Level (IP Code)". It is suitable for electrical products to carry out the first characteristic numbers of 5 and 6 (IPX5 and IPX6). ) Sand and dust test.
In accordance with the requirements of the standard, this test box uses an artificially simulated dust environment to inspect the dust-proof ability of the tested product. Its specific requirements and qualification criteria should be in accordance with GB4208-93 (IEC60529-2001) or product-related standard requirements.
Another note: This test box can meet the requirements of GB2423, GB4706, GB4208, DIN, household appliances, low-voltage electrical appliances, automobile, motorcycle parts shell protection level test requirements. This device cannot meet the sand dust test with wind source in GJB150.
