Good working performance.

Iii. Standards Implemented by this equipment:
La and Lb in GB2423.37-89; GB 4208-98; IEC60529.
The test chamber is manufactured in accordance with the following standard requirements
The dust-proof test chamber is designed and manufactured in accordance with GB4208-93(equivalent to IEC60529-2001) "Enclosure Protection Class (IP Code)", and is suitable for conducting sand and dust tests on electrical products with the first characteristic digit being 5 and 6(IPX5 and IPX6).
This test chamber, in accordance with the standard requirements, uses artificial simulation of a dust environment to test the dust-proof capability of the tested items. The specific requirements and qualification determination standards should comply with GB4208-93(IEC60529-2001) or the relevant standards of the product.
Note: This test chamber can meet the requirements of GB2423, GB4706, GB4208, DIN for household appliances, low-voltage electrical appliances, automotive and motorcycle parts
Test requirements for shell protection grade. This device cannot meet the requirements of the sand and dust test with air source as stipulated in GJB150.
