IEC60529 Stainless Steel Sand and Dust Test Chamber
1.1 Dust-proof test box is designed and manufactured according to
GB4208-93 (equivalent to IEC60529-2001) "Shell Protection Grade (IP
Code)" and is suitable for sand and dust test of electrical
products with the first characteristic digits of 5 and 6 (IPX5 and
1.2 The test chamber can provide non-laminar vertical circulating
airflow of dust, which can be controlled regularly. It is equipped
with a vacuum pump to pump air into the outer shell of the tested
product, and it can adjust the pumping volume and pressure
difference.In addition,the air temperature control device is
installed in the chamber to ensure that the test is carried out
under the standard environmental conditions.
1.3 According to the standard requirements, this test chamber
adopts the artificial analogy dust environment to test the
dust-proof ability of the tested products, and its specific
requirements and eligibility criteria should be in accordance with
GB4208-93 (IEC60529-2001) or product-related standards.
