When the IEC60529 dust test chamber is conducting dust tests, the type of dust used needs to meet certain standards and requirements. According to relevant information, the following is the relevant content about the use of dust in the IEC60529 dust test chamber:
Dust type: The dust used in the dust test chamber mainly includes inorganic dust, organic dust and mixed dust. Inorganic dust includes mineral dust, metallic dust and artificial inorganic dust; organic dust includes animal dust, plant dust and artificial organic dust; mixed dust is a mixture of the above two types of dust2.
Dust requirements: The test dust is dry, non-abrasive fine dust that can pass through a flat mesh sieve with a mesh size of 75μm and a wire diameter of 50μm. The test dust should not be used more than 20 times. It should be kept dry to maintain the fineness of the dust and should be dried at 80℃ for 2h before use.
Use of talcum powder: The dust used in the dustproof test chamber is fine talcum powder, which is also filtered through a metal square hole sieve with a wire diameter of 50μm and a sieve hole size of 75μm. The amount of talcum powder is 2kg per cubic meter of the test chamber volume, and the number of uses shall not exceed 20 times.
In summary, when conducting the IEC60529 dustproof test, talcum powder or other suitable dust types that meet the standards should be selected, and the relevant use and handling requirements should be strictly followed.
