Auto Parts Test Equipment ISO 20653 Test Chamber For Protection Against Dust

Standard:

ISO16750-4 Road vehicles-Environmental conditions and testing for electrical and electronic equipment-Part 4: Climatic loads clause 5.10 dust test;

ISO 20653-2013 Road vehicles — Degrees of protection (IP code) — Protection of electrical equipment against foreign objects, water and access, figure 1- Principle test set-up for determining the protection against dust in vertical orientation; degree of protection against foreign objects 5K and 6K;

Purpose:

This test simulates a dust pumping effect caused by temperature changes inside the housing of the DUT, due to intermittent electrical operation. Failure mode is electrical or mechanical malfunction caused by dust, e.g. on the surface of electrical contacts. The application of this test shall be stated in the specification of the DUT.

Application:

The sand and dust test chamber is used to test the sealing performance of the product shell. It is mainly used for the test of IP5X and IP6X for enclosure protection grade. By simulating the sand and dust weather, to test the outdoor lamps, auto parts and other products.

Test method:

Perform the test as specified in ISO 20653, using the variant described below.

As an alternative to the Arizona A2 test dust (i.e. test dust A2 in accordance with ISO 12103-1) that is specified in the ISO 20653 test method, the following test dust mixture may be used:

⎯ 50 % by weight of limestone (with clay and sand), i.e. “unbaked Portland cement”, and

⎯ 50 % fly ash with the following grain size distribution (in accordance with IEC 60068-2-68):

⎯ 33 % by weight ≤ 32 µm;

⎯ 67 % by weight > 32 µm, but ≤ 250 µm.

The test should be carried out oriented as mounted in the vehicle.

The test will consist of 20 cycles, each one as defined in Figure 9.

The cycle time and time of operating mode 3.2 shall be agreed between customer and supplier.
