When selecting test procedures for sand and dust test chambers, consider:
a) Use of equipment. According to the relevant documents, determine the functions to be realized in the sand or dust environment and storage conditions.
b) Natural exposure.
c) The test data required to judge whether the equipment work meets the requirements.
d) Sequence of procedures. If you want to use the same test piece for both the dust and sand procedures, it is usually more appropriate to first perform the less damaging procedure, that is, first perform the dust reduction, then perform the dust blowing, and finally the sand blowing test.
The difference between the programs is the size and movement type of sand and dust. The content of the sand and dust test box for these test procedures can be tailored to: test temperature, dust composition, test duration and air speed.
