When you perform cleanroom testing (performance qualification), particle count is the only test that is not a part of “supporting tests”. You should first decide which “supporting test” will you apply to certify your cleanroom. Even all other tests are “supporting tests” as per ISO 14644-3:2019 Cleanroom Testing standard, there are major supporting tests that you should apply depending on your industry.

The below table shows an example of a cleanroom validation test sequence. Please note, this may not be the same for your industry, and starting with a particle count test for a brand-new cleanroom could be a better option.
