Cleaning Efficacy: Soil Test

HTM, WHTM and SDCEP requires that this test is carried out quarterly and annually.

What is it?

This is a test that ensures that the cycle is able to adequately clean a heavily soiled load. A strip coated with an artificial test soil represents a difficult cleaning challenge which the cycle must remove to pass the test.

It is important to use the correct test soil for your machine as recommended by the manufacturer. Using the wrong test soil may provide misleading results.

When is it Perfomed?

HTM, WHTM and SDCEP requires that this test is carried out quarterly and annually. The frequency of User tests in addition to the quarterlyand annual requirement is dictated by the manufacturer and ranges from weekly to monthly.

What Equipment and Materials are Required?

  • Ultrasonic Cleaner Log Book.
  • Test Soil Specific to the Machine Under Test.
