Recommended Test Procedure

As a suggestion, if the chemical you are interested in is not listed in the table, or is labeled “TR” (Test Recommended), you may conduct your own test by following these procedures:

  1. Immerse the filter cartridge in the test solution at the desired operating temperature for a minimum period of 48 hours.
  2. Thoroughly examine the filter cartridge for any change in colour, swelling, softening, deformation, weakness or any other changes.
  3. Observe the solution to see if any changes in colour, clarity, viscosity, etc. have taken place.
  4. If possible, analyze the solution to check if any chemical reaction has taken place.

If there is no perceptible change in the solution or the cartridge, it may be considered suitable for use.
