The concentration of IPA in the Test Solvent will influence the test results. The Test Solventshould be 75 % IPA, +/- 3%. Because IPA will evaporate quicker than H2O, the concentrationof IPA will tend to decrease with time. This concentration should be checked, and if necessaryadjusted, periodically. Non-ionic contaminates such…
