Testing Procedure Tips- Solutions 

• Spread the test fluid from the felt tip pen lightly over an area of approximately 7 cm of the test specimen, noting the time it takes for the continuous film of ink to break into droplets. 

• Breaking of the fluid into droplets in less than 2 seconds indicates a lack of wetting and a lower numbered test fluid should be tried.

• If the fluid remains intact for longer than 2 seconds, a higher numbered test fluid should be tried. 

• The aim is to establish the lowest reading at an optimum dwell time of 2 seconds. 

• Extreme care must be taken to ensure the film surface is not touched or contaminated in the areas in which the tests are to be made.

• We recommend the replacement of the inks regularly if the bottled inks are frequently opened to atmosphere. 

*If bottled inks are exposed to the air on a daily basis: dispose of remaining inks after 3 months.

*If bottled inks are exposed to the air on a weekly basis: dispose of remaining inks after 6 months.
