3. When you hear the pump reverse direction, have an assistant mark the spot on
the test strip and indicate whether the pump was at the top “T” or the bottom “B”
of the stroke.

4. Continue spraying for four or five complete pump cycles with an assistant
marking the test strip every time the pump gets to the top or bottom of the stroke.
Your completed test strip should look something like figure 3 (above).
5. Use a tongue depressor to test several areas on the strip: top of stroke, bottom of
stroke, and the up- and down-stroke in several places. Repeat testing for
material hardening several times to find out if some areas are hardening faster or
slower than other areas.
Note: Color-reactive materials (materials that change color when they harden)
make this testing very easy and accurate. Magnum Venus Plastech recommends
using color-reactive materials whenever possible.
6. Make written notes directly on the test strip to show what happened. Pay
particular attention to areas that harden faster or slower than other areas
because that indicates a problem.
