4.1.1.4 Timers in Decay Tests
Couple Time
Couple time is used as a delay causing Sprint iQ to wait for a
preset period after start is activated and before Sprint iQ supplies
air to the part to be tested. Couple time can be used in either a
manual or automated operation.
If coupling valves are used, the valves turn on at the start of the
test and turn off when the test is finished.
Couple time is generally the period in which the pneumatic or
mechanical fixtures are applied to seal the product from
atmosphere. Often used in open-ended products such as tubing,
catheters, and containers.
If external fixtures are not used, set the couple time to zero time
(off).
Fill Time
At the start of fill time, a valve opens to pressurize the product.
Fill duration depends on the size and construction of the part to be
tested. Optimum fill time pressurizes the part fast enough for a
good throughput, yet not so fast that the product is still expanding
during test phase. Large products require a longer fill time than
smaller products. At the end of fill time, Sprint iQ closes the
supply air valve and pressure is trapped inside both the part and
Sprint iQ’s test circuit.
In a test using vacuum, fill time is actually evacuation (evac) time.
Stab Time
This time is provided to let pressure settle before going into the
test phase. Best established through trial and error, stabilization
time varies depending on product characteristics. Start with
stabilize and test times that are equal to each other. The Stabilize
time is used to get the maximum separation and repeatability in
