small rigid products, and 5.0 sccm or greater for larger and more
flexible products.
If the acceptable leak rate is relatively small (less than the rates
discussed above) a pressure decay test is probably your best
choice for leak testing. Call Uson to discuss your special testing
needs. We specialize in helping test engineers come up with the
very best tests for a wide range of products.
When setting the maximum flow setpoint, you’ll need to
experiment to find the best setting. The maximum flow setting is
typically quite high above zero to allow for high speed testing-the
reason to use a flow leak test in the first place. If the maximum
flow setting is set too close to zero and the time is kept short, a
high number of rejects could occur simply due to inconsistencies
among the products tested. Atmospheric and room pressure
changes could also cause errors if the maximum setpoint is set too
close to zero.
In a leak test using flow, you have the option of using fill time or
going straight to test phase. Fill time is usually needed for large
parts that need to fill with air before they start flowing. Small
parts can often do without fill time because they fill up and start
flowing immediately. The flow rate is displayed for both during
the fill and test phases.
Protect the Flow Sensor
Do NOT run a flow test unless product is attached to Sprint iQ's test port.
Without this restriction, the high flow rate could damage the flow sensor.
