A burst test is built around two test conditions:
1. Peak Pressure (P)
Peak Pressure is a constantly updated value before the burst. Sprint iQ
uses the peak pressure reading as the starting point to measure the event
value. After the event the final peak value is compared to the minimum
and maximum burst setpoints to decide whether the product is accepted
or rejected.
2. Event
(E)
Event is the amount of pressure drop from the peak pressure. When a
burst occurs product opens to atmosphere and the pressure begins to rap-
idly drop to zero pressure.
Event Value (End of Test Trigger)
Event value is a setpoint entered in the parameters menu. Event
value is the peak pressure minus the event pressure. In other
words, how much the pressure drop is needed from a peak
pressure to be considered a real burst. For example, an event value
setting of 0.2 psig means the product must drop at least 0.2 psig
below the peak pressure to trigger an end of test and a pass/fail
decision.
Parameters in a Burst Test
Burst testing uses some of the same parameters used in pressure
decay and flow testing, with three major differences:
1. A burst test has only couple and test timers.
2. Pressure error is not used in a burst test.
3. A burst test uses a trigger or threshold setting called an
event value, which is a drop in pressure from a peak
pressure reading immediately before the product opens to
atmosphere.
