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
coupling 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.
Parameters to be set in a burst test—
• Test Pressure
• Coupling Time
• Test Time
• Dump (Auto, Off or time)
• Max Burst (maximum burst level)
• Min Burst (minimum burst level)
• Burst Event (amount of pressure drop to be detected)
• Next Program
Min and Max Burst
Minimum and maximum burst setpoints establish a window in which a
burst event must take place to be a pass. If the burst occurs below the
minimum setpoint, the test is stopped and LOW appears in the status box
on the run display. The fail light turns on. Figure 62.
If pressure goes above the maximum setpoint without the product
bursting, Sprint LC stops the test and shows HIGH in the status box on
the run display. Figure 67. The fail light turns on.
If product fails to reach a peak pressure above the maximum burst
setpoints before the end of the test phase, Sprint LC stops the test and
shows NO in the status box on the run display.
