Programming a Burst Test
Follow these steps to program a burst test.
Note: This procedure also applies to creep testing.
1. Turn the LOCKOUT keyswitch to program mode. Test Parameters
is highlighted on the setup menu. Press the ENTER/BACK keypad.
Use the INCREMENT and DECREMENT keypads to select the program
number under edit.
2. Press NEXT to highlight Test Type. Use INCREMENT to select Burst.
3. Press the NEXT keypad to highlight Test Pressure. Block the test
port with a leak-tight cap, then press the INCREMENT keypad once.
Now use the pressure regulator knob to adjust the test pressure
reading. When the reading is set, push the ENTER/BACK keypad.
This action sets the maximum test pressure possible after ramping,
even if a burst does not occur. The highlight bar moves down to
the next parameter. Read page 37 - 39 for more information about
setting the test pressure.
4. Press the NEXT keypad to highlight Coupling. Use the GoTo keypad
to enter the pop-up menu and set the values for coupling time. If
external fixtures connected to the coupling port are not in use, set
the coupling time to zero seconds and the setting to OFF. Press the
BACK keypad to exit.
5. Press the NEXT keypad to highlight Test Params. Use the GoTo
keypad to enter the sub-parameter pop-up menu. Fill Time will be
highlighted. Use the INCREMENT and DECREMENT keypads to set the
value for the maximum test time. Test time is when Sprint LC
takes readings to look for peak pressure burst and event. If there is
no burst within this time, the tester will stop and fail the part as a
no burst.
6. Press the NEXT keypad to highlight Dump. Dump can be set to
Auto, Off, or a set time. This opens the dump valve to atmosphere
to vent the product between tests. In most burst tests, the product
itself is vented to atmosphere upon rupture, often making Dump
unnecessary and can be set to Off. However, if creep testing and
pressure remains trapped within the part at the end of the test, then
dump can be set to Auto or a time. Dump is also valuable to
