Coupling Port: The coupling port supplies air pressure to product sealing
fixtures or other external pneumatic components. Generally, the port
labeled “2” on front of Sprint LC is used for coupling air output.

Coupling Pressure: The air pressure supplied to external fixtures.
Coupling pressure must be greater than the test pressure and the same as
the incoming line pressure unless additional pneumatic components are
added.

Coupling Time: A delay timer used to apply a clamp or seal to product
under test before the product is filled with air. Coupling time gives
fixtures enough time to seal product before Sprint LC applies test pressure.

Crack Test: A crack test is set up to measure the pressure at which a
product, like a check valve, opens and allow air to flow through. It is used
with parts that do not open quickly enough to cause a drop in the upstream
pressure. An optional downstream sensor is required to measure a device
that opens very slowly. Crack testing differs from burst testing because the
product does not suddenly drop to zero pressure as in a burst test.

Creep Test: A creep test is a subset of a burst test. There is no test type
listed in Sprint LC as a creep test. To setup a creep test first select the
burst test type. A creep test is setup to verify that a part can withstand a
minimum proof pressure. The minimum burst and maximum burst values
are set to the same pressure. This tells Sprint LC to redefine the pass/fail
criteria. If the ramping pressure during the test reaches this value then the
part is considered good.
