Abort a test, how to: Press the red STOP button during the
test. An aborted test will register on the Tested and Rejects
counters.
Atmosphere (1): In this guide, atmosphere means room air
pressure. Atmospheric pressure is nearly synonymous
with barometric pressure-an external force pushing on all
sides of every object on earth’s surface. During a flow test,
product being tested must flow into atmosphere, which
causes a resistance to flow called backpressure. Room
atmosphere can change due to fluctuations in air
conditioning or changing weather conditions.
Atmosphere (2): The word atmosphere can refer to a unit of
measure equal to pressure at average sea level. By
convention, one atmosphere equals 14.7 psi. To say a test
was taken at one atmosphere means the test was made at
(or converted to) average sea level.
Barometric Pressure: Also called atmospheric pressure. The
force of air pressing down on the earth. Barometric
pressure changes with elevation and weather conditions.
Sprint’s regulator compensates for changes in barometric
pressure to provide a constant relative output.
Bulkhead Fitting: A connection passing through a panel or
enclosure. Standard bulkheads on the front have a #10 by
32 pitch machine thread.
Burst Test: One of Sprint iQ’s possible operating modes in
addition to pressure decay and flow. A burst test slowly
fills a product through a flow valve set by users. After the
burst, pressure rapidly drops to near zero. Sprint iQ
captures the pressure immediately before the product
ruptures or in some way opens to atmosphere. Burst mode
is useful for testing pop-off valves, package seals, or
