Perform Flash Test

Step 1:

Inject 12 to 14 psi (maximum) of air into the closure

using a hand pump (Figure 27). Check pressure after

each 25 pumps.

WARNING: To avoid a potentially hazardous

situation that could result in death or serious

injury, do not exceed 14 psi (100 kpa) gauge

pressure. The closure could burst.

Step 2:

Apply soapy water to the edges of the heat-shrink

tubing and watch closure for signs of leakage

(bubbling of soap).

NOTE: A correctly sealed closure maintains pressure with no leaks.

Step 3:

After the flash test has been performed and the closure sealed correctly, carefully remove the air valve

and allow air to escape.
