Vacuum box testing is a non-destructive examination used when trying to locate weld seam leaks. A vacuum box and a compressor create a high or low pressure vacuum while a detergent solution is applied to the test area. The detergent bubbles, making leaks visible within the created pressure envelope.

The Vacuum Decay leak testing method detects leaks in nonporous, rigid, or flexible packages nondestructively. The test starts by placing a sample in a closely fitting evacuation test chamber equipped with an external vacuum source.
