Helium Leak Test Walkthrough: Setup, Soak, Acceptance

%s

Leak testing is only meaningful when the test conditions and the acceptance criterion are agreed before the part is built. This walkthrough shows the preparation, the sealing of ports, the instrument set-up and the record that is issued with the assembly.

We state the criterion as a project-specific value rather than quoting a universal number on a public page; the applicable limit belongs in the purchase specification. The written procedure is available now, with footage to follow.

Key Points

• Port sealing and assembly preparation prior to the test.
• Stabilisation before reading, and what gets written into the test record.
• How the acceptance criterion is set per project rather than assumed.

This page publishes the written procedure and acceptance points. Filmed footage is in production; no player is embedded until a reviewed clip exists.
