is the Standard Test Method for Determination of Leaks in Flexible Packaging by Bubble Emission. It is a whole-package test method, meaning it tests the entire seal integrity of a pouch or bag rather than just a specific seal area.

No. For rigid containers, refer to (vacuum testing of rigid containers) or ASTM D3079 (dry testing). D3078-21 explicitly covers flexible and semi-rigid pouches.
