Testing intended to assess a package without damaging the package or its contents.
Also called: nondestructive testing; non-destructive leak testing.
Does nondestructive mean every defect is detected?
No. Nondestructive describes the intended effect on the sample, not detection of every defect. Package construction and fixtures still affect capability, and expansion may need to be restrained during testing. Sample effect and defect sensitivity are separate attributes.
Ask for evidence of both: relevant defect detection and an assessment that the proposed pressure, restraint and contact do not unacceptably change the actual package/product. A technology label alone cannot establish either outcome for every film, foil or pocket geometry.
That is a separate disposition decision. A method intended not to damage a sample may permit useful repeat measurements, but repeatability is not automatic permission to return tested units to sale. Keep test exposure, sample handling and the site’s approved disposition requirements distinct from the instrument’s description.
Dye exposure and opening change the sample, whereas a suitable nondestructive method may allow repeat measurements. Specify whether testing serves development, routine sampling or inline inspection, since each involves different handling and disposition needs.
