Standard Test Method for Detecting Leaks in Nonporous Packaging or Flexible Barrier Materials by Dye Penetration

Importancia y uso:

4.1 Contaminants may enter the package through leaks. Alternatively, product may be lost from the package through leaks. These leaks are frequently found at seals between package components of the same or dissimilar materials.

4.2 Ingress or egress of gas or moisture through leaks in a package can also degrade sensitive contents.

4.3 There is no general agreement concerning the level of leakage that is likely to be deleterious to a particular package. However, since these tests are designed to detect leakage, components that exhibit any indication of leakage may be rejected.

4.4 These procedures are suitable for use to verify and locate leakage sites. They are not quantitative. No indication of leak size can be inferred from the test. Therefore, this method is employed as a go/no-go test.

4.5 These tests are destructive. No package or component test samples exposed to dye penetration testing may be used for final product packaging.
