1.Scope 1.1This test method defines a procedure that will detect and locate a leak equal to or greater than a channel formed by a 50 m [0.002 in.] wire in a the edge seals of a nonporous package. A dye penetrant solution is applied locally to the seal edge to be tested for leaks. After contact with the dye penetrant for a minimum specified time, the package is visually inspected for dye penetration or, preferably, the seal edge is placed against an absorbent surface and the surface inspected for staining from the dye. 1.3This test method is used for both transparent and opaque nonporous surfaces. 1.4This test method requires that the dye penetrant have good contrast to the materials being tested and/or the absorbent surface. 1.5The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.6This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
This approach is commonly used by users of packaging materials to test package integrity. However, no standardized method currently exists for nonporous packages and packaging materials
