Standard Test Method for Detecting Leaks in Nonporous Packaging or Flexible Barrier Materials by Dye Penetration Ingestion-build-47553 This International Standard is a1. Scope 1. 1 Method A of this 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 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
