Title
Standard Test Method for Detecting Seal Leaks in Porous Medical Packaging by Dye Penetration
ASTM International
Publication Date:
Nov 10, 1998
Scope:
This test method defines materials and a procedure that will detect
and locate a leak equal or
greater than a channel formed by a 50 µm (0.002 in.) wire in
package edge seals formed
between a transparent film and a porous sheet material. A dye
penetrant solution is applied locally
to the seal edge to be tested for leaks. After contact with the dye
penetrant for a specified time,
the package is visually inspected for dye penetration.
This test method is intended for use on packages with edge seals
formed between a transparent film
and a porous sheet material. This test method is limited to porous
materials which can retain the
dye penetrant solution and prevent it from discoloring the entire seal
area for a minimum of 20 s.
Uncoated papers are especially susceptible to leakage and must be
evaluated carefully fro use with
this test method.
This test method requires that the dye penetrant have good contrast to
the opaque packaging
material.
The values stated in SI units are to be regarded as the standard. The
values given in parentheses
are for information only.
This 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.
