1.1 This test method covers the determination of channels in the package seal down to a width of 75 μm [0.003 in.] with a 60–100 % probability (see Section 8).
1.2 This test method is applicable to packages with at least one transparent side so that the seal area may be clearly viewed.
1.3 The 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.
