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).
1.1.1 The ability to visually detect channel defects in package seals is highly dependent on the size of channel, the degree of contrast from sealed and unsealed areas, the amount and type of adhesive between the two package layers, reflecting light angle, types of material used, the use of magnification, and the inspector's level of training and experience.
