Reagents and Materials 7. Sampling, Test Specimens, and Test Units 8. No single procedure can be given for all situations.

Therefore, Practice D should be used as a guide in planning sampling procedures. It is important that the test specimens are cut with clean, uniform edges so as not to affect the test results.

It may be desirable to test specimens in the transverse cross-machine direction for special purposes. Preparation of Apparatus and Calibration 9. A few trial runs may be required.

Conditioning Example: Boil- able pouch applications. NOTE 2—At these conditions pouch and contents should be aged to allow time for contents to migrate into seal area. Procedure That is, crinkle roughly or apply adhesive tape to both sides, or both, and pull apart. If not, initiate the separation by making a heat seal and pulling it apart. If both the above fail, determine which solvent seems best by trial and error and initiate the separation by immersion of the end of the strip in the solvent for as little time as possible to initiate the separation.

Heat the solvent solution only if absolutely necessary. Dry well in room air without heat. Repeat for each test specimen in the test unit. Calculation of Results

Their performance is often dependent on the ability of the laminate to function as a single unit. If the plies have not been properly bonded together, the performance may be adversely affected. Laminates may maintain adequate bond strength under standard test conditions, but under conditions of use may exhibit an increase or decrease in bond strength. Applying heat, such as in boilable pouch applications, may adversely affect bond strength, as may cold temperatures, such as those encountered in freezer storage of foods. Fats and oils may also influence bond strength as well as the softness or moduli of the plies. This test method can be used to compare bond strength of similar materials and to study changes under these and other conditions of end use, providing caution is used with respect to the effects of the included force to bend the separated plies. Scope 1.
