1 Scope

Test methods YY/T 0681 provisions of this section, the provisions of the flexible plate is disposed within the constraints of internal pressure to test its periphery The minimum bursting strength of a seal.

This test applies only to the periphery of the flexible seal (usually a combination of the bag). Especially for its peelable seal has characterized (by the end Remove the peel after a user contents) packaging.

This method is recommended for users to pay special attention may be required to design and production constraints board fixture. About stress factors and structural design considerations See Informative Annex C.

4 Summary of Test Method

4.1 on a single instrument for the test pressure inside the package is filled until the packing breakage. In most cases rupture occurred in a sealed area or Several. Inflatable and pressure equipment requirements increase to maintain the internal pressure before the seal is broken. In the pressurization process, the packaging should be placed in two Between rigid parallel plates (plate bound), to limit the expansion and deformation of the packaging, but so that the sealing surrounding area unconstrained. An insert inside the package A sensor for detecting the internal pressure of the package rupture. Depending on the application, this test method requires the use of two configurations restricting plate, described as follows.

4.1.1 opening packaging configurations. three for the peripheral seal, the fourth side open packaging. This configuration is commonly used in the production of preformed packaging. Configuration uses described in Figure 1.
