Test methods for sterile medical device packaging
Part 13. Flexible barrier films and composite films
Resistance to slow puncture
1 Scope
This part of YY/T 0681 is suitable for measuring the puncture resistance of the flexible barrier film and the composite film anti-drive probe. This test starts at room temperature.
A biaxial stress is applied to the material at a constant test rate until puncture occurs, and the force, energy, and elongation before perforation are measured.
Note. Appendix A gives the precision and bias of the test methods specified in this section.

3 Terminology
The following terms and definitions apply to this document.
3.1
Elongation
The elastic/plastic deformation of the driving probe when it penetrates the flexible film.
3.2
Puncture resistance
The flexible membrane is capable of withstanding the ability to drive the probe to stretch and/or penetrate.
3.3
Perforation
Formation of visible cracks across the barrier film during piercing.
3.4
Probe penetration depth probepenetration
The moving distance of the probe from contact with the film to the momentary decrease in load when observed on a universal tester recorder.
3.5
Penetrate puncture
The flexible membrane showed brittle elastic failure after being punctured by the driving probe.
4 Significance and application
The puncture resistance of the film is an important end-use property, and sharp-edged products will destroy the integrity of the barrier packaging. This will make gas, odor
And harmful contamination into and out of the package, resulting in product damage and reduced shelf life. The puncture resistance of a material is affected by many factors, such as
Film thickness, modulus of elasticity, penetration rate, temperature, shape and type of probe, etc. Therefore, the penetration of the material can be observed with this method.
The stretch response was quantified. Although a combination of experimental factors can be designed and used to simulate a specific end application,
The recommended conditions of the method should be followed in order to make the materials comparable.

5.2 Pressure sensor.
5.3 Puncture test probe, in accordance with Figure 1. For general applications, a hemispherical probe with a diameter of 3.2mm (biaxial stress) is recommended to make the material
Laboratory results are comparable by standard.
5.4 Specimen holder, conform to Figure 2 or equivalent device. In order to make the results comparable between laboratories, the test diameter of the sample is required to be 35mm
(If using other probes, the ratio of fixture diameter to probe diameter is at least 10. 1).
