1 Scope

This standard contains the laboratory measurement of the heat seal between the thermoplastic surfaces after the formation of the seal in the cooling to ambient temperature before the heat sealing strength (hot strength). This standard is applicable to the ability to automatically heat the sample and quickly determine the strength of the hot seal during the exact time after the end of the sealing period Test instrument. This standard does not include manual procedures for the use of non-instruments such as springs, joysticks, pulleys and weights. Note. The result of manual operation will be affected by the operator's technology. This standard gives two test methods using different thermal adhesive strength test instrument parameters. Note 1. The difference between the two test methods is mainly reflected in two aspects. a) test the sealing sample when the separation rate of the fixture is different; b) drawing test machine generated test Test the cooling curve of the material, or measure the maximum force observed after setting the delay time. Both of these test methods can be used to measure this test Within the scope of the method and within the capabilities of the instrument used. Note 2. Appendix A gives a comparison between the two test methods specified in this standard. Appendix B gives the precision and bias of these two test methods.

3 terminology

The following terms and definitions apply to this document. 3.1 Adhesive damage to adhesivefailure Seal the destruction mode at the original interface between the sealing surfaces. 3.2 Interval width breadth So that the peel force at the seal is the (constant) constant temperature range. 3.3 Melt through burnthrough The formation of molten holes and heat distortion of the heat sealing state or condition. Note. Melt-through instructions for sealing conditions (time or temperature, or both) are too high for acceptable seals. 3.4 Cohesive failure of cohesivefailure Peeling causes one or two pieces of sealing material to break in approximately parallel to the seal, and the seal itself does not break the failure mode. Note. See Figure 1. The definition of the term may be different when the adhesive material is used as an isolation assembly for sealing the system.
