LSST-01 Leak and Seal Strength Tester 

Application
Evaluating the integrity through pressure decay (internal pressurization) leak testing is essential to confirm the sample's ability to deliver the necessary product protection. Seal integrity tests are conducted to evaluate options for sustainable packaging, cost-effective packaging solutions, and potential fluctuations in sealing parameters along the production line. Ensuring the consistency and reliability of package seals remains of great importance for upholding product quality and safety standards.

Test Method
Pressure decay is a highly prevalent technique for conducting leak testing. This method involves monitoring the reduction in pressure within the sample. Initially, the sample is pressurized to a specified target level, after which the air source is sealed. Subsequently, any decrease in pressure is detected and serves as an indicator of a potential leak. The analysis of sample performance can be approached in three ways: burst testing, creep testing, and creep-to-failure testing.
