5.What are the test methods of LSST-01 Leak and Seal Strength Tester?<\/strong><\/p>\n

\u2460Burst Test<\/p>\n

The burst test is to pressurize the package by feeding air into the package until it is failure. The test measure is the max pressure detected before failure.<\/p>\n

\u2461Creep Test<\/p>\n

The creep test is to pressurize the package by feeding air into the package to specified pressure (is 70% or 80% of pressure for max burst pressure generally or set as per requirement) and maintain the inner pressure for a specific time (15~30s generally). The test measure is pass or failure.<\/p>\n

\u2462Creep to Failure Test<\/p>\n

The creep to failure is similar with creep, but during pressure maintaining the package is failure. The pressure inside is 90% of pressure (or set as per requirement) for max burst pressure generally. The test measure is the time until the package is failure.<\/p>\n
