ASTM F1886/F1886M-2016 "Standard Test Method for Determining the Integrity of Soft Encasement seals by Visual Inspection" is designed to evaluate the sealing performance of Encasement seals by visual inspection. This method can help identify channel defects in seals that may result in decreased Encasement integrity and product protection performance. The standard states that sealing defects are often a significant indicator of problems with the heat sealing process, and may also further expose Encasement defects after physical performance testing. The test is applied to at least one transparent surface of the Encasement so that the inspector can clearly observe the sealing area. When used, it should be noted that the test results in the standard are expressed in SI units or inch-pound units, depending on the system configuration. Users should ensure appropriate safety measures and confirm applicable regulatory restrictions before use.
