A Study for the Development of A Movable Leakage Tester By Creating Vaccum Through Reliability Analysis

Abstract

Chemical and biological materials are a means of defense that can protect life from enemy chemical attacks and terrorist warfare and are a weapon system essential for the survival and maintenance of the combat power of the military. According to a recent study, the CSRP test results from 2007 to 2023 showed that leakage testing has the greatest influence among several factors on whether or not the shelf life of permeability protection is extended. The rate of packaging leakage from the product increased as the storage period elapsed. If a leak occurs in a chemical protective suit, the product can no longer be used for combat purposes and is converted to use for educational purposes, which is a factor in increasing the operating costs due to the replacement of new products. Accordingly, this study developed a leak tester capable of field measurements using a vacuum to overcome the limitations of current leak tests. This paper presents a method for calculating the appropriate interval using a confidence level.
