ASTM F2338 is a widely recognized standard for container closure integrity testing (CCIT) using the vacuum decay method. It detects leaks by monitoring pressure loss inside a sealed chamber, indicating gas escape from defective packaging. This non-destructive and deterministic approach eliminates subjectivity associated with traditional methods like dye ingress. The method is highly suitable for pharmaceutical and medical device packaging, offering repeatable and quantitative data for quality control and validation. ASTM F2338 supports testing of various package formats, including rigid containers, pouches, and trays, helping manufacturers ensure sterility, prevent contamination, and meet regulatory expectations for packaging integrity.
