  • Container Closure Integrity Testing is a non-destructive measurement technology based on the following testing methods:
  • Vacuum Decay Test Method
  • Pressure Decay Test Method
  • Measurement is achieved by applying a pressure differential into an airtight testing chamber enclosing the container.
  • The test objective is to detect container leakages by measuring the reached pressure level as well as the pressure change over test time.

Quality Assurance

  • Equipment test method refers to:
    • Approved industry standard "ASTM F2338-09": "Standard Test Method for Non-Destructive Detection of Leafs in Packages"
    • United States Pharmacopoeia – USP General Chapter «1207» “Packaging Integrity Evaluation”
    • EU Guidelines to GMP Medicinal Products for Human and Veterinary Use – Annex 1 “Manufacture of Sterile Medicinal Products”
    • PDA Technical Report No. 27 “Pharmaceutical Package Integrity”
    • FDA 21 CFR part 11 as well as EMA Annex 11
