Përmbledhje standarde

Maintaining the sterility of parenteral drugs is a critical concern in the pharmaceutical and medical device industries. ISO 8871-5 provides a structured testing approach for assessing the functional integrity of elastomeric closures used with injection vials. Specifically, it outlines procedures to determine vial rubber closure self-sealing performance and closure-vial interface tightness under simulated stress conditions.

ISO 8871-5

Përshkrimi standard

ISO 8871-5, titled “Elastomeric parts for parenterals and for devices for pharmaceutical use – Part 5: Functional requirements and testing”, defines the performance requirements and testing methods for rubber stoppers used in sterile medical containers. These closures often undergo repeated piercing by hypodermic needles and must preserve container integrity by resealing effectively.

Failure in vial leak test results can compromise sterility, risking contamination, incorrect dosing, or degraded efficacy. That’s why manufacturers and quality control professionals follow this standard closely for regulatory compliance and patient safety assurance.

Vial Rubber Closure Self-Sealing and Dye Ingress Testing

Self-sealing ability is one of the most critical properties assessed under ISO 8871-5. The vial rubber closure self-sealing test simulates repeated needle punctures and evaluates if the closure reseals effectively under vacuum pressure.

In Annex C and D of ISO 8871-5, two primary vial leak test procedures are specified:

  1. Fill each clean vial with particle-free water.

  2. Seal the vial using closures and crimp caps per ISO 8362.

  3. Using fresh hypodermic needles, pierce each rubber stopper 10 times, varying positions each time.

  4. Immerse the vials in 1 g/L methylene blue solution.

  5. Place the immersed vials in a vacuum chamber and reduce pressure by 27 kPa for 10 minutes.

  6. Restore atmospheric pressure, keep immersed for another 30 minutes.

  7. Rinse and visually inspect for blue dye inside the vial.

This test determines if the closure maintains its self-sealing capability after repeated use.

This evaluates the integrity of the vial-closure system without prior puncture. Vials are prepared, sealed, submerged in dye, and vacuum-pressurized similarly, then inspected for dye ingress.

FAQ about ISO 8871-5

1. What does ISO 8871-5 test for?

ISO 8871-5 evaluates the self-sealing and seal integrity of elastomeric closures used in pharmaceutical vials.

It involves repeated needle punctures of closures, immersion in dye, and vacuum exposure to detect leaks through visual inspection.

It ensures that the vial maintains sterility after multiple punctures, especially in multi-dose containers.

You need ISO 8362-compliant vials and closures, methylene blue dye, hypodermic needles, and a vacuum chamber. A vial leak testing machine like the LSSD-01 simplifies the process.

Yes. Cell Instruments offers customizable systems, automation upgrades, and expert training to help clients meet ISO testing requirements.
