Overview
ISO 21882:2019 - "Sterile packaged ready for filling glass vials" defines the characteristics and minimum requirements for sterile, ready‑for‑filling glass vials intended for injectable preparations. The standard addresses materials, packaging systems (sterile barrier systems and protective packaging), process controls and analytical test methods required to deliver washed, sterilized empty vials suitable for aseptic filling.
Key topics and technical requirements
- Scope and intent: Specifies attributes of sterile packaged vials, packaging configurations and analytical testing to support aseptic presentation at point of use.
- Quality system and testing: Requires a formal quality system, statistically valid sampling plans (examples: ISO 2859‑1, ISO 3951), calibrated test equipment and ambient laboratory conditions for testing.
- Process steps: Defines processes for washing (final rinse with Water for Injection), optional drying (air filtered to ≤ 0.22 µm), packaging and validated sterilization to a sterility assurance level (SAL) of 10‑6 using appropriate methods.
- Sterilization: Sterilization methods must be validated (examples referenced: ISO 11135, ISO 17665‑1, ISO 11137, ISO 14937) and compatible with sterile barrier systems per ISO 11607‑1; ethylene oxide residuals per ISO 10993‑7.
- Glassware requirements: Covers material, dimensions (aligned with ISO 8362 series), particle containment (visible and sub‑visible), and bacterial endotoxin testing. (See Annexes for sample preparation and test methods.)
- Packaging system design: Details configurable sterile barrier systems including nest and tub (for automated filling) and tray configurations (for manual/semi‑automated filling), plus components such as insert liners, sealing lids and protective bags. Informative annexes provide design examples and packaging configurations.
- Marking and labelling: Requirements for traceability, batch information and manufacturer/customer information on tubs/trays and protective packaging.
Practical applications - who uses ISO 21882:2019
- Pharmaceutical manufacturers procuring sterile ready‑for‑filling vials for aseptic production or clinical trial fills.
- Primary packaging suppliers designing and validating nest/tub and tray systems for sterile delivery.
- Contract packers and sterile service providers implementing validated sterilization cycles and packaging integrity programs.
- Quality control and analytical labs performing particulate, endotoxin and sterility assurance testing.
- Regulatory and compliance teams ensuring packaging and primary container systems meet pharmacopoeial and ISO expectations.
