Overview
ISO 13408-6:2021 - Aseptic processing of health care products - Part 6: Isolator systems specifies requirements and guidance for the specification, selection, qualification, bio‑decontamination, validation, operation and control of isolator systems used in aseptic processing. The standard covers isolators for conventional pharmaceutical and cell‑based health care products, clarifies design and validation expectations, and supports contamination control strategies. It does not cover Restricted Access Barrier Systems (RABS), sterility‑testing isolators, nor does it replace national Good Manufacturing Practices (GMPs) or other regulatory requirements.
Key topics and technical requirements
ISO 13408-6:2021 addresses the full lifecycle of isolator systems, including:
- Quality system elements and a risk‑based approach to system specification.
- Basic principles of isolator systems, including negative‑pressure designs.
- Design requirements: materials of construction, air‑handling (airflow patterns, particulate specifications, recirculation, pressure differentials), ergonomics and operator interfaces (gloves, sleeves, suits).
- Transfer and access: design and use of transfer ports and devices for portable/mobile equipment.
- Bio‑decontamination: agent selection, generation, process development, parameters, aeration, residue limits and log‑reduction expectations for validated processes.
- Validation and qualification: design qualification (DQ), installation qualification (IQ), operational qualification (OQ) and performance qualification (PQ), plus cleaning and sterilization validation.
- Routine control and monitoring: system integrity, environmental monitoring, bio‑decontamination process monitoring, change control, maintenance and calibration.
- Personnel training and requalification requirements.
These topics align with industry expectations for validated aseptic manufacturing and contamination control.
Practical applications and who uses it
ISO 13408-6 is intended for organizations and professionals involved in aseptic manufacturing and containment, including:
- Pharmaceutical and biologics manufacturers (sterile drug products, cell and gene therapy)
- Medical device manufacturers producing sterile devices
- Quality assurance, validation and regulatory affairs teams
- Contamination control and facilities engineering teams
- Contract manufacturing organizations (CMOs) and equipment suppliers designing or qualifying isolator systems
Applying this standard helps organizations design isolator systems that support sterility assurance, meet validation expectations, and integrate with existing GMP frameworks.
