ISO 23416:2023

Overview

ISO 23416:2023 - General specifications and testing methods for temperature-sensitive medicinal packages in good distribution practice principles - defines general specifications and validation test methods for temperature-sensitive medicinal packaging used in Good Distribution Practice (GDP). The standard focuses on passive insulated containers (no power source) and covers procedures for temperature-recording, thermal performance testing, dimensional and weight capacity verification, and robustness assessment. It does not cover active (powered) packaging systems or guarantee product quality under all special conditions.

Key topics and technical requirements

• Scope & definitions: Clarifies terms such as temperature-sensitive medicinal product, data logger, phase changing material (PCM), insulated container, and validation consistent with ISO vocabulary references.
• Thermal performance: Requires validation of passive packaging to maintain target temperature ranges. Test methods include temperature profiling, sensor placement, and continuous temperature-recording.
• Temperature-recording equipment: Recommends battery-operated thermistor or thermocouple multi-channel data loggers with resolution of 0.1 °C and accuracy of ±1.0 °C, and capability to store digital readings at set intervals.
• Physical performance & robustness: Specifies tests for container durability and resistance to handling stresses throughout the supply chain (robustness testing as specified in clause 6.3).
• Dimensional stability & capacity: Containers should maintain dimensional stability (ISO 3394 module dimensions recommended) and meet documented storage and weight capacity tests.
• Safety & materials: Coolants and PCMs must meet safety requirements consistent with ISO 22982-1; packaging must not adversely affect medicinal product quality.
• Preparation & packing practices: Guidance on pre-cooling containers, locating sensors, avoiding direct sunlight, and calculating coolant/PCM mass based on experimental data or agreements.

Practical applications and who uses it

ISO 23416:2023 is intended for stakeholders responsible for the transport, storage and handling of temperature-sensitive medicines:

• Pharmaceutical manufacturers and packagers validating shipping systems
• Distributors, wholesalers and logistics providers implementing GDP-compliant cold chain
• Quality assurance, regulatory and compliance teams defining acceptance criteria and test reports
• Cold-chain equipment suppliers (passive thermal containers, PCM/coolants, data loggers)
• Clinical trial sponsors and immunization programs requiring validated transport packaging

Practical uses include qualifying insulated containers for vaccine or biologic shipments, designing packing protocols (pre-cooling, PCM selection), and documenting validation results for audits.
