ISO 5360:2016

Overview

ISO 5360:2016 - "Anaesthetic vaporizers - Agent‑specific filling systems" defines functional and dimensional requirements for agent‑specific filling systems used with liquid volatile anaesthetic agents. The standard specifies the geometry and interaction of components such as bottles, bottle collars, bottle adaptors (male adaptors / connectors), and filler receptacles, and addresses performance aspects including filling rate, leakage, overfilling protection, colour coding, usability and clinical evaluation.
Note: dimensions for desflurane are not specified because of its unique properties, and the standard does not prescribe construction materials (Annex A provides material recommendations).

Key topics and technical requirements

• Dimensional specifications for bottle necks, bottle collars, bottle connectors and male adaptors - agent‑specific coding prevents cross‑connection of different anaesthetic agents.
• Bottle collar design and position: collar must be attached to the bottle, rotatable by hand, and located relative to the screw thread per the standard’s figures and tables.
• Adaptor engagement: threads must ensure at least 0.75 turns engagement on a threaded neck and resist a tightening torque of (3 ± 0.3) N·m without visible damage.
• Sealing and protection: requirements for sealing ports when adaptors are not inserted and for overfilling protection to reduce spills and atmospheric release.
• Mechanical robustness: e.g., bottle adaptors shall not break when dropped from 1 m onto a hard surface.
• Leakage and emission testing: methods to determine total leakage to atmosphere during filling (normative Annex C).
• Colour coding and labelling: specified colours and marking conventions to support correct agent identification and safe clinical use.
• Usability and clinical evaluation: human factors considerations and manufacturer information (marking, labelling, instructions for use).

Practical applications

ISO 5360:2016 is used to:

• Guide design and manufacture of agent‑specific filling components for anaesthetic vaporizers and bottles.
• Define acceptance criteria for supplier and incoming inspection of bottle collars, adaptors and filler receptacles.
• Support test labs and QA teams performing leakage, durability and usability tests.
• Inform regulators, procurement and clinical engineers evaluating compatibility and safety of vaporizer filling systems.
• Reduce risk of cross‑contamination and accidental misfilling through standardized mechanical coding and colour identification.

Who should use this standard

• Medical device manufacturers (vaporizers, bottle adaptors, anaesthetic bottles)
• Design and mechanical engineers working on anaesthetic equipment
• Regulatory and compliance teams, test laboratories and clinical engineering departments
• Hospital procurement and safety officers responsible for equipment compatibility

Related standards

• Normative reference: ISO 1101 (geometrical tolerancing).
• Developed under ISO/TC 121 (Anaesthetic and respiratory equipment, SC 1).
