Overview
ISO 5356-2:2012/Amd 1:2019 is an important amendment to the international standard focused on anaesthetic and respiratory equipment. Specifically, it addresses conical screw-threaded weight-bearing connectors, which play a crucial role in ensuring safe and reliable connections between heavier or fragile breathing components. The amendment updates the original Part 2 of ISO 5356 to enhance compatibility, safety, and performance of these connectors in medical environments.
This standard is maintained by ISO Technical Committee ISO/TC 121, Subcommittee SC 1, specializing in breathing attachments and anaesthetic machines. The document builds upon the foundations laid out in ISO 5356-1:2015, which specifies requirements for lighter weight cones and sockets.
Key Topics
- Screw-threaded weight-bearing connectors: Designed to support substantial equipment loads during anaesthesia and respiratory procedures.
- Compatibility: Connectors conforming to this standard must remain compatible with cones and sockets defined in ISO 5356-1:2015, enabling flexible and safe component interchange.
- Misconnection prevention: Although the connectors aim to reduce inadvertent misconnection risks, ultimate responsibility for correct assembly lies with the user.
- Measurement and functional testing: Compliance verification requires precise measurement and functional testing to ensure connector performance and safety.
- Standardized dimensions: Key dimensional specifications such as the 22 mm cone and socket sizes are referenced, supporting uniformity and interoperability.
Applications
ISO 5356-2:2012/Amd 1:2019 is primarily used within the healthcare sector, particularly in the design and manufacture of:
- Anaesthetic machines and breathing systems requiring robust, weight-bearing connectors.
- Respiratory equipment where heavier or fragile components demand secure and reliable connections.
- Medical device manufacturing focused on patient safety through standardized connector designs.
- Hospital and clinical settings where compatibility between various breathing apparatus parts is essential.
By adhering to this standard, manufacturers and healthcare providers ensure enhanced safety, reliability, and consistent performance in critical medical equipment interfaces.
Related Standards
- ISO 5356-1:2015 – Anaesthetic and respiratory equipment - Conical connectors - Part 1: Cones and sockets. This is the foundational standard for lightweight connectors compatible with ISO 5356-2 designs.
- ISO 121 (Anaesthetic and respiratory equipment series) – covers broader aspects of anaesthetic and respiratory safety and device interoperability.
- ISO/IEC Directives, Part 1 and 2 – outline procedural and editorial rules governing the drafting and maintenance of ISO international standards.
Conclusion
ISO 5356-2:2012/Amd 1:2019 is a critical amendment enhancing the design and safety requirements for weight-bearing, screw-threaded conical connectors in anaesthetic and respiratory equipment. It ensures interoperability with lighter connectors, promotes resistance to misconnection, and requires thorough testing for compliance. This standard supports manufacturers and healthcare professionals in delivering reliable, high-quality respiratory systems critical to patient care.
