Full title and description

ISO 80369-20:2024 — Small-bore connectors for liquids and gases in healthcare applications — Part 20: Common test methods. This document specifies the common test methods used to evaluate the performance requirements applicable to small-bore connectors in the ISO/IEC 80369 series and related ISO 18250 series, providing standardized mechanical, dimensional and leakage test procedures for connector safety and compatibility in medical applications.

Abstract

This part of ISO 80369 defines the common test methods for assessing connector performance (for example tensile, torque, leakage, pressure/burst, dimensional verification and durability). It includes guidance notes and rationale for some clauses (see Clause A.2). The 2024 edition updates and replaces the 2015 edition to reflect consolidated test practices across the 80369 family.

Scope

ISO 80369-20:2024 specifies the common test methods to evaluate the performance requirements for small-bore connectors intended for use in healthcare applications. The tests apply to connector designs within the ISO and IEC 80369 series and to related connector families described in the ISO 18250 series; they are intended to provide repeatable, comparable procedures for mechanical, dimensional and leakage testing used during design verification, production control and conformity assessment. The 2024 edition supersedes the 2015 edition and harmonizes test approaches across the 80369 family.

Key topics and requirements

• Dimensional verification and go/no‑go tests to confirm connector geometry and tolerances.
• Tensile and axial strength tests for connector mating and retention forces.
• Torque and rotational force tests for locking or rotating‑collar connectors.
• Leakage and pressure tests (including burst and sustained pressure) to verify fluid/gas containment.
• Connection/disconnection force measurement and cycle‑life (durability) testing.
• Flow restriction and backflow assessment where applicable to intended use.
• Material and biocompatibility considerations insofar as they affect test outcomes and performance.
• Test specimen conditioning, environmental and ageing preparations to reproduce clinical/field conditions.

Typical use and users

This standard is used by medical device manufacturers, connector designers, independent test laboratories, notified bodies and regulatory assessors for design verification, product development, supplier qualification and conformity assessment. It is referenced by product development teams (mechanical and clinical engineers), quality systems and regulatory submissions (for example conformity documentation and premarket dossiers). Regulators and guidance documents (such as those from the FDA) reference the 80369 family and related test expectations when assessing misconnection risk mitigation.

Related standards

ISO 80369-20 is part of the broader ISO 80369 family (including Part 1 — general requirements, and application‑specific parts such as Part 2 respiratory, Part 3 enteral, Part 5 limb cuff inflation, Part 6 neuraxial, Part 7 intravascular/hypodermic, etc.). It also complements the ISO 18250 connector series and is often used in conjunction with national/adopted documents and industry guides (AAMI/ANSI adoptions and regulatory guidance). The 2024 edition replaces ISO 80369-20:2015 and aligns common test methods across these related parts.

Q: What does it cover?

A: It covers standardized procedures for dimensional checks, tensile and torque testing, leakage and pressure testing, connection/disconnection force measurement, cycle‑life/durability tests and specimen conditioning — all intended to produce repeatable results for connector performance across the 80369 family.

Q: Who typically uses it?

A: Medical device manufacturers, connector designers, independent test laboratories, regulatory reviewers, notified bodies and quality teams use the standard for design verification, supplier qualification, production testing and regulatory submissions.

Q: Is it current or superseded?

A: It is current: the second edition was published in November 2024 and supersedes ISO 80369-20:2015.

Q: Is it part of a series?

A: Yes — ISO 80369-20 is part of the ISO 80369 series of standards (Part 1 general requirements and multiple application‑specific parts). It is intended to be used alongside those parts and related series such as ISO 18250; many national and industry bodies reference the 80369 series.
