Full title and description

Small-bore connectors for liquids and gases in healthcare applications — Part 7: Connectors for intravascular or hypodermic applications. This edition specifies dimensional and performance requirements for Luer-type small-bore connectors used with intravascular and hypodermic medical devices and accessories.

Abstract

This standard sets out dimensions, general requirements and functional performance tests for small-bore (Luer) connectors intended for intravascular or hypodermic applications (examples: hypodermic syringes, needles, IV cannulae with Luer slip or Luer lock interfaces). It clarifies that device-specific requirements remain in the particular medical device standards and includes informative and normative annexes supporting design, reference connectors and rationale.

Scope

ISO 80369-7:2021 specifies dimensions and performance requirements for small-bore connectors with a 6% (Luer) taper intended for intravascular or hypodermic applications. The document does not set requirements for whole medical devices that incorporate these connectors; those requirements are given in the relevant particular-device standards. The standard excludes certain connector types addressed by other standards (for example specific blood‑compartment ports and infusion closure piercing connectors).

Key topics and requirements

• Dimensional requirements and tolerances for male and female Luer slip and Luer lock connectors.
• Performance testing requirements including fluid leakage (positive pressure and subatmospheric), resistance to separation (axial load and unscrewing), resistance to overriding, and stress‑cracking assessments.
• Reference connectors and normative annexes that define test fixtures and reference geometries used for conformity assessment.
• Guidance and rationale (informative annexes) on safe design and usability considerations for intravascular/hypodermic connections.
• Clarification that the Luer connector design was originally intended for certain pressures (historical note) and that device designers should verify suitability for intended use.

Typical use and users

Primary users include medical device designers and manufacturers of syringes, needles, IV cannulae, infusion sets and related accessories; testing and quality laboratories conducting connector conformity tests; regulatory and procurement professionals evaluating connector safety; and standards committees and usability engineers working to reduce misconnections. Regulatory bodies and healthcare organizations reference the standard when assessing connector safety and compatibility.

Related standards

ISO 80369-7 is part of the ISO 80369 series (general requirements and application‑specific parts such as breathing systems, enteral, urethral/urinary, limb cuff inflation, neuraxial and common test methods in Part 20). It replaces the earlier ISO 80369-7:2016 edition and cross-references other device‑specific standards (for example ISO 8637 and ISO 8536‑4 for some connector types). National and regional adoptions (EN/ISO editions) and test method documents (ISO 80369-20) are often used alongside this part.

FAQ

Q: What is this standard?

A: ISO 80369-7:2021 is an international standard that defines dimensional and performance requirements for small-bore (Luer) connectors intended for intravascular and hypodermic medical applications.

Q: What does it cover?

A: It covers geometry, tolerances and a suite of functional tests (leakage, separation forces, resistance to unscrewing/overriding, stress cracking and related assessments), plus annexes with reference connectors and guidance; it does not replace device‑specific requirements found in particular medical device standards.

Q: Who typically uses it?

A: Manufacturers and designers of syringes, needles, IV and infusion components; testing laboratories; regulatory reviewers; procurement and clinical engineering teams; and standards developers working to reduce misconnections. Regulatory agencies reference the ISO 80369 series when assessing connector safety.

Q: Is it current or superseded?

A: The 2021 edition (Edition 2) is the current published edition, replacing ISO 80369-7:2016. Users should verify they are using the 2021 text for compliance and testing.

Q: Is it part of a series?

A: Yes — ISO 80369 is a multipart series addressing small-bore connectors for different clinical applications (Parts 1, 2, 3, 4, 5, 6, 7 and 20 for common test methods). Part 7 specifically addresses intravascular and hypodermic Luer connectors.

Q: What are the key keywords?

A: Luer, small-bore connector, intravascular, hypodermic, connector dimensions, leakage, separation force, ISO 80369-7, connector testing.
