ISO 80369-7 specifies key dimensions and functional performance requirements for small-bore connectors used in intravascular and hypodermic medical device connections, including common Luer slip and Luer lock styles.
Because connector compliance often drives inspection, leak testing, and mechanical verification plans, it helps to align your lab setup to the exact edition and the acceptance criteria used in your design history file.

ISO 80369-7: Small-bore connectors for liquids and gases in healthcare applications — Part 7: Connectors for intravascular or hypodermic applications
ISO 80369-7 is an International Standard focused on the connector interface itself. It defines dimensional requirements and functional performance expectations for small-bore connectors intended for intravascular and hypodermic applications.
This document is typically applied during connector design control, incoming inspection of molded or machined connector components, and verification/validation testing for devices and accessories that use Luer-type connections.
Quick Definition
What it is: A connector-interface standard for intravascular and hypodermic small-bore connections (commonly Luer slip and Luer lock).
What it does: Defines dimensional requirements and functional performance requirements for the connector design.
What it is not: A complete device performance standard for the full medical device or accessory that uses the connector.
What This Standard Covers
ISO 80369-7 addresses connector design and performance at the mating interface used for intravascular or hypodermic connections. In practice, it is used to control fit, compatibility, and functional performance of the connector pair (male/female), including common slip and locking configurations.
The standard is commonly applied to connector components and connector assemblies on medical devices and accessories rather than to the clinical function of the device.
Why This Standard Matters in Testing
For intravascular and hypodermic applications, connector performance directly affects leakage risk, robustness of the connection, and usability during assembly and clinical handling. ISO 80369-7 is often treated as a core requirement when demonstrating that a Luer-type interface meets dimensional and functional expectations.
It can also influence supplier quality controls, because minor dimensional variation at the taper, threads, or sealing surfaces can change leak performance and connection/disconnection behavior.
Common Materials, Product Types, or Applications Covered
ISO 80369-7 is commonly used when designing or qualifying connectors used with intravascular lines and hypodermic connections.
Common examples: Hypodermic syringes and needles; IV cannulae and accessories using Luer slip or Luer lock connectors.
Common connector manufacturing materials: Medical-grade polymers and metals used for connector components (material selection and conditioning are typically controlled by the device-specific standards and the manufacturer’s design requirements).
Common Test or Verification Workflow
ISO 80369-7 is usually supported by a combination of dimensional inspection and performance verification testing using defined connector samples and reference connectors (as applicable).
Common verification activities: Dimensional measurements of critical connector features; functional fit checks with mating connectors; leakage performance testing under relevant pressure conditions; mechanical checks related to separation and disconnection behavior for locking connectors.
Many organizations pair ISO 80369-7 requirements with ISO 80369-series general requirements and common test-method references when building a repeatable verification plan.
Equipment Commonly Used for This Standard
Equipment selection typically depends on whether you are doing dimensional release inspection, design verification, or production lot conformance testing. The standard’s requirements most often drive metrology, leak testing, and basic mechanical testing capabilities.
Common equipment families: Optical measurement systems or CMMs for connector geometry; gauges and fixtures appropriate to Luer-style features; leak test instruments (e.g., pressure/vacuum-based methods, depending on your test plan); universal test machines for axial load/separation-type checks; torque measurement for lock/unlock characterization where applicable.
If you are comparing fixtures, load cells, or leak-test configurations for a connector verification plan, you can request a detailed quote for a setup matched to your throughput and reporting needs.
How to Read This Designation or Revision
ISO 80369-7 identifies Part 7 within the ISO 80369 small-bore connector series (healthcare liquids and gases). The part number indicates the application category covered by the connector interface requirements.
Revision sensitivity: Test expectations and acceptance criteria can change between editions. Many quality systems and regulatory submissions require you to use (and report) the exact cited edition (for example, “ISO 80369-7:2021”).
Related Standards, Methods, or Frameworks
Depending on how your verification plan is structured, ISO 80369-7 is commonly used alongside other ISO 80369-series documents that address general requirements and common test methods for small-bore connectors.
Commonly paired references: ISO 80369-1 (general requirements across the series) and ISO 80369-20 (common test methods used to evaluate performance requirements across connector parts).
