EN 60512-23-4:2001

Overview

EN 60512-23-4:2001 (CLC) specifies test methods for evaluating connector behaviour as a discontinuity in a controlled-impedance transmission line by measuring transmission line reflections in the time domain. The standard defines two test methods to quantify how a connector produces reflections when inserted into a transmission path. It is part of the broader EN/IEC 60512 series covering tests and measurements for connectors, with a focus on screening and filtering performance in time-domain reflection measurements.

Key Topics

• Time-domain reflection measurement: Procedures to capture reflections caused by the connector when used in a transmission line; the connector is treated as an impedance discontinuity.
• Two test methods: The standard defines two distinct approaches to measure reflections (method details are contained in the normative text).
• Controlled characteristic impedance: Tests require a transmission line environment with specified characteristic impedance to ensure repeatable, comparable results.
• Screening and filtering context: Results inform how connectors affect signal integrity, screening (shielding) and filtering performance in real installations.
• Interpretation of reflections: Guidance for assessing reflection signatures to identify impedance mismatches or discontinuities introduced by connector interfaces.

Applications

EN 60512-23-4 is practical for professionals who need to evaluate connector performance where signal fidelity and electromagnetic compatibility matter:

• Connector manufacturers - to verify design performance, production control and compliance with time-domain reflection requirements.
• Test laboratories - to provide standardized test reports for customers and compliance certification.
• Product designers and systems engineers - to select and qualify connectors for high-speed data, RF, or mixed-signal assemblies where impedance continuity is critical.
• EMC and signal-integrity engineers - to assess how connector-induced reflections affect shielding, filtering and overall system performance.
• Quality and compliance teams - to incorporate time-domain reflection testing into acceptance and incoming-inspection procedures.
