Overview
IEC 60512-23-3:2000 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies basic testing procedures and measuring methods for assessing the shielding effectiveness of electromechanical connectors and accessories used in electronic equipment. This standard defines a test method called Test 23c, which measures the ability of a connector or a connector assembly (including accessories and terminated cables) to provide a continuous 360° electromagnetic shield. The goal is to ensure reliable protection against electromagnetic interference (EMI) throughout the entire length of the connector assembly.
This standard, part of the IEC 60512 series on electromechanical components, supports manufacturers, engineers, and quality assurance professionals by providing a uniform procedure to evaluate connector shielding performance, fostering product reliability and ensuring compliance with electromagnetic compatibility (EMC) requirements. The current edition includes updates from the April 2003 corrigendum.
Key Topics
- Scope and Object: Defines the test method to measure shielding effectiveness of connectors, accessories, and cable assemblies, ensuring continuous 360° shielding.
- Test Methodology: Uses a line injection principle with detailed preparation steps for different connector types, such as cylindrical, rectangular, and printed board connectors.
- Frequency Range: The standard specifies the applicable frequency range for testing, which is critical in evaluating shielding performance against EMI across relevant operational bands.
