General Information
Overview
EN IEC 63522-29:2025 is an international standard published by CLC that defines the testing and measurement methods for capacitance in electrical relays. This part 29 of the IEC 63522 series specifically addresses the evaluation of capacitances formed by components within electrical relays to ensure they do not exceed specified limits. The standard applies to various types of relays, including electromechanical, reed, solid state, time relays, and hybrid technologies. It aims to verify relay performance under conditions expected during transportation, storage, and operational use.
By establishing consistent testing procedures and limits for capacitance, EN IEC 63522-29:2025 helps manufacturers, testing labs, and quality assurance professionals confirm the electrical reliability and safety of relays in practical applications.
Key Topics
- Scope and Application: Testing capacitance in all kinds of electrical relays to assess performance during transportation, storage, and use.
- Measurement Procedure: Specifies use of a measuring bridge at 1 kHz frequency and voltage not exceeding 10 V (unless otherwise instructed by the manufacturer).
- Parameters to Specify:
- Measuring frequency and voltage, if different from the standard.
- Measurement points and grounding scheme.
- Limiting capacitance values based on manufacturer or application standards.
- Any test conditions deviating from related general standards.
- Evaluation Criteria:
- Pass criteria when measured capacitances are within limits.
- Fail criteria when capacitances exceed limits.
- Test Reporting:
- Detailed descriptions including device under test, measured capacitances, measurement setup, limits, results, and test conditions must be documented.
- Terminology: Complies with IEC 63522-0 definitions and terms, ensuring coherence across the relay testing standards suite.
Applications
EN IEC 63522-29:2025 is essential in industries where reliable and safe operation of electrical relays is critical, including:
- Industrial Automation: Ensures control relays meet capacitance criteria for stable switching and signal integrity.
- Railway and Transportation Systems: Validates relays withstand vibration and environmental stresses without capacitance-related failures.
- Energy and Power Generation: Assesses relay components critical for protective functions and operational robustness.
- Consumer Electronics and Appliances: Confirms solid state and time relays operate within safe capacitance ranges to maintain product safety.
- Quality Control and Certification Labs: Provides standardized procedures and documentation templates for testing capacitance in relay devices.
By applying this standard, manufacturers and testing bodies can better predict relay behavior and compliance during real-world usage, reducing failure risks associated with unintended capacitance effects.
Related Standards
- EN IEC 63522-0 (General and Guidance): Provides overarching principles and general testing methods applied in conjunction with Part 29 for capacitance.
- IEC 61810-1 (Electromechanical Elementary Relays - General and Safety Requirements): Complements capacitance testing by defining fundamental safety and performance criteria.
- IEC 63522 Series - Electrical Relays Tests and Measurements: The broader series covering various test methods applicable to different relay parameters beyond capacitance.
