Overview
SIST EN IEC 63522-14:2025 specifies the standardized test methods and measurement requirements for evaluating mould growth on electrical relays. This European and international standard, developed by the Slovenian Institute for Standardization (SIST) and aligning with IEC guidelines, defines procedures to assess how susceptible relays are to mould growth during transportation, storage, and operational use. The scope covers detailed testing intended to determine the potential impact of mould growth on relay performance and other key functions.
Electrical relays exposed to humid, warm, or contaminated environments can support or be affected by mould growth. This standard ensures manufacturers and users can evaluate the durability and functional reliability of relays under such conditions, enhancing the design and selection process for critical electrical components.
Key Topics
- Mould Resistance in Relays: The standard outlines test procedures for evaluating relays' resistance to mould under controlled conditions, based on IEC 60068-2-10 (Test J).
- Test Methods: Includes guidance for preparing the device under test (DUT), incubation methods, severity levels, and functional verification after exposure.
- Performance Impact Assessment: Specifies evaluation criteria to determine if mould presence affects relay electrical or mechanical performance.
- Reporting Requirements: Details the structure of test reports, including initial conditions, methods, results, and any performance changes observed.
- Harmonization: Harmonized with European and international standards, ensuring broad applicability across markets and regulatory environments.
Applications
Implementing SIST EN IEC 63522-14:2025 is essential for:
- Relay Manufacturers: Integrating mould growth testing into product qualification and quality assurance processes to verify environmental robustness.
- Product Designers: Selecting materials and relay types less susceptible to mould, thereby improving reliability for applications in harsh or humid environments.
- Industrial and Commercial End Users: Assessing relay compatibility for use in sectors such as transportation, energy, automation, or infrastructure, where exposure to mould-promoting environments is likely.
- Certification and Compliance: Demonstrating conformity to international standards in procurement, tendering, and certification, particularly for export or regulated projects.
By following this standard, stakeholders can enhance relay reliability, avoid premature failures, and ensure product longevity even under challenging conditions where mould growth is a concern.

Practical Value
Adopting SIST EN IEC 63522-14:2025 helps stakeholders:
- Mitigate Risk: Identify and resolve vulnerabilities in relay design regarding mould exposure.
- Enhance Quality: Meet customer and regulatory expectations by providing documented evidence of product resilience.
- Streamline Certification: Leverage clear and harmonized testing protocols for international acceptance.
- Optimize Applications: Ensure long-term reliability for installations in climates or environments where mould growth is prevalent.
By embedding the principles and procedures of this standard, organizations can significantly improve the lifecycle performance and customer trust in electrical relay products.
