Overview
IEC 61347-2-8:2024 is an international standard developed by the International Electrotechnical Commission (IEC) that sets forth safety requirements for ballasts used with fluorescent lamps. This standard applies to ballasts - excluding resistance types - designed for use on alternating current (AC) supplies up to 1,000 V at either 50 Hz or 60 Hz, and is relevant for fluorescent lamps with or without pre-heated cathodes, operated with or without a starter or starting device. The standard covers ballasts associated with lamps that conform to the rated powers, dimensions, and characteristics specified in IEC 60081 and IEC 60901.
This second edition of IEC 61347-2-8 revises and replaces the first edition (2000) and Amendment 1 (2006). Key updates include the introduction of dated references and the alignment of clause numbering with those in IEC 61347-1, ensuring better consistency and easier cross-referencing.
Key Topics
- Scope of Coverage: Safety requirements for non-resistance ballasts used in fluorescent lamp circuits, including components such as reactors, transformers, and capacitors.
- Test Methods: Detailed guidelines for endurance, insulation, and high-voltage impulse testing specific to ballasts.
- Marking and Information: Requirements for mandatory markings and information disclosure to ensure correct ballast identification and safe usage.
- Thermal and Electrical Safety: Procedures for testing thermal endurance and limiting temperatures to avoid electrical hazards.
- Construction and Materials: Requirements for the use of materials-such as types of mouldings and insulating components-to ensure resistance to heat, fire, tracking, and corrosion.
- Compliance with Related IEC Standards: References to companion standards (including IEC 61347-1, IEC 60081, and IEC 60901) for a cohesive and harmonized safety framework.
- Updated Terminology and Definitions: Use and reference of internationally standardized terminology via IEC Electropedia.
Applications
IEC 61347-2-8:2024 is essential for manufacturers, testing laboratories, and certifying organizations involved in producing or assessing ballasts for fluorescent lighting systems. Practical applications include:
- Product Design and Compliance: Ensuring that new and existing ballasts meet international safety requirements, reducing liability and risk.
- Certification and Approval: Providing a verified basis for product certification and market acceptance in regions adhering to IEC standards.
- Quality Assurance: Supporting in-house and third-party product safety verification, including performance against abnormal conditions and durability over time.
- Installation and Maintenance: Informing installers and maintenance personnel about proper use, maximum allowed temperatures, and safety markings for ballasts.
By following IEC 61347-2-8:2024, stakeholders can ensure reliable and safe operation of fluorescent lamp systems, minimize the risk of electrical hazards, support global market access, and achieve sustainability and longevity in lighting applications.
