IEC 60695 Fire Hazard Testing of Electrical Equipment
The IEC 60695 series is a comprehensive set of international standards that cover the electrical and thermal testing methods for materials used in the manufacture of electrical equipment. Within this context, one critical standard is IEC 60695-11: “Fire hazard and electrical safety—Part 11: Glow-wire flame test.” This glow-wire flame test evaluates the flammability of materials under controlled conditions to ensure they meet specified fire resistance requirements.
The test involves heating a small wire (typically made of tungsten) to a specific temperature, usually around 750°C, and then bringing it into contact with the specimen material. The time taken for the material to ignite is measured, as well as the duration during which it continues to burn after removal from the glowing wire. These parameters are crucial in assessing how materials will behave in real-world scenarios where fire hazards may arise.
The glow-wire flame test plays a pivotal role in ensuring that electrical equipment does not pose a significant fire risk, especially for components like terminals, connectors, and other parts exposed to heat or friction. This testing method is widely used across various industries, including marine and ship equipment manufacturing, where the safety of materials is paramount.
The IEC 60695-11 standard is particularly important in the context of sustainable materials, as it helps identify which materials are most suitable for use in electrical devices that will be subjected to harsh environmental conditions. By ensuring that only compliant materials are used, manufacturers can contribute to reducing waste and promoting a circular economy.
For quality managers, compliance officers, R&D engineers, and procurement teams involved in the marine and ship equipment sector, understanding the intricacies of IEC 60695-11 is essential. This knowledge ensures that only materials with proven fire resistance are used, thereby enhancing safety standards across the industry.
The test setup typically includes a controlled environment chamber where the glow-wire flame test can be conducted accurately and consistently. The apparatus used for this purpose must adhere strictly to IEC 60695-11 specifications to ensure reliable results. Specimen preparation involves selecting representative samples of the material being tested, ensuring they are cut to standard dimensions.
The testing process itself is rigorous and standardized, providing precise data on ignition time and burn duration for each specimen. This detailed information allows manufacturers to make informed decisions about their product design and material selection, ultimately leading to safer and more reliable electrical equipment.
By adhering to IEC 60695-11 standards, companies can ensure that they meet regulatory requirements while also enhancing the safety and performance of their products. This standard is particularly valuable in sectors like marine and ship equipment manufacturing, where fire hazards are a significant concern.
In conclusion, IEC 60695-11 provides a critical framework for evaluating material flammability through controlled testing conditions. For those involved in the design and production of electrical equipment, particularly within sustainable materials applications, this test is an indispensable tool in ensuring high safety standards and regulatory compliance.

This is critical for preventing fires aboard ships, which can have devastating consequences not only for the crew but also for the environment.
Additionally, IEC 60695-11 testing is essential in the development and certification of sustainable materials used in electrical equipment. By ensuring that these materials meet stringent fire resistance requirements, manufacturers contribute to reducing the overall environmental impact of their products. This aligns with broader sustainability goals within the industry.
The test’s applicability extends beyond just shipboard applications; it is also relevant for other marine-related electrical systems such as offshore oil and gas platforms, maritime communications equipment, and navigation devices. In all these areas, ensuring that materials used in electrical components meet fire resistance standards is essential for operational safety and compliance with international regulations.
Furthermore, the IEC 60695-11 standard plays a crucial role in the certification process of new products entering the market. Regulatory bodies often require manufacturers to provide test results demonstrating that their materials comply with this standard before granting certifications. This ensures that all electrical equipment is manufactured using safe and reliable materials.
In summary, the IEC 60695-11 glow-wire flame test serves as a cornerstone for fire hazard evaluation in various sectors of the marine industry. Its ability to provide detailed insights into material flammability under controlled conditions makes it an indispensable tool for ensuring safety and compliance across this critical sector.
