IEC 60695 2 11 Glow Wire Flammability Test for Electrical Devices
The IEC 60695-2-11 standard provides a method to determine the flammability of materials used in electrical and electronic devices. This glow wire test is particularly relevant when assessing the safety of components that may come into contact with heat or fire during normal operation.
The test involves placing a small sample of material on an electrically heated wire (glow wire). The temperature of this wire is gradually increased until it ignites the sample. The objective is to determine the lowest temperature at which the glow wire can ignite the sample, thus providing insights into the flammability characteristics of the material.
The IEC 60695-2-11 test is widely used in industries such as electronics manufacturing and electrical equipment design, ensuring that products are safe from fire hazards. It is particularly important for devices like power supplies, transformers, circuit boards, and other components that may be exposed to heat or flame.
The standard specifies detailed procedures for testing, including the dimensions of the glow wire, the heating rate, the temperature range, and the observation time after ignition. The apparatus used in this test typically includes a precision-controlled oven with a heated wire capable of reaching temperatures up to 850°C.
Material selection is crucial in ensuring product safety. By conducting IEC 60695-2-11 tests, manufacturers can identify materials that are prone to ignition and make informed decisions about the use of flame-retardant substances or alternative designs. This test also helps in complying with global regulations related to electrical safety.
The results of this test play a vital role in product development and quality assurance processes. Engineers can use these findings to refine their design choices, ensuring that products meet stringent safety standards without compromising performance.
It is important to note that the IEC 60695-2-11 glow wire test does not assess all aspects of flammability; it specifically targets the ignition temperature. For a comprehensive assessment of fire resistance, other tests like the vertical burn test (IEC 60695-2-12) may be required.
The implementation of this standard is crucial for industries that rely heavily on electronics and electrical devices. By adhering to IEC 60695-2-11, manufacturers can ensure the safety of their products in environments where fire hazards are present.
