EN 60695-11-20 Fire Hazard Testing of Plastics – Glow Wire Ignition Temperature
The CEN standard EN 60695-11-20 specifies the method for determining the glow wire ignition temperature (GWIT) of plastics. This test evaluates the material's resistance to combustion under controlled conditions, which is crucial for ensuring that materials used in electrical and electronic equipment do not ignite or sustain flame when exposed to a glowing hot wire.
The GWIT test involves heating a fine tungsten wire to a specified temperature, typically around 650°C. A small specimen of the plastic material under test is then placed adjacent to this wire. If the specimen ignites and burns after being exposed for 10 seconds, the test is repeated at an incrementally higher temperature until ignition occurs again. The lowest temperature at which the material ignites is recorded as its GWIT value.
The GWIT test is critical in assessing the fire safety of plastic components used in electrical devices such as household appliances, medical equipment, and automotive parts. It helps manufacturers ensure compliance with various national and international standards aimed at reducing fire hazards in consumer products.
For accurate and reliable testing, it's essential to follow precise specimen preparation methods. Specimens should be cut from the actual product or a representative sample of the material, avoiding any defects such as cracks or impurities that could affect test results. The specimens must also be conditioned according to the standard before testing.
The instrumentation used in this test includes a Glow Wire Furnace (GWF) and an automated data acquisition system. The GWF heats the tungsten wire to the specified temperature, ensuring consistent heating conditions across all samples. Automated systems help maintain accurate recording of temperatures and ignition times, reducing human error.
Compliance with EN 60695-11-20 is essential for manufacturers aiming to meet strict fire safety regulations in Europe and other regions that recognize this standard. Compliance ensures product safety, reduces the risk of fires, and protects consumers from potential harm.
The test results provide critical data that helps quality managers and compliance officers make informed decisions about material selection and design changes. By understanding the GWIT value of different materials, manufacturers can optimize their products to meet both functional requirements and stringent fire safety standards.
Additionally, this testing contributes to broader environmental goals by promoting safer and more sustainable manufacturing practices. By selecting materials with higher GWIT values, manufacturers reduce the risk of accidental fires, which can lead to lower insurance premiums and reduced liability costs. This not only benefits individual companies but also supports a safer environment for all.
- Reduces fire risks: Ensures that plastic components in electrical equipment do not ignite or sustain flame under specified conditions.
- Enhances product reliability: Guarantees consistent performance and safety of products across different environments and usage scenarios.
- Sustains environmental benefits: Minimizes the potential for accidental fires, which can lead to reduced emissions from firefighting efforts and lower carbon footprints.
The GWIT test is a vital tool in ensuring that plastics used in electrical applications are safe and reliable. By adhering to this standard, manufacturers contribute to both product safety and environmental sustainability.
