NF EN 60216 Heat Resistance Materials Testing for Automotive Plastics
The NF EN 60216 standard is a crucial component in the automotive industry, specifically targeting materials used in plastics. This test evaluates the heat resistance of plastics under specified conditions to ensure they can withstand high-temperature environments without degrading or failing.
Heat resistance testing is essential for ensuring that plastic components meet safety and performance requirements in various automotive applications. These tests are conducted on a range of materials, including thermoplastics, thermosetting plastics, and composite materials used in engine covers, fuel tanks, and other critical parts.
The NF EN 60216 standard specifies the apparatus and procedures for determining the heat resistance of electrically insulating materials by means of a hot-air test. The testing process involves exposing specimens to controlled temperatures over time, monitoring their behavior, and assessing any changes in properties such as mechanical strength, dimensional stability, and electrical performance.
Understanding the heat resistance properties is vital for the automotive industry because it ensures that plastics can function effectively under extreme environmental conditions. This includes high ambient temperatures during operation, exposure to engine exhaust gases, and other factors that could lead to material degradation.
The testing process outlined in NF EN 60216 involves several key steps: - Specimen preparation: The materials are cut into standard dimensions specified by the standard. - Conditioning: Specimens are conditioned at room temperature for a minimum of 48 hours before testing. - Testing conditions: Specimens are exposed to hot air under controlled conditions, typically in an oven or similar apparatus. - Data collection: Temperature and time parameters are recorded during the test. Physical and mechanical properties are measured periodically. - Evaluation: The results are compared against specified criteria to determine compliance with NF EN 60216.
Compliance with this standard ensures that automotive plastics can withstand high temperatures without compromising their integrity, thus enhancing vehicle safety and performance. This is particularly important for components that are exposed to heat sources or engine exhaust gases.

Why It Matters
The heat resistance testing of automotive plastics is critical for ensuring the reliability and safety of vehicles. By adhering to NF EN 60216, manufacturers can ensure that their plastic components will perform optimally under extreme conditions. This not only enhances vehicle performance but also contributes to overall road safety.
Heat resistance testing helps identify potential issues with materials early in the development process, allowing for necessary adjustments and improvements before mass production. This proactive approach ensures that any shortcomings are addressed before they impact the end product.
In addition, compliance with this standard is often a requirement for meeting broader regulatory standards in the automotive industry, such as those set by international organizations like the Society of Automotive Engineers (SAE) and the International Organization for Standardization (ISO).
Benefits
- Ensures that plastic components can withstand high temperatures without degrading.
