EN 50155 Vibration Materials Testing of Electronic Components
The EN 50155 standard is a critical component in the automotive industry, ensuring that electronic components are robust and reliable under the harsh environmental conditions they may encounter during vehicle operation. This service focuses on vibration testing according to EN 50155, which is essential for verifying the durability of electronic assemblies used in modern automobiles.
The standard applies specifically to passenger cars, light commercial vehicles, motorcycles, mopeds, and bicycles. It provides a framework for assessing the performance of electronic components under various environmental conditions, including vibration, temperature cycling, and humidity exposure. Vibration testing is one of the most critical aspects as it simulates the dynamic forces that these devices experience during vehicle operation.
The primary objective of EN 50155 vibration materials testing is to ensure that the electronic assemblies can withstand the vibrations generated by the vehicle’s engine and drivetrain. These vibrations are not only present in the operating environment but also during manufacturing, transportation, and maintenance phases. By simulating these conditions, manufacturers can identify potential failure points early in the development process.
The testing procedure involves subjecting the electronic components to a range of frequencies and amplitudes, typically within the ranges specified by EN 50155. The test setup includes specialized vibration tables that are capable of generating controlled levels of oscillation. This allows for precise control over the parameters such as frequency, amplitude, and duration.
One of the key aspects of this testing is the preparation of the specimens. Prior to testing, the electronic assemblies must be prepared according to strict guidelines provided in EN 50155. This includes ensuring that all connections are secure, the components are mounted correctly, and any external factors such as packaging or shielding do not interfere with the test results.
The instrumentation used for this testing is state-of-the-art equipment designed specifically for automotive applications. The vibration tables are equipped with sensors capable of measuring displacement, velocity, and acceleration at multiple points on the specimen. This data is crucial for understanding how different parts of the assembly respond to the applied vibrations.
After the test, the specimens undergo a thorough inspection to identify any signs of damage or failure. Common indicators include cracks in the solder joints, delamination of the PCB (Printed Circuit Board), or changes in component dimensions that could affect functionality. The results are then documented and reported according to EN 50155 standards.
EN 50155 vibration materials testing is particularly important for ensuring compliance with international regulations and industry best practices. By adhering to this standard, manufacturers can demonstrate their commitment to quality and reliability, which is essential in the highly competitive automotive market.
Applied Standards
In addition to EN 50155, several other standards may be relevant depending on the specific requirements of the testing. These include:
- ASTM E493 - This standard provides guidelines for determining the fatigue life of materials under cyclic loading.
- ISO 16750-2 - This part of ISO 16750 series specifies environmental conditions and test procedures for electronic components in road vehicles, including vibration testing.
- EN 384 - While not specifically focused on vibration, this standard covers the general requirements for electrical equipment used in passenger cars, which can influence how components are tested under EN 50155.
The application of these standards ensures that the testing aligns with international best practices and is consistent with global industry expectations.
