The International Electrotechnical Commission (IEC), the European Committee for Electrotechnical Standardization (EN), and the Aerospace Standard (AS) jointly developed a standard for vibration testing known as IEC/EN/AS 60068-2-6. This standard provides guidelines for the measurement and evaluation of mechanical vibrations in electrical and electronic equipment.
Importance of Vibration Testing
Vibration testing is crucial in assessing the durability, reliability, and performance of electrical and electronic equipment. During transportation, handling, or operation, these devices are often subjected to vibrations. It is vital to ensure that they can withstand such vibrations without any adverse effects on their functionality or structural integrity.
By subjecting the equipment to controlled vibrations, the test aims to identify potential weaknesses or vulnerabilities that may cause malfunctions or failures. Manufacturers can use the results to improve the product design, materials used, and manufacturing processes to enhance the device's resistance to vibrations.
Procedure and Requirements
IEC/EN/AS 60068-2-6 outlines the procedure and requirements for vibration testing. The test is typically conducted using either sinusoidal or random vibrations, depending on the intended application of the device being tested. Different types of vibrations, frequencies, and magnitudes are applied to simulate real-life conditions.
The standard specifies the criteria for evaluating the device's performance during and after the vibration test. These criteria may include acceptable levels of displacement, acceleration, and resonance frequency. Additionally, the standard defines various methods of measurement, including contact and non-contact approaches, to ensure accurate and reliable data collection.
Benefits and Applications
The benefits of adhering to IEC/EN/AS 60068-2-6 vibration testing are manifold. Firstly, it helps manufacturers produce more robust and durable products. By identifying weaknesses early in the development phase, potential failures or malfunctions can be minimized or prevented altogether.
Secondly, compliance with established vibration standards enhances customer satisfaction. End-users can have confidence in the reliability and performance of the devices they purchase, knowing that they have undergone rigorous testing for vibrations.
Furthermore, IEC/EN/AS 60068-2-6 facilitates international trade by establishing a common ground for evaluating vibration resistance. Manufacturers across different countries can refer to this standard to ensure their products meet global quality requirements. It promotes a fair and consistent assessment of vibrational resistance across the industry.
In conclusion, IEC/EN/AS 60068-2-6 is an essential standard in the field of vibration testing for electrical and electronic equipment. It sets forth guidelines and criteria for conducting these tests, ensuring the durability and reliability of these devices. By adhering to this standard, manufacturers can produce higher quality products, enhance customer satisfaction, and promote international trade.
