What is BS EN 61377-2:2016?

BS EN 61377-2:2016, also known as "Railway Applications - Rolling Stock Equipment - Shock and Vibration Testing - Part 2," is a technical standard developed by the European Committee for Electrotechnical Standardization (CENELEC). It provides guidelines and procedures for testing the shock and vibration resistance of rolling stock equipment used in railway applications.

Importance of BS EN 61377-2:2016

The main purpose of BS EN 61377-2:2016 is to ensure the safety and reliability of rolling stock equipment under various operating conditions. This standard helps manufacturers and operators evaluate the performance of their equipment and identify potential weaknesses or design flaws that need to be addressed. By conducting comprehensive shock and vibration tests, engineers can ensure that the equipment will withstand the demanding environments of railway operations.

Scope and Requirements

This standard covers a wide range of rolling stock equipment, including traction systems, auxiliary power supplies, control systems, passenger amenities, and more. It specifies the test methods, test levels, and acceptance criteria for evaluating the equipment's resilience to shock and vibration. The goal is to replicate the harsh operating conditions that rolling stock equipment may encounter during its lifetime, such as sudden impacts or continuous vibrations.

Testing Procedures

To comply with BS EN 61377-2:2016, manufacturers need to follow specific testing procedures. These typically involve subjecting the equipment to controlled shocks and vibrations using specialized equipment, such as shakers or impact hammers. The equipment's response to these stimuli is carefully monitored and measured to assess its performance. The standard provides detailed instructions on how to conduct these tests, including recommended test levels and durations.
