Environmental Testing IEC 61373 : 2010

IEC 61373:2010 | Railway applications – Rolling stock equipment – Shock and vibration tests (Note: This standard is often required in conjunction with EN 50155 for electronic equipment on rolling stock.)

This standard covers virtually any electromechanical or electronic component mounted on a train. We categorize products based on their mounting location, as the vibration intensity increases significantly closer to the track:

• Category 1 (Body Mounted): Equipment fixed to the coach body (e.g., Passenger Information Systems, lighting, control panels).
• Class A: Cubicles/Amalgamations.
• Class B: Direct mounting.
• Category 2 (Bogie Mounted): Equipment attached to the wheel truck frame (e.g., sensors, braking units).
• Category 3 (Axle Mounted): Components directly on the wheelset (high-vibration environment).

To certify compliance, the Equipment Under Test (EUT) must endure a three-stage rigorous testing protocol across all three axes (Vertical, Transverse, and Longitudinal):

1. Functional Random Vibration: The device is powered on and tested at service levels to ensure no signal interruption or malfunction occurs.
2. Simulated Long-Life Testing: An accelerated fatigue test (non-operational) using increased vibration levels to simulate the equipment’s entire life cycle in a short duration.
3. Shock Testing: High-impact half-sine pulses to simulate shunting jolts or emergency braking, ensuring mechanical mounts do not shear or loosen.

All testing is conducted under a strict quality management system. The reports generated are fully accredited by NABL (ISO/IEC 17025) and recognized by ILAC, ensuring they are accepted by Indian Railways, Metro Rail Corporations, and international rolling stock manufacturers (OEMs).

We understand that project deadlines are often tight.

• Standard Testing Duration: 3 to 5 working days (depending on the number of axes and functional monitoring complexity).
• Report Issuance: 2 to 3 working days post-testing.

To ensure a smooth testing process without delays, the following items are required:

• One (1) Fully Functional Unit: The device must be production-ready.
• Mounting Accessories: All brackets, bolts, and fasteners intended for actual installation must be provided.
• Mating Connectors/Cables: Required for functional monitoring during the test.

Note: If a specialized mounting fixture is required to secure your product to the vibration shaker, please consult with us beforehand.

Pricing for IEC 61373 testing is custom-quoted based on:

1. Weight and Dimensions: Heavier items require larger electro-dynamic shakers.
2. Fixture Fabrication: Whether a custom jig needs to be designed to hold the sample.
3. Functional Monitoring: The complexity of monitoring the device (live power/data) during the test.

For the final test report to be valid and complete, please provide:

• General Arrangement (GA) Drawing.
• Bill of Materials (BOM) or Product Datasheet.
• Weight and dimensions of the unit.
• ISO 9001 Certificate of the manufacturer (if applicable).
• User Manual regarding mounting instructions.
