Summary of EN 61373 Compliance Testing
This environmental testing standard covers the requirements for random vibration and operational shock testing items. The EN test is only to demonstrate the ability of the equipment under test to withstand the type of environmental vibration conditions normally expected for railway vehicles.
This standard, however, is not intended to cover self-induced vibrations as these will be specific to particular applications.
Simulated long-life testing is achieved in multiple different ways. Each having their associated advantages and disadvantages. The following below is the most common:
- Amplification: Where the amplitudes are increased and the time base decreased.
- Time compression: Where the amplitude history is retained and the time base is decreased.
- Decimation: Where time slices of the historical data are removed when the amplitudes are below a specified threshold value.
This standard’s primary concern is with railway vehicles on a fixed rail system. However, its wider use is not precluded. For systems operating on pneumatic tyres, or other transportation systems such as trolleybuses, the supplier and customer must agree on the test levels at the tender stage.
EN 61373 Section 8 Increased Random Vibration Testing
The environmental equipment under testing is tested with the relevant r.m.s. value and frequency range given in the table below. When the orientation is unknown, the test is carried out in the three axes with the r.m.s. value given for the vertical axis.
The duration of the functional vibration test is allowed sufficient time for all the specified functions to be completed.
The functional tests agreed with the customer are carried out during functional random vibration testing.
Expert EN 61373 Section 8 Environmental Product Testing
Our team strives to give our customers more time and energy on product development instead of testing. Keystone has a full lab of test equipment which permits us to provide short lead times on scheduling. In addition to environmental vibration testing, Keystone has a full scope of expertise including rain, solar radiation, humidity, and pyroshock.
