CETEST - Test & Analysis Centre is your number one test department. Fully accredited, we are experts in testing with over 40 years of experience in the railway sector. Our offering covers a wide variety of component test benches at our facilities combined with a global on-track measurement deployment capacity, helping customers all over the world test rail products and systems.
From validation and verification testing in the development phase to product homologation and also failure detection / root cause analysis in the after-sales operation, at CETEST we can assist you during the full lifecycle of your product.
We are experts in instrumentation, measurement and control, providing testing according to international standards, as well as fully tailor-made solutions. Our test and instrumentation capacity is very diverse.
Structural integrity and fatigue testing
Verification and validation structures from car bodies (EN 12663, APTA, etc), bogie frames (EN 13479, UIC 514-4 and UIC 614-4, etc) and bolsters to crash energy management systems, we carry out quasistatic and dynamic / fatigue testing, as well as non-destructive inspection.
Rotating elements testing
CETEST carries out verification and validation of wheels, axles (EN 13260, EN 13261, EN 13262) and bearings (EN 12082), as well as functional testing of gearboxes and motors.
Dynamic behaviour testing
CETEST offers static suspension characterisation for full vehicles, including wheel equalisation, suspension flexibility, carbody / bogie rotational resistance, as well as vehicle centre of gravity determination.
CETEST also offers on-track dynamic testing for checking vehicle stability, safety against derailment, track fatigue and comfort characteristics. We measure vehicle dynamic behaviour from simple ride quality measurements to full complete rail / wheel interaction studies (EN 14363, UIC 518, US CFR 49, EN 12299, ISO 2631, etc).
Noise and vibration measurement
CETEST can offer customers static and dynamics evaluation for all components, as well as for full vehicles, from single point vibration evaluation to complex multicomponent modal analysis and combined noise and vibration correlation studies (ISO 3381, ISO 3095, TSI 1304/2014, IEC 60268-16 etc).
Electro magnetic compatibility and energy consumption measurement
Electro magnetic compatibility related measurement is one of our core activities. We perform verification and validation of full vehicles, as well as components. We are also active in energy consumption measurement and control (EN 50121, EN 50238).
We provide our own proprietary patented advanced technology for instrumented wheel sets with an offering that goes from one-time test services for homologation to full turnkey systems. It is a sensing system capable of measuring, in an uncoupled manner, the contact forces associated to the wheel/rail interaction, offering unique performance and accuracy, thanks to calibration and verification made in both static and rolling conditions. The technology is tested in different vehicle types and at speeds that exceed 350km/h.
We also perform instrumented pantograph. The system is able to accurately measure contact forces and includes Pitot tubes for wind profile characterisation over the vehicle and high-speed cameras for the study of arching phenomena (EN 50317, EN 50367, TSI RSHS, TSI Energy, etc).
For all vehicle manufacturers and suppliers, we provide services that cover homologation needs, design verification testing, research-related testing and after-sales testing support. Our customers include:
- Passenger vehicle manufacturers
- Special track vehicle manufacturers
- Component suppliers
We are also very active in the testing related to operations improvement. We perform measurements targeted at design modifications, as well as failure detection and root cause analysis. We perform measurements at the tracks and on the vehicles of:
- Rail operators
- Infrastructure managers
Additionally, we work closely with other railway organisations, namely:
- Notified bodies
- Engineering firms
Portable test rigs and global deployment capacity
CETEST offers a unique capacity in the railway sector with a series of portable test rigs that we can bring to our customers, helping them avoid the extra cost and effort of shipping large components or even full vehicles to an external laboratory.
Instead, CETEST brings the laboratory to you with full control of the test performance, minimising costs and risks. Our field testing deployment is global and very fast and our staff can perform testing in several continents simultaneously with full quality and best service.
Experience, quality and flexible service
Our team is composed of engineers and skilled technicians with a diverse variety of origins, including railways, aerospace, renewable energy, automotive industries and researchers from academia.
We provide first-class testing services with maximum quality, always following international standards but adding strict internal quality procedures to ensure best delivery to our customers.
All services are provided with a high level of flexibility, adapting to customer needs in terms of planning, timing and budget constraints.
About CETEST, fully accredited laboratory
CETEST is an independent test centre, which is ISO 17025 accredited to perform testing according to European and other international standards. This means that all testing conducted under the framework of ISO 17025 correctly follows pertinent standards and therefore guarantees full compliance before national authorities. CETEST is also ISO 9001, ISO 14001 and EN 9712 accredited.
We also have recognition from, have worked with and been evaluated by safety authorities, notified bodies and independent experts from several countries, including Germany, France, Brazil, the UK, Belgium, Spain, India, Italy and the US.
