TR CU 003/2011 On the Safety of Railway Infrastructure EAC Certification
Regulatory Overview
TR CU 003/2011 is a Customs Union technical regulation aimed at ensuring the safety of railway infrastructure. This regulation was established by the Eurasian Economic Union (EAEU) to harmonise safety standards across member states in the field of railway infrastructure and applies to EAEU member states such as Kazakhstan. Its purpose is to ensure the safe and efficient operation of railway transportation and reduce accidents and risks caused by railway infrastructure issues.

Meaning of EAC Certification
EAC certification, or Eurasian Economic Union Conformity Certification, is a mandatory certification system. Products and services related to railway infrastructure safety must obtain EAC certification to demonstrate compliance with the requirements of TR CU 003/2011 before they can be circulated and used within the Eurasian Economic Union market.

Scope of Certification
Railway tracks and related components: including rails, switches, sleepers, etc. The quality and safety of these components directly impact train operational safety. For example, the material, strength, and flatness of rails must meet the standards specified in the regulations.
Signalling systems: such as railway signal lights, switch control systems, etc. Signalling systems are critical for maintaining train operational order and safety, with reliability and accuracy being of utmost importance.
Communication equipment: Communication equipment used for communication between trains and dispatch centres or stations, such as wireless communication systems and train positioning systems, ensuring timely and accurate information transmission.
Power supply systems: Including overhead contact lines and substations, which provide stable power supply to trains. Their safety and stability play a critical role in the normal operation of railway transportation.
Certification Process
Submit Application
The company must submit a certification application to the certification body, along with detailed information about the product or service, such as technical specifications, design drawings, and production processes, to enable the certification body to understand the product's specifics.

Product Testing
The certification body will conduct a series of tests on the product being certified, with test items determined based on the product's type and characteristics. For example, track strength tests or signal system functionality tests may be conducted to ensure the product complies with regulatory requirements.

Factory Audit (if applicable)  
For some manufacturing companies, the certification body may conduct a factory audit to verify whether the company's production management system, quality control system, etc., can ensure that the product consistently meets regulatory standards. The audit covers aspects such as production equipment, personnel qualifications, and raw material management.

Certificate Issuance
If the product passes the tests and audit, the certification body will issue an EAC certification certificate. Products that obtain the certificate may display the EAC certification mark on the product or packaging, indicating compliance with the requirements of TR CU 003/2011.

Significance of Certification
Ensuring Safety: Through rigorous certification procedures, the safety of railway infrastructure is ensured, reducing the occurrence of railway accidents and safeguarding the transportation safety of passengers and goods.
Promoting Trade: Unified certification standards eliminate technical trade barriers between member states, enabling railway infrastructure products to circulate freely within the Eurasian Economic Union market and fostering regional trade development.
Enhancing Quality: Encouraging enterprises to continuously improve product and service quality by adopting advanced technologies and management methods to meet regulatory requirements and market demands.
