Biogas Fermentation Tank (Anaerobic Reactor) CUTR Certification (EAC Certification)
1. Applicable Regulations  
Compliance with TR CU 032/2013 ‘Technical Regulations on the Safety of Pressure Equipment’ is required. This is a mandatory certification (high-risk equipment requires factory audit + sample testing).
2. Certification Types  
CU-TR Certificate of Conformity (CoC): Requires testing by an EAEU-accredited laboratory (e.g., strength, sealing), plus factory audit, applicable to high-risk equipment.  
CU-TR Declaration of Conformity (DoC): Self-declared compliance by the manufacturer, applicable to low-risk equipment (technical documents and test reports must be provided).
3. Key Technical Requirements  
Material and Structure: The tank body should preferably be made of carbon steel (compliant with the NB/T 47003.1 standard), with consideration for corrosion allowance; insulation materials may include polystyrene foam, etc.
Safety Devices: Must be equipped with flammable gas/toxic gas detection and alarm devices, metal explosion-proof discs, and lightning protection grounding devices.  
Operation and Maintenance: Must be equipped with ladders and maintenance platforms, with maintenance access ports (diameter ≥ 300 mm) at the bottom and top, and provide operating manuals and maintenance instructions.  
4. Certification Process  
Determine Product Category: Confirm the applicable certification scheme (e.g., 1C, 2C, etc.) based on the customs code (HS Code). .  
Prepare Documents: Include technical drawings, strength calculation documents, welding procedure qualification, material certificates, and test reports (e.g., pressure tests, leakage tests).
Submit application: Submit the application to an EAEU certification body (e.g., Russian GOST-R Certification Centre, Shanghai Jinghe Industrial Equipment Testing Co., Ltd.), including the application form, technical documents, and test reports.  
Factory audit (if applicable): High-risk products require an audit of production equipment, quality control systems, and welding processes.  
Issue certificate: Upon approval, an EAC Certificate of Conformity is issued, valid for 1–5 years, and the EAC mark must be affixed to the product.
5. Notes  
Manufacturers from non-EAEU member states must designate a local representative (e.g., a Russian or Kazakhstani company) to handle certification applications and subsequent oversight.  
Certificates must be registered on the EAEU official platform to ensure traceability.  
Certification body: Shanghai Jinghe Industrial Equipment Testing Co., Ltd. specialises in product certification and testing for Russia and EAEU member states and serves as the Chinese representative office of the Russian Testing and Certification Group.
