Pressure equipment CU-TR certification (also known as EAC Certification) is a mandatory conformity assessment for pressure equipment entering the Eurasian Economic Union (EAEU) market (Russia, Belarus, Kazakhstan, Armenia, Kyrgyzstan). Here’s a structured overview:
🔍 1. Applicable Regulation & Scope
Core Regulation: TR CU 032/2013 ("On the Safety of Equipment Operating Under Overpressure") governs pressure vessels, boilers, pipelines, valves, and safety accessories.
Scope:
Equipment with maximum allowable pressure > 0.05 MPa.
Categorizes equipment into four risk classes (1–4, with 4 being highest risk) based on media hazard, pressure-volume product, and temperature.
⚖️ 2. Certification Type by Risk Class
Risk Class    Media Group    Certification Type
1–2    Non-hazardous (Group 2, e.g., water/air)    EAC Declaration (DoC)
3–4    Hazardous (Group 1, e.g., flammable/toxic)    EAC Certificate (CoC)
💡 Key Difference:
CoC: Issued by EAEU-accredited bodies; requires lab tests, factory audits, and material sampling.
DoC: Self-declaration by local importer; relies on technical documentation review.
📑 3. Required Documentation
Technical specifications (design drawings, material lists).
Risk assessment reports and safety analyses.
Test reports from EAEU-accredited labs (e.g., mechanical strength, leak tests).
Quality management certificates (ISO 9001 recommended).
User manuals and labels in Russian or EAEU languages.
For foreign manufacturers: Authorization letter to a local EAEU representative.
⚙️ 4. Certification Process
1.Classify Equipment: Determine risk class per TR CU 032.
2.Testing: Samples tested for safety, pressure resistance, and material compliance (e.g., GOST 34347-2017).
3.Factory Audit (for CoC): EAEU experts inspect production facilities and quality systems.
4.Document Review: Certification body evaluates technical files.
5.Certification Issuance:
Validity: Up to 5 years for series production; single shipment for one-time imports.
⚠️ 5. Key Technical Requirements
Material Standards: Compliance with GOST norms (e.g., GOST 34347-2017 for design, GOST 34233 for strength calculations).
Safety Margins:
Yield strength safety factor ≥1.5 (per CU-TR 032).
Tensile strength safety factor ≥2.4.
Testing & Inspection:
100% RT/UT for Class 1–2 equipment; 15–50% for lower classes.
Hardness testing for welds (e.g., ≤220 HB for chromium-molybdenum steel).
💰 6. Cost & Timeline
Costs:
CoC: $3,000–$15,000 (varies by complexity and validity).
DoC: $1,000–$5,000.
Timeline:
CoC: 2–4 months (including audits and testing).
DoC: 1–2 weeks.
✅ 7. Post-Certification Obligations
Annual factory surveillance audits for multi-year CoC.
Mandatory EAC marking on equipment/packaging (min. 5 mm).
Compliance with updates to TR CU 032 (e.g., 2024 flame-retardant rules).
💡 Recommendations
Partner with EAEU-authorized labs (e.g., in Russia/Kazakhstan) for efficient testing.
Pre-verify material compliance (e.g., S/P content limits in GOST 5520-2017).
Use local representatives to navigate bureaucracy and language barriers.
