Detailed Comparison and Analysis of Certification Requirements and Procedures for High-Voltage Electrical Equipment in Russia (GOST-R), Kazakhstan (GOST-K), and Kyrgyzstan (GOST-KG):
I. Russian GOST-R Certification
1. Regulatory Basis  
Mandatory certification scope: High-voltage electrical equipment with voltages exceeding 1 kV (such as transformers, high-voltage switchgear, cables, etc.) must undergo mandatory GOST-R certification, in accordance with Russian Government Decree No. 2425 (23 December 2021) and Decree No. 982 (1 December 2009).
Not applicable to EAC certification: High-voltage electrical equipment is not within the scope of the Customs Union EAC certification and must undergo GOST-R certification.
2. Certification Types  
GOST-R Certificate of Conformity (CoC): Requires laboratory testing + factory audit, valid for 1/3/5 years (5-year validity requires annual supervisory audits).  
GOST-R Declaration of Conformity (DoC): Self-declared by a Russian legal entity, no testing required, same validity period as CoC.
3. Key Standards  
High-voltage switchgear: GOST 14693-90 (below 10kV), GOST 1516.3-96 (insulation strength for 1-750kV).  
Transformers: GOST R 52719-2007, GOST 12.2.007.2-75, etc.
High-voltage cables: GOST 24334-2020 (non-fixed installation), GOST 31945-2012 (mining cables).
4. Process and Documents
Process: Application → Document review → Sample testing (if required) → Factory inspection (if applicable) → Certification issuance.  
Documents: Russian application form, ISO 9001 certificate, technical documents (manuals, drawings), test reports (e.g., CE/IECEx).  
5. Labeling Requirements  
Products must be affixed with the GOST-R mark (minimum 5 mm) and Russian-language information.
II. Kazakhstan GOST-K Certification  
1. Regulatory Basis  
Mandatory certification scope: High-voltage electrical equipment must comply with GOST-K standards and Eurasian Economic Union technical regulations (e.g., TR CU 004/2011 on the safety of low-voltage equipment).  
Relationship with EAC certification: Some high-voltage equipment may need to meet both GOST-K and EAC certification requirements.
2. Certification Types  
GOST-K Certificate of Conformity (CoC): Requires laboratory testing + factory audit, valid for 1–5 years.  
GOST-K Declaration of Conformity (DoC): Applicable to medium-to-low-risk products, requires technical documentation support.  
3. Key Standards  
Electrical Safety: GOST 12.1.019-79 (overload protection, grounding requirements).
Explosion-proof equipment: GOST 12.1.010-76 (petrochemical industry).  
4. Process and Documents  
Process: Application → Document review → Local laboratory testing → Factory inspection (if applicable) → Certificate issuance.  
Documents: Russian/Kazakh application form, ISO 9001 certificate, technical documentation, test reports.
5. Labeling Requirements  
Product labels must include the GOST-K mark and Russian/Kazakh language information.  
III. Kyrgyzstan GOST-KG Certification  
1. Regulatory Basis  
Mandatory certification scope: High-voltage electrical equipment must comply with GOST-KG standards and Eurasian Economic Union technical regulations (e.g., TR CU 004/2011).
Relationship with EAC certification: Some products must also apply for EAC certification (e.g., TR CU 032/2013 Safety of High-Voltage Equipment).  
2. Certification Types  
GOST-KG Certificate of Conformity (CoC): Requires sample testing + factory audit, valid for 1–5 years.  
GOST-KG Declaration: Some products may be self-declared, but high-voltage electrical equipment typically requires mandatory certification.
3. Key Standards  
High-voltage equipment: References the IEC 62271 series standards (high-voltage switchgear).  
Grid parameters: Must match local grid specifications (220V/50Hz single-phase, 380V/50Hz three-phase).  
4. Process and Documentation  
Process: Application → Testing (local or mutually recognised laboratory) → Factory inspection (if applicable) → Certificate issuance.
Documents: Russian/Kyrgyz technical documents, ISO 9001 certificate, CE/GOST-R test reports (simplified process available).
5. Labeling Requirements  
Must affix the GOST-KG mark and Russian/Kyrgyz language labels.

V. Recommendations
Plan Ahead: The certification process for high-voltage electrical equipment is lengthy (typically 1-3 months), so sufficient time should be allocated.
Local Agent: All three countries require applications to be submitted through a local legal entity or authorised representative.  
Document Translation: All technical documents must be translated into the local official language.  
Testing Recognition: Existing CE/IECEx/GOST-R test reports can reduce the need for duplicate testing.  
For specific product certification solutions, it is recommended to contact a professional institution (such as Shanghai Jinghe Industrial) for customised services.
