What are the Russian GOST-R certification regulations and requirements for high-voltage electrical equipment with voltages exceeding 1 kV?
A detailed analysis of the Russian GOST-R certification regulations and requirements for high-voltage electrical equipment with voltages exceeding 1 kV, incorporating key information from search results:
I. Certification Regulations Basis
Mandatory Certification Requirements
According to Russian Government Decree No. 2425 (23 December 2021) and Decree No. 982 (1 December 2009), high-voltage electrical equipment with a voltage exceeding 1 kV (such as transformers, high-voltage switchgear, cables, etc.) must undergo GOST-R mandatory certification to be legally sold, imported, or manufactured in the Russian market.
Exceptions: High-voltage electrical equipment is not covered by the Customs Union EAC certification (CU-TR), so it cannot apply for an EAC certificate or declaration and must undergo Russian GOST-R certification.
Applicable standards  
High-voltage switchgear: Must comply with GOST 14693-90 (metal-clad equipment below 10kV) and GOST 1516.3-96 (insulation strength requirements for AC equipment from 1 to 750kV). 
Transformers: Must comply with GOST R 52719-2007, GOST 12.2.007.2-75, and other standards.
High-voltage cables: Must comply with GOST 24334-2020 (non-fixed installation cables) or GOST 31945-2012 (mining cables).
II. Certification Types and Processes
Certificate Types
GOST-R Declaration of Conformity (DoC): Applicable to medium-to-low-risk products (e.g., certain cables, transformers), self-declared by the importer or manufacturer without testing, with the same validity period as the CoC.
Application Process
Steps:
Submit the application form (in Russian/English) and technical documents (manuals, drawings, ISO 9001 certificate, etc.).
The certification body reviews the documents and may conduct sample testing (e.g., electrical performance, insulation testing) or factory inspections as needed.  
Issue the certificate and affix the GOST mark (to be displayed alongside the product nameplate).  
Duration: Typically 7–30 days; longer for complex products.  
III. Key Documents and Requirements  
Required Documents  
Business licence (Russian translation notarised)  
Product technical passport (including Russian manual, circuit diagrams)
ISO 9001 Quality Management System Certificate.  
Test reports (the process may be simplified if CE or IECEx certification is available).  
Language and Markings  
All documents must be in Russian, and product labels must include Cyrillic characters and the GOST-R mark.
IV. Important Notes  
Local Representative Requirements  
Non-Russian companies must apply through a legal entity within Russia (e.g., an importer or authorised agent).  
Continuous Compliance  
Annual surveillance audits are required during the certificate’s validity period (3/5-year certificates).  
Differences from Other Certifications  
GOST-R is limited to the Russian market. If access to other EAEU countries (e.g., Kazakhstan) is required, separate certification must be applied for.
5. Examples of Applicable Products  
Mandatory Certification Scope:  
High-voltage transformers, reactors, switchgear (1 kV and above).  
High-voltage cables (e.g., flexible cables for mining, fixed-installation cables below 35 kV).  
High-voltage current transformers, rectifiers.  
For specific product certification schemes, it is recommended to contact a Russian accredited body (e.g., Shanghai Jiheng Industrial) for the latest list and quotation.
