EAC Certificate for Combustible Natural Gas

On June 29, 2023, the official publication of Decision No. 87/2023 by the Board of the Eurasian Economic Commission (EEC) took place, dated June 27, 2023.

This decision includes significant changes to the list of EAC standards, EAC rules, and EAC testing procedures necessary to meet the requirements of Technical Regulations TR CU/EAEU of the Eurasian Economic Union (EAEU States).

Update of TR EEU 046/2018  

These updates have direct implications for compliance with the requirements and EAC standards related to combustible natural gas in the Eurasian Economic Union. The list of standards titled "Safety Regulations for the Transportation and Use of Combustible Natural Gas" is governed by TR EAEU 046/2018.

The document will become legally effective after its official publication following a period of 6 months. These groundbreaking changes relate to the update of a list that was already established by the previous decision of the EAEU Collegium No. 112 dated August 13, 2021. 

These measures aim to adapt the existing foundations for the EAC certification of combustible natural gas in accordance with the regulations of Technical Regulation TR EAEU 046/2018 to modern requirements.

Update of GOST Standards

The upcoming release of the updated EAC Standards and GOST Standards will encompass a total of 248 standards, while the current nomenclature contains 275 standards. Throughout the current year, some GOST standards will lose their validity. 

At the same time, application years 2025 and 2026 will be established for selected EAC standards in the updated list. This update aims to achieve an advanced alignment with the standards landscape, thereby optimally meeting current requirements.

EAC Standards of TR EEU 046/2018

The structure of the TR CU 046/2018 directory remains unchanged and continues to be grouped by EAC standards according to gas indicators.

The listed indicators include:

  • Calculated Methane Number
  • Relative Density Compared to Air
  • Mass Concentration of Hydrogen Sulfide
  • Molar Share of Non-Combustible Components
  • Mass Concentration of Mercaptan Sulfur
  • Molar Share of Oxygen

It is particularly noteworthy that TR EAEU TR 046/2018 successfully came into force on January 1, 2022, making the implementation of declarations of conformity prior to the market introduction of products a mandatory requirement. This ensures compliance with EAC regulations.

What is the purpose of the update of the EAC standards for combustible natural gas?
The update of the EAC standards for combustible natural gas aims to adapt the existing foundations of EAC certification to the modern requirements of the Technical Regulations TR EAEU 046/2018. This is intended to enhance safety and efficiency in the transportation and use of combustible natural gas.
When does the updated document come into effect?
The updated document will come into effect six months after its official publication. The publication date was June 29, 2023, which means that the document will become legally binding at the end of December 2023.
What changes are there in the GOST standards?
Some GOST standards will lose their validity over the course of the year, while the updated list of EAC standards will include 248 standards, compared to the current 275 standards. For selected EAC standards, the application years 2025 and 2026 are planned to meet current requirements.
How does the update affect the EAC certification of natural gas?
The update makes the issuance of declarations of conformity prior to the market introduction of products a mandatory requirement, ensuring compliance with EAC regulations and enhancing safety in the handling of combustible natural gas.
Are the indicators in the TR CU 046/2018 directory being changed?
No, the structure of the TR CU 046/2018 directory and the listed indicators remain unchanged. These include the calculated methane number, the relative density compared to air, the mass concentration of hydrogen sulfide, the molar fraction of non-combustible components, the mass concentration of mercaptan sulfur, and the molar fraction of oxygen.
