Updated Work Program of the ISS NTC H193 – Natural Gas

The ISS NTC KS H193, Natural Gas, has updated its Work Program for the next five years. Although a work program is no longer a mandatory document in international and European standardization, NTC members recognized the importance of strategic planning and prepared a comprehensive document that serves as a clear roadmap for the further development of standardization in this field.

Mileva Cvetković, an employee of the Energy Agency of the Republic of Serbia who chairs the NTC H193, alongside NTC Secretary Branka Tomašević from the Institute for Standardization of Serbia and other NTC H193 members, prepared this document, which is significant for the entire natural gas sector.

Scope of the NTC H193 Work

The NTC H193 deals with standardization in the following areas:

Natural gas and natural gas substitutes (gaseous fuels, including biogas, biomethane, coalbed methane, shale gas, and wet gas);
Terminology and quality specifications;
Methods of measurement, sampling, analysis, and testing;
All stages of the supply chain—from production to delivery to users domestically and abroad;
Specifications for natural gas and biomethane as fuel;
Biomethane injected into natural gas pipelines;
Gas analysis, including gas mixtures, sampling, transfer lines, analytical methods, and performance evaluation of analyzers.

Current activities of the NTC H193

A meeting of the NTC H193 was held yesterday at the ISS premises to discuss the draft standard nkSRPS EN ISO 19739:2026, Natural gas — Determination of sulfur compounds by gas chromatography (identical to ISO 19739:2004).

This standard is being adopted in the Serbian language for the first time. This second meeting, dedicated to the adoption of the translation of this significant document, took place in a productive and constructive atmosphere.

The updated Work Program represents an important step toward improving the quality, safety, and reliability of the natural gas system in the Republic of Serbia, as well as ensuring alignment with international and European standards.
