Escopo e aplicabilidade

This standard applies to the classification and quality testing of purified civil coalbed methane (coal mine gas). It covers gas used as fuel in residential, commercial (public building), and other non-industrial sectors. This standard is mandatory for manufacturers and distributors supplying coalbed methane to the Chinese civilian market.

Requisitos técnicos

The standard classifies civil coalbed methane into four categories (Class I, II, III, and IV) based primarily on the methane mole fraction, which must not be lower than 30%. It specifies limits for gross calorific value, total sulfur, hydrogen sulfide, particulate matter, and carbon dioxide mole fraction. The gas must undergo purification treatment, and the particulate matter content must comply with the specified limits. Additionally, the standard mandates odorization of the gas to ensure that leaks are detectable by a person with a normal sense of smell when the methane volume fraction reaches 1%. The odorant must comply with the requirements of GB 55009.

Métodos de ensaio

Testing procedures involve sampling according to GB/T 13609. Methane and carbon dioxide mole fractions are determined via gas chromatography (GB/T 13610). Gross calorific value is calculated using GB/T 11062 or GB/T 12206. Sulfur compounds (total sulfur and hydrogen sulfide) are measured using various methods from the GB/T 11060 series. Particulate matter is determined by the gravimetric method (GB/T 27893), and the water dew point is measured using GB/T 17283.1 or SY/T 6899.

Perguntas frequentes

What products are regulated under GB 26569-2026?

It regulates purified civil coalbed methane (coal mine gas) used as fuel in residential, commercial, and other non-industrial sectors.

Are there any updates from the previous version of GB 26569?

Yes, the 2026 version adds requirements for carbon dioxide and particulate matter content, changes testing methods for total sulfur, hydrogen sulfide, and water dew point, and updates the factory inspection rules.

Is odorization mandatory for civil coalbed methane under this standard?

Yes, the gas must be odorized to ensure detectability when the methane volume fraction reaches 1%. The odorant must meet the requirements of GB 55009.
