BS ISO 925:2019

What is ISO 925- Determination of carbonate carbon content using gravimetric method about?  

ISO 925 specifies a gravimetric method of determining the carbon in the mineral carbonates associated with solid mineral fuels. 

The result obtained will include any carbon from atmospheric carbon dioxide absorbed by the fuel. 

Who is ISO 925- Determination of carbonate carbon content using gravimetric method for? 

ISO 925 on determination of carbonate carbon content using gravimetric method is useful for: 

• Thermal power plants 
• Department of fuel characterization 
• Laboratories and testing houses 

Why should you use ISO 925- Determination of carbonate carbon content using gravimetric method? 

Determination of carbonate carbon content in solid mineral fuels is very vital because heat value is dependent on such combustible content.  

In solid mineral fuels, carbon is found alone or bound in the form of compounds such as carbonate carbon, which gets generated from absorbed carbon dioxide from atmosphere. 

ISO 925 provides guidance on determining carbonate carbon content using gravimetric method with precision and accuracy.
