PD ISO/TS 21826:2020

What is ISO 21826 about?  

ISO 21826 specifies a photometric titration method using EDTA for the determination of the total iron content of iron ores. 

This method applies to a concentration range of a mass fraction of 37,00 % to 72,00 % of total iron in natural iron ores, iron ore concentrates and agglomerates, including sinter products 

Who is ISO 21826 for?  

ISO 21826 on the determination of total iron content is beneficial for 

• Iron industry 
• Iron testing laboratories 
• Supplier and customers of iron ore 

Why should you use ISO 21826?  

EDTA is short for ethylenediaminetetraacetic acid. EDTA photometric titration method is used to determine the total iron content 

ISO 21826 provides guidance on apparatus, sampling and samples, test procedures, expression of results, test reports. 

With obedience and compliance to ISO 21826, you can efficiently perform EDTA photometric titration method and determine the total iron content in iron ore.
