Application

The Standard Reference Material (SRM) is primarily intended for evaluating analytical methods used to classify coal fly ash and to determine the constituent elements in coal fly ash or similar matrix.

Features and Benefits

  • Certified mass fraction values for major and minor constituent elements are traceable to NIST’s realization of the SI unit of the kilogram and expressed as a percentage.
  • Reference mass fraction values are traceable to NIST’s realization of the SI unit of the kilogram and calculated as a mass fraction and expressed as a percentage.
  • Information values for various constituent elements in coal fry ash are determined in accordance with ASTM Standard Test Method C311-85

General description

A unit of SRM 2690 contains three hermetically sealed glass vials, each containing 10 grams of fly ash that has been pulverized to a particle size of less than 150 μm and blended to achieve a high degree of homogeneity. For more information, please refer to the SDS and COA.
