Description

SRM 2690 - Coal Fly Ash

These Standard Reference Materials (SRMs) are intended for use in the evaluation of analytical methods and techniques used for the classification of coal fly ash and for the determination of constituent elements in coal fly ash or materials with a similar matrix. Each SRM consists of 3 hermetically sealed glass vials of fly ash pulverized to less than 145 µm particle size and blended to a high degree of homogeneity.
