They are manufactured from cold-reduced grain-oriented silicon-iron alloy strip

The first (Method A) is based on strain rates (including crosshead separation rate)

Chemical analysis of aluminosilicate refractory products (alternative to the X-ray fluorescence method) - Inductively coupled plasma and atomic absorption spectrometry methods shop-only — automatic shut-off valves1 Scope This part of ISO 21587 specifies inductively coupled plasma atomic emission (ICP AE) spectrometry and flame atomic absorption (FAA) spectrometry methods for the chemical analysis of aluminosilicate refractory products and raw materials. The methods are applicable to the determination of the following: silicon(IV) oxide (SiO2) aluminium oxide (Al2O3) iron(III) oxide (total iron oxide calculated as Fe2O3) titanium(IV) oxide (TiO2) manganese(II)
