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

BS EN 12697-31:2019 supersedes BS EN 12697-31:2007

It provides a framework for the manufacture of high-quality single-use flexitanks

Chemical analysis of aluminosilicate refractory products (alternative to the X-ray fluorescence method) - Inductively coupled plasma and atomic absorption spectrometry methods shop-only whose amplitude decays exponentially with1 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)
