ISO 12677:2011 PDF

Scope: This International Standard specifies a method for the chemical analysis of refractory andg technical ceramic : raw materials，intermediates and products，by means of the X-ray fluorescence (XRF) fused castrbead : method. Typical materials that can be analysed by this standard are given in Clause 3. This International :Standard is not applicable to _non-oxide materials，such as silicon carbides or nitrides，etc. The method is : applicable to a wide range of materials containing a wide range of elements. : NOTE 1 The presence of significant amounts of certain elements, such as tin, coppem zinc and chromium, can present : difficulties in the fusion process. In this case, the Bibliography can be referred to. NOTE 2 ”Constituents at concentrations greater than 99 % (on a dried basis) are reported by difference,， provided that all likely minor constituents and any loss on ignition have been determined. These figures can also be checked by direct determination.
