Soveltamisala

Suomenkielistä soveltamisalaa ei ole saatavissa.

ISO 12677:2011 specifies a method for the chemical analysis of refractory and technical ceramic raw materials, intermediates and products, by means of the X-ray fluorescence (XRF) fused cast-bead method. Typical materials that can be analysed by ISO 12677:2011 are given in Clause 3. ISO 12677:2011 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.
