Stationary source emissions — Chemical absorption method for sampling and determining mercury specie...
This method applies to the sampling and determination of elemental mercury, oxidized mercury, particulate mercury, and total mercury from coal-fired stationary sources. Although there are several methods for the measurement of mercury in flue gas, none of them are applicable for the measurement of mercury in sources with high particulate loadings.
The proposed method builds on the proven…

Metallic powders — Test method for the determination of non-metallic inclusions in metal powders usi...
ISO 13947:2011 specifies a metallographic method for determining the non-metallic inclusion level in metal powders using a powder-forged specimen. The test method covers repress powder-forged test specimens in which there has been minimal lateral flow (< 1 %). The core region of the powder-forged test specimen contains no porosity detectable at 100 ´ magnification.
This test method can also be…
