(Test Method)Standard Test Method for Analysis of Ni-Base Alloys by X-ray Fluorescence Spectrometry
Standard Test Method for Analysis of Ni-Base Alloys by X-ray Fluorescence Spectrometry
SCOPE
1.1 This test method covers the analysis of Ni-base alloys by wavelength dispersive X-ray Fluorescence Spectrometry for the determination of the following elements:Note 1
Unless exceptions are noted, concentration ranges can be extended by the use of suitable reference materials. Once these element ranges are extended they must be verified by some experimental means. This could include but not limited to Gage Repeatability and Reproducibility studies and/or Inter-laboratory Round Robin studies. Once these studies are completed, they will satisfy the ISO 17025 requirements for capability.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
