【国外标准】 Standard Test Method for Analysis of Low-Alloy Steels and Cast Irons by Wavelength Dispersive X-Ray Fluorescence Spectrometry (Withdrawn 2021)

This test method is comparative and intended for use as a routine method to test materials for compliance with compositional specifications. It is assumed that all who use this test method will be trained analysts capable of performing common laboratory procedures skillfully and safely. It is expected that work will be performed in a properly equipped laboratory under appropriate quality control practices, such as those described in Guide E882.1.1 This test method covers the X-ray fluorescence spectrometric analysis of low-alloy steels and cast irons for the following elements in the ranges indicated: Elements Mass Fraction Range, % Manganese 0.20 to 1.50 Nickel 0.10 to 1.00 Chromium 0.10 to 1.00 Molybdenum 0.04 to 0.40 Copper 0.05 to 0.30 Vanadium 0.03 to 0.25Note 1—These mass fraction ranges can be extended by the use of suitable reference materials. The detection limit for the elements is lower than the listed minimum value. The ranges represent the actual levels at which this test method was tested.1.2 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 determine the applicability of regulatory limitations prior to use.
