ASTM E1086 Introduction
ASTM E1086 establishes a standardized procedure for the analysis of austenitic stainless steel using spark atomic emission spectrometry. This method allows for the accurate and rapid determination of the elemental composition of stainless steel alloys, including the concentrations of various alloying elements. It is also used for regular analysis of cold cast discs, as well as for the examination and testing of stainless steel samples with a flat surface and a minimum diameter of 13 mm. By following this test method, manufacturers, suppliers, and end-users can ensure the quality and compliance of austenitic stainless steel materials.
ASTM E1086 Test Method
Representative samples of austenitic stainless steel are collected and prepared for analysis. The test is conducted in the following steps:

Spark Atomic Emission Spectrometry
The prepared samples are placed in the spark spectrometer, which uses high-energy sparks to excite the atoms in the material. The excited atoms emit characteristic wavelengths of light, which are detected and analyzed to determine the presence and concentration of specific elements.A controlled discharge is produced between the counter electrode and the flat surface of the specimen. The radiant energy of selected analytical lines is converted into electrical energy using photomultiplier tubes and are then stored on capacitors. The discharge is ended at a predetermined level of accumulated radiant energy. When the integration period ends, the charge on each capacitor is measured and recorded as relative energy or mass fraction %.
Measurement and Analysis
The emitted spectra are captured by the spectrometer and the intensities of the spectral lines are measured and compared to calibration standards to quantify the elemental concentrations in the austenitic stainless steel.
ASTM E1086 Equipment and Sample Preparation
Specimen details
The specimens used in ASTM E1086 are austenitic stainless steel samples.
Specimen dimensions
The specimen dimensions, shape, and surface conditions are considered based on the testing requirements and the type of analysis equipment used.
Specimen preparation
The samples are in the form of solid pieces, powder, or small chips, depending on the testing equipment and requirements.
ASTM E1086 Results and Interpretation
ASTM E1086 provides quantitative information about the elemental composition of austenitic stainless steel. The test results indicate the concentrations of various alloying elements, such as chromium, nickel, manganese, and others, which are critical for determining the material’s properties and performance. By comparing the obtained composition with specified limits or industry standards, manufacturers and users can ensure the quality and compliance of the austenitic stainless steel.
