Full title and description

ASTM E1019-24 — Standard Test Methods for Determination of Carbon, Sulfur, Nitrogen, and Oxygen in Steel, Iron, Nickel, and Cobalt Alloys by Combustion and Inert Gas Fusion Techniques. This standard defines procedures using combustion and inert-gas fusion methods with appropriate detectors (infrared absorption, thermal conductivity) for quantitative determination of C, S, N and O in a wide range of ferrous and selected non-ferrous alloys.

Abstract

These test methods specify sample handling, combustion and inert-gas fusion operations, and detector techniques to measure carbon, sulfur, nitrogen and oxygen in steel, iron, nickel and cobalt alloys. The standard gives applicable composition limits, recommended test-section organization (C/S by combustion; N by inert-gas fusion with TCD; O by inert-gas fusion with IR or TCD), and guidance on laboratory procedures, instrument manufacturer recommendations, and safety.

General information

• Status: Active standard (E1019-24).
• Publication date: 2024 (designation E1019-24; published/issued in early 2024).
• Publisher: ASTM International.
• ICS / categories: 77.040.30 (Chemical analysis of metals).
• Edition / version: E1019-24 (current active edition).
• Number of pages: 20 pages.

Scope

Applies to determination of carbon (≈0.001–9.50 %), sulfur (≈0.001–0.45 %), nitrogen (≈0.0005–0.50 %) and oxygen (≈0.0005–0.03 %) in steel, iron, nickel and cobalt alloys within the composition ranges listed in the standard. The methods are arranged as: Carbon and Sulfur by combustion (sections 10–19); Nitrogen by inert gas fusion with thermal conductivity detection (sections 20–30); Oxygen by inert gas fusion with infrared absorption or thermal conductivity detection (sections 31–42). The values in SI units are normative, and users must follow appropriate laboratory safety and instrument manufacturer recommendations.

Key topics and requirements

• Combustion analysis procedures for simultaneous measurement of carbon and sulfur (IR detection typically used for CO2 and SO2).
• Inert-gas fusion techniques for nitrogen and oxygen with thermal conductivity detection (TCD) and/or infrared (IR) absorption as specified.
• Specified element concentration ranges and material applicability (steel, iron, nickel and cobalt alloys).
• Calibration, standards, method blanks, and routine quality/precision checks — laboratories are expected to document work procedures and follow manufacturer recommendations.
• Precision and interlaboratory performance data available (research report based on an interlaboratory study).
• Safety, sample preparation (representative sampling, specimen size/shape), and considerations for reactive or specialty alloys.

Typical use and users

Used by accredited analytical laboratories, steel and alloy producers, metallurgical quality control teams, material specification writers, inspection and test laboratories in aerospace, energy, automotive and manufacturing supply chains where precise control of interstitial and trace elements is critical. Laboratories commonly use E1019 to verify conformance to material specifications and customer requirements.

Related standards

Previous and related ASTM documents include earlier editions E1019-18, E1019-11 and older revisions. Complementary or material-specific analysis standards often referenced alongside E1019 include ISO methods for C/S determination (e.g., ISO 15350 for C/S by IR after combustion) and other ASTM methods for reactive materials (examples noted in laboratory guidance). A dedicated research report (RR:E01-2002) documents interlaboratory precision for E1019.
