ASTM E415 testing laboratory by OES
Would you like to perform a carbon steel and low-alloy steel testing by OES in accordance with ASTM E415?
Ensuring the safety of metallic materials in the aerospace, space and defense industries with ASTM E415
In the aerospace, space and defensesectors, mastering the chemical composition of steels is a critical safety requirement. The slightest variation in alloying elements or impurities can alter the mechanical performance and corrosion resistance of your corrosion of your critical parts.
The ASTM E415 standard is the reference standard for analyzing carbon and low-alloy steels by spark optical emission spectrometry (OES). It ensures a rapid and extremely accurate assessment of the compliance of steel grades.
At the Filablaboratory, we support industrial companies in the aerospace, space and defense sectors in characterizing and inspecting their materials in accordance with the ASTM E415 standard, with a clear objective: to make your technical and industrial decisions more reliable.
ASTM E415: a key requirement for structural and high-performance steels
Steel testing by OES in accordance with ASTM E415
The ASTM E415 standard defines the OES-standardized test method for the quantitative chemical analysis of 21 elements—including carbon, manganese, phosphorus, sulfur, and silicon—in carbon and low-alloy steels.
It is specifically used to:
- accurately measure alloying elements and residual impurities.
- verify compliance of steel grades with technical specifications (AISI, SAE grades, etc.).
- control quality during material receipt or after forging and foundry operations.
In the aerospace, space, and defense industries, compliance with the levels defined by ASTM E415 has a direct impact on:
- the hardness and tensile properties after heat treatment.
- The weldability and structural integrity of assemblies.
- The service performance of strategic components subjected to fatigue stresses.
The ASTM E415 standard is therefore used for material qualification, quality control, supplier validation, and analysis following a nonconformity.

FAQ
It applies to carbon steels and low-alloy steels. The method is particularly suitable for solid samples whose geometry allows a stable electrical discharge (sparking).
It enables the simultaneous determination of carbon, manganese, silicon, phosphorus, sulfur, chromium, nickel, molybdenum, aluminum, copper, vanadium, and other essential trace elements.
ASTM E415 is based on Optical Emission Spectrometry (OES). An electrical discharge is generated between an electrode and the sample, producing a light spectrum whose intensity at each wavelength makes it possible to quantify the elements present.
- Incoming inspection of bars, sheets, or billets.
- Grade sorting in the event of mixed stock.
- Verification of surface decarburization or carburization.
- Technical support for approval files involving new suppliers.
ASTM E415 is a direct solid-sample technique that is much faster and ideal for routine testing, whereas ICP (E3061) requires dissolution and is often preferred for more complex matrices or very low detection limits for certain specific elements.
