Would you like to have a stainless steel testing performed by OES in accordance with ASTM E1086?
Securing metal materials in the ASD industry through OES testing in accordance with ASTM E1086
In the aéronautique, space and defense sectors, compliance of corrosion-resistant alloys corrosion is a safety imperative. The slightest variation in the levels of chromium, nickel or molybdenum can compromise the mechanical performance and environmental resistance of your critical parts.
The ASTM E1086 standard is specifically used for the testing of austenitic stainless steels by spark optical emission spectrometry (OES). It enables high-fidelity verification of your steel grades (type 304, 316, 321, etc.) to guarantee their integrity.
At the FILABlaboratory, we support industrial companies in the aerospace, space and defense sectors in the characterization and testing of their materials according to ASTM E1086, with one clear objective: to make your technical and industrial decisions more reliable.
The ASTM E1086 standard: a key issue for stainless steels
Stainless steel testing by OES in accordance with ASTM E1086
The ASTM E1086 standard defines a standardized test method for the quantitative chemical testing of austenitic stainless steels using the spark technique. It covers the determination of major elements and residual impurities essential to the stability of the austenitic structure.
It is specifically used to:
- accurately measure chromium and nickel contents, which ensure resistance to oxidation.
- verify compliance of steel grades with international standards.
- control purity and the absence of undesirable elements that could weaken the alloy.
In the aerospace, space and defense industries, compliance with the thresholds established by ASTM E1086 has a direct impact on:
- intergranular and pitting corrosion resistance.
- mechanical performance in aggressive environments or at extreme temperatures.
- the long-term reliability of strategic components such as fasteners, tubing or structural elements.
The ASTM E1086 standard is therefore used for material qualification, quality control, supplier validation and analysis following a nonconformity.

FAQ
It is specifically designed for austenitic stainless steels (such as 304/304L, 316/316L). It applies to solid samples whose surface can be prepared for spark testing.
This standard makes it possible to quantify Chromium, Nickel, Molybdenum, Manganese, Silicon, Copper, as well as Carbon, Phosphorus and Sulfur simultaneously.
ASTM E1086 is based on Optical Emission Spectrometry (OES). An electrical discharge (spark) vaporizes a small amount of material, generating a light spectrum that makes it possible to identify and quantify each chemical element.
- Validation of material certificates upon receipt.
- Verification of carbon content for "L" grades (Low Carbon).
- Grade identification after machining or welding.
- Investigation following unexpected corrosion onset on a part in service.
