Which international or industry standards do your carbon and sulfur analyses comply with?

Our carbon and sulfur analytical procedures and equipment are rigorously calibrated to comply with a suite of internationally recognized standards, ensuring the data integrity and material traceability required for high-stakes industries. This compliance is a foundational element of our quality management system.

Primary International Standards for Combustion Analysis

The core methodology for carbon and sulfur determination in metals is governed by several key standards, which we adhere to strictly:

• ASTM E1019: Standard Test Methods for Determination of Carbon, Sulfur, Nitrogen, and Oxygen in Steel and in Iron, Nickel, and Cobalt Alloys. This is a foundational method for combustion and inert gas fusion techniques, providing detailed procedures for a wide range of ferrous and non-ferrous materials, including the Superalloys and Stainless Steels we commonly process.

• ISO 15350: Iron and steel — Determination of carbon and sulfur content — Infrared absorption method after combustion in an induction furnace. This international standard is widely referenced in global supply chains, particularly for automotive and general manufacturing.

• AMS 2628: Determination of Carbon and Sulfur in Superalloys. This Aerospace Material Specification provides a tailored protocol for analyzing high-performance nickel and cobalt-based superalloys used in Aerospace and Aviation applications, demanding extreme precision at low ppm levels.

Industry-Specific and Material-Specific Specifications

Beyond the analytical methods themselves, our compliance extends to the material specifications that define acceptable chemical limits. Our analysis reports directly verify conformity to:

• Aerospace Specifications: Such as various DMS (Defense Material Specifications) and AMS (Aerospace Material Specifications) for titanium, aluminum, and superalloy powders.

• ASTM Material Standards: For additive manufacturing, this includes standards like:

  • ASTM F2924 for Titanium Alloy Ti-6Al-4V

  • ASTM F3055 for Nickel Alloy (Inconel 718)

  • ASTM F3184 for Stainless Steel 17-4PH

• Medical Standards: For implants, we ensure materials comply with standards such as ASTM F2066 for Nitinol or ISO 5832-2 for Wrought Titanium, where controlled interstitial content is critical for biocompatibility and performance.

Implementation and Quality Assurance

Our adherence to these standards is not merely a matter of procedure. It is embedded in our daily operations through:

• Calibration and Validation: Regular calibration of our analyzers using NIST-traceable (National Institute of Standards and Technology) reference materials of known carbon and sulfur content.

• Proficiency Testing: Participation in inter-laboratory comparison programs to benchmark our results against other accredited labs, ensuring ongoing accuracy.

• Strict Internal Protocols: Our internal quality procedures often exceed the minimum requirements of these standards, especially for the ultra-low impurity levels demanded by Powder Bed Fusion processes for critical components.

In essence, our carbon and sulfur analysis provides the verified data necessary to certify that your materials—from incoming powder to finished part—conform to the exacting standards of your industry, whether it be Medical and Healthcare, Aerospace and Aviation, or Energy and Power.
