The International Organization for Standardization (ISO) recently published two new standards for graphene-related 2D materials, a step forward in supporting the growth of the global graphene industry.
This development is part of an ongoing international effort to bring consistency and comparability to the graphene ecosystem. Over the past several years, multiple organizations, consortia, and research bodies have worked to define reliable frameworks for classification, measurement, and reporting. These new documents from ISO represent another piece of that puzzle, helping ensure that graphene materials can be evaluated and traded on a global scale with transparency and confidence.
The new standards are:
- ISO/TS 9651:2025 provides a classification framework for graphene-related 2D materials in sheet and particle form. This includes standardized characteristics, measurement methods, ranges of values, consistent naming conventions, and a technical data sheet template—bringing much-needed clarity to both producers and end-users.
- ISO/TS 23359:2025 establishes methods for the chemical characterization of graphene materials in powders and liquid dispersions. By outlining reliable approaches with techniques like XPS, TGA, ICP-MS, and FTIR, it ensures manufacturers and researchers can evaluate purity, composition, and performance reproducibly across the industry.
Standards like these do more than set technical baselines—they build trust, interoperability, and transparency. With reliable classification and characterization, companies can evaluate suppliers more effectively, streamline R&D, ensure quality control, and accelerate commercialization of graphene-based solutions across industries such as electronics, composites, energy storage, and healthcare.
