The Advanced Carbons Council (ACC) has announced the official publication of the Graphene Classification Framework as an ISO technical specification, marking a major step toward standardizing graphene-related materials for commercial use.
Published as ISO/TS 9651:2025, "Nanotechnologies - Classification framework for graphene related 2D materials", the document defines the key characteristics of graphene-related 2D materials in both sheet and particle forms, alongside applicable measurement methods for industrial applications. The framework also introduces a consistent naming syntax and a technical data sheet template to improve transparency in the marketplace.
Developed over several years with contributions from more than 100 subject matter experts, the classification framework addresses a critical gap in the standardization of nanomaterials such as graphene, carbon nanotubes (CNT), and related carbon-based fillers. These materials are increasingly used in composites to enhance performance, reduce weight, and improve sustainability.
The initiative began with the Graphene Council (now ACC), which recognized the need for a globally accepted classification system to support quality assurance, buyer confidence, and wider commercialization. By aligning producers, end users, and testing standards, ISO/TS 9651:2025 is expected to accelerate adoption of graphene materials in advanced manufacturing sectors.
