Standards & Certification

The reference framework for defining, testing and certifying engineered carbon materials.

What We Offer

Standards Library

A curated, continuously updated reference of the ISO, IEC, ASTM and sector standards that govern carbon materials, filterable by material and application and linked directly to each issuing body.

Quality Classification

Guidance on classifying carbon grades against measurable structural and chemical properties, building on frameworks such as the ISO characterisation standards for graphene and related 2D materials.

Verification and Certification

Support for independent testing, verification and certification pathways, so producers can substantiate performance claims and buyers can specify with confidence.

Task Forces and Working Groups

Member-led groups that develop shared methods and position the industry ahead of formal standardisation, from recycled carbon fibre to biochar carbon removal.

Engineered carbon only becomes a dependable industrial input when buyers can trust what they are buying. A graphene powder, a carbon fibre tow and a biochar batch can each carry the same name and behave completely differently, and that ambiguity is the single biggest brake on adoption across the sector. The Advanced Carbons Council maintains a working library of the international standards that define, measure and certify carbon materials, tracks the committees where those standards are written, and convenes industry task forces to close the gaps that remain. Our aim is straightforward: a shared language and a verifiable basis for quality, so that specification, procurement and regulation can all rest on the same evidence.

Standards library

One headline standard for each advanced carbon material family, drawn from the full ACC standards library.

GrapheneISO/TS 9651:2025Nanotechnologies — Classification framework for graphene-related 2D materialsThe ACC Graphene Classification Framework, published by ISO/TC 229 in July 2025 after several years of work with more than 100 subject matter experts. Specifies the relevant commercial characteristics of graphene-related 2D materials in sheet and particle form, the measurement methods for each, value ranges, a syntax for consistent naming and description, and a technical data sheet template. The reference framework for classifying and comparing graphene materials regardless of production route or feedstock.View all 16 standards→

Assurance

Verification

ACC runs an independent verification programme that assesses carbon material producers against defined technical and quality criteria, including in-person site verification. It underpins the ACC Verified Registry, giving buyers, investors and regulators a trusted, evidence-based view of who can supply what.
