Vocabulary
- ISO/TS 80004-13:2017 — Nanotechnologies — Vocabulary — Part 13: Graphene and related two-dimensional materials. First edition.
- ISO/TS 80004-13:2024 — Second edition (Sep 2024). Cancels 2017. Adds graphene-related 2D material (GR2M) among other revisions. Joint ISO/IEC circulation in the draft trail.
- Related core vocab still cited by those parts: ISO/TS 80004-1 (core terms), 80004-2 (nano-objects), 80004-6 (nano-object characterization).
Structural characterization of powders and dispersions
- ISO/TS 21356-1:2021 (first edition, March 2021). Sequence of methods after isolating flakes: layer number / thickness, lateral size, disorder, layer alignment, specific surface area. Covers graphene, bilayer, nanoplatelets from powder or liquid. Raman, SEM, AFM, TEM, BET in the usual toolkit. CEN adopted as CEN ISO/TS 21356-1:2022.
How this site maps the words
| Site word | We mean | Do not hear |
|---|---|---|
| Graphene | Honeycomb sheet; say monolayer if we mean one layer | Any black powder |
| FLG | A few layers, when the paper counts them | GO paper |
| GNP / nanoplatelet | Thicker stack sold as graphene | 2004 Manchester flake |
| GO | Oxidized sheets from graphite oxide | Vaccine antigen |
| rGO | GO with oxygen pulled back | Defect-free CVD |
| CVD film | Grown then often transferred | 4,000 t powder |
| GR2M | ISO 2024 umbrella for graphene-related 2D materials | A new allotrope |
What a standard is not
Not a bag certificate. Not a health clearance. Not proof a vendor is “ISO graphene certified” because the letters appear on a slide.
