PD CEN ISO TS 80004 — Nanotechnologies Vocabulary
Nanotechnologies — Vocabulary (CEN ISO/TS 80004)
🔬 The PD CEN ISO/TS 80004 series is a set of nanotechnologies Vocabulary Technical Specifications issued in the UK as “Published Documents”, identical to CEN ISO/TS 80004 (corresponding to ISO/TS 80004). Developed jointly by ISO/TC 229 (Nanotechnologies) and CEN/TC 352 (Nanotechnologies), the series provides unified terminology definitions for nanotechnologies, covering core concepts, nanostructured materials, nano-object characterisation, and nanomanufacturing processes. BSI Technical Committee NTI/1 (Nanotechnologies) is responsible for UK participation, classified under ICS 01.040.07 / 07.030. This article presents the series as a whole: its structure and terminology system.
💡 Nanotechnologies span physics, chemistry, biology, and materials science; concepts such as “nanomaterial”, “nano-object”, and “nanostructure” carry very different meanings in different contexts. ISO/TS 80004 pins down these concepts with rigorous definitions, avoiding confusion in regulation, testing, and commercial claims.
1. Series Overview 📌
The ISO/TS 80004 vocabulary series is published by topic. The four parts in this batch are as follows:
| Part | Edition | Subject | Main Content |
|---|---|---|---|
| PD CEN ISO/TS 80004-1 | 2015 | Part 1: Core terms | Defines foundational core terms of nanotechnologies; the common basis for the rest of the series. |
| PD CEN ISO/TS 80004-4 | 2014 | Part 4: Nanostructured materials | Defines terminology for nanostructured materials (nanoparticles, nanofibres, nanoplates, etc.). |
| PD CEN ISO/TS 80004-6 | 2015 | Part 6: Nano-object characterisation | Defines terminology for nano-object characterisation (measurement parameters, characterisation methods, etc.). |
| PD CEN ISO/TS 80004-8 | 2015 | Part 8: Nanomanufacturing processes | Defines terminology for nanomanufacturing processes and methods (scan version; written from public domain knowledge). |
⚠️ Part 8 (80004-8:2015) is a scan-only file in the source material; its content is summarised from public domain knowledge. Always refer to the official BSI published version.
2. Core Terms and Nanoscale Definitions 📏
Part 1 (Core terms) is the foundation of the whole vocabulary, establishing the framework for core definitions such as “nanotechnology”, “nanoscale”, “nano-object”, “nanomaterial”, and “nanostructure”. The nanoscale generally refers to the size range of approximately 1 nm to 100 nm; nanotechnologies involve the controlled manipulation, measurement, or use of matter at that scale, where properties may differ significantly from macroscopic or atomic scales. Unified core terms are the prerequisite for defining specific concepts in Parts 4, 6, and 8.
Part 4 (Nanostructured materials) further defines material-level terms: nanoparticles (three dimensions at nanoscale), nanofibres (two dimensions at nanoscale), nanoplates/nanoflakes, and nanostructured materials composed of nanoscale building blocks (e.g., nanocomposites, nanocrystalline materials, aerogels).
| Terminology Topic | Typical Terms | Definition Points |
|---|---|---|
| Core concepts | Nanotechnology, nanoscale, nano-object | Design, characterisation, and use at ~1–100 nm |
| Nano-objects | Nanoparticle, nanofibre, nanoplate | Classified by number of dimensions at nanoscale |
| Nanostructured materials | Nanocomposite, nanocrystalline, aerogel | Material systems containing nanoscale structural units |
| Characterisation (measurement) | Size distribution, specific surface area, morphology parameters | Describing nano-object properties and measurement methods |
| Manufacturing processes | Top-down, bottom-up, self-assembly | Routes for preparing nanostructures and materials |
3. Characterisation and Manufacturing Terminology ⚙️
Part 6 (Nano-object characterisation) defines characterisation terms: nano-object size and size distribution, specific surface area, morphology, surface chemistry, and terms related to measuring these parameters. Unified characterisation terminology is essential for nanomaterial quality qualification, regulatory declarations (e.g., nanoforms under EU REACH), and safety assessment.
Part 8 (Nanomanufacturing processes) defines process and method terminology for nanomanufacturing, such as top-down (machining nanostructures from bulk material, e.g., lithography, micro/nanofabrication) and bottom-up (assembling nanostructures from atoms/molecules, e.g., chemical vapour deposition, self-assembly, sol-gel) preparation routes.
🚨 Nanomaterial safety and compliance depend heavily on “clear definitions and consistent measurement”: the same substance may fall into different regulatory categories under different size definitions. Always use ISO/TS 80004 terminology to define material form and apply compliant measurement methods.
4. Engineering Practice 🛠️
- 📋 R&D communication: use unified terminology among R&D teams, suppliers, and customers to avoid specification disputes from differing “nanomaterial” meanings.
- 🧪 Testing and characterisation: define characterisation parameters (size distribution, specific surface area, etc.) per Part 6 and choose corresponding measurement methods for comparable data.
- 📊 Regulatory compliance: use standard terminology to define nanoforms in chemical registration, health and safety assessment, and product declarations, supporting compliance documentation.
- 🛠️ Process description: describe nanomanufacturing process chains using Part 8 terminology for standardised process documentation and traceability.
5. Frequently Asked Questions ❓
❓ Q: Why do nanomaterials need a dedicated terminology standard?
A: At the nanoscale, material properties become scale-dependent, and “nanomaterials” encompass diverse forms (particles, fibres, plates, films, porous materials). Inconsistent terminology causes serious confusion in testing, regulation, and commerce; a unified vocabulary is the infrastructure for R&D and oversight.

❓ Q: What is the difference between “nano-object” and “nanostructured material”?
A: A nano-object is a discrete object with dimensions at the nanoscale (particle, fibre, plate, etc.); a nanostructured material is a material system with nanoscale internal structure (e.g., nanocrystalline metal, nanocomposite). The definitions complement each other.

❓ Q: Who is Part 6 “characterisation” terminology most important to?
A: Most important to nanomaterial producers, testing laboratories, and regulators — unified characterisation parameters (size distribution, specific surface area, morphology, surface chemistry) are prerequisites for test comparability and compliance declarations.
