Overview
CEN ISO/TS 80004-8:2020 (also published as ISO/TS 80004-8:2020) is a technical specification that provides a standardized vocabulary for nanomanufacturing processes. It defines terms used across directed assembly, self‑assembly, synthesis and fabrication at the nanoscale. The document clarifies language used by researchers, engineers, regulators and industry so that discussions about nanotechnologies and nanomanufacturing processes are consistent and interoperable across sectors.
Key topics
The specification organizes terminology by process type and scope rather than prescribing process parameters. Major topics covered include:
- General terms and contextual definitions reproduced from other ISO/TS 80004 parts (Clause 3) for clarity.
- Directed assembly and self‑assembly process vocabulary (Clauses 5–6).
- Synthesis processes categorized by phase and method:
- Gas‑phase, liquid‑phase and solid‑phase processes
- Physical and chemical synthesis methods (including flame synthesis and related terms) (Clause 7)
- Fabrication processes for nanoscale structures:
- Nanopatterning and lithography terminology (Clause 8.1)
- Deposition, etching, printing and coating terms (Clauses 8.2–8.4)
- Annex A mapping: identification of output from synthesis processes (which processes yield nano‑objects, nanoparticles, or may produce larger‑scale features)
- Notes on terms that are not exclusive to the nanoscale and the conditions under which processes produce nanoscale features.
The document does not attempt to define tools, metrology techniques or detailed process parameters; it focuses on consistent naming and contextual usage.
Applications
CEN ISO/TS 80004-8:2020 is practical for:
- Harmonizing terminology in R&D, process development and scale‑up for nanomaterials
- Supporting procurement, specifications and contract language in manufacturing and supply chains
- Improving clarity in regulatory submissions, safety data sheets and workplace health & safety documentation
- Enabling clear communication between multidisciplinary teams in semiconductor, electronics, aerospace, energy, pharmaceuticals, packaging, textiles and other industries using nanomaterials
Who should use this standard
- Nanotechnology researchers and process engineers
- Quality, compliance and regulatory teams
- Technical writers, standards committees and policy makers
- Procurement and supply‑chain managers involved with nanomaterials and nanoenabled products
