Nanotechnologies are the design, characterisation, production and application of structures, devices and systems by controlling shape and size on a nanometre scale. This includes the manufacture, use, and manipulation of materials at nano-scale. These innovative technologies promise technical and economic advantages in diverse fields, including electronics, and energy production and storage. Despite its promises, the use of nanomaterials comes with risks and potentially harmful impacts on human health and the environment. As voluntary options have repeatedly failed in the past, nanomaterials must be legally required to go through specific risk assessment and evaluation, and risk management measures must be developed before the nanomaterials are placed on the market.

With the definition of nanomaterials in the EU still under revision, and with the REACH Annexes revision still anticipated, the importance of clear, harmonised definitions for nanomaterials and nanotechnologies is crucial. ECOS’ work on this topic aims to provide legal certainty and allow for the development of specific legal requirements at both EU, and international level. 

ECOS will work to support the safe and sustainable development and use of nanomaterials through ambitious sampling, characterisation, and exposure methods for nanomaterials, also in the complex matrix supporting the development of a comprehensive regulatory EU framework.


  • Contribute to international fora working on nanomaterials standards, within CEN, ISO and OECD
  • Contribute to developments related to the characterisation of nanomaterials, scratch testing, waste containing nanomaterials and nanomaterials in construction products
  • Work at OECD level on characterisation, nanotoxicology, risk assessment and management in regulations, especially to follow the testing guidelines on inhalation
  • Promote the development of legal requirements to ensure the safety of nanomaterials for health and the environment, in line with standardisation developments

ECOS contributes to:

  • CEN/TC 352: Nanotechnologies
  • ISO/TC 229: Nanotechnologies
  • OECD Working Party on Manufactured Nanomaterials (WPMN)

Standardisation requests from the European Commission and EFTA

  • M/461: Nanotechnologies and nanomaterials
