TY - CONF A1 - Bresch, Harald T1 - OECD TG 125 Particle size and size distribution of Nanomaterials N2 - This presentation was held in an OECD Webinar introducing the newly developed and published OECD TG 125 on particle size and size distribution. The presentation is explaining the structure if the TG 125 and addresses all included methods and methodologies in a short and understandable way for the broader public. The presentation includes sections about nano-particles and nano-fibres.

This TG is still a valid document for the measurement of particles all over the world. When nanomaterials gained importance, ISO set up a technical commitee for Nanotechnologies in 2005 and the OECD followed this step in 2006 with the Working Party on Manufactured Nanomaterials. In the following years ISO and OECD published several documents about nanomaterials and the systematisation developed. In 2017 it was finally clear that nanomaterials need to be adressed in another way than chemicals and in 2020 ECHA revised the REACH-Annexes accordingly and included nanomaterials. Unfortunately there is a little problem with this: Only a few applicable test guidelines exit for the measurement of the nanomaterials. Several test guidelines date from 1981 and do not address nanomaterials. The logical next step for the OECD would be to publish a series of test guidelines which are indeed currently prepared and will be shown in this talk. Finally there is an additional need for the future of NM standardisation: Digitalisation.

SOPs are available for the disciplines of physical-chemical characterisation, for toxicology, for environmental applications and for exposure applications. Furthermore the SOPs need to be integrated in the regulatory framework and need to be detailed enough for the digital processing. This is highlighted in this presentation.

This presentation is a gap analysis and stakeholder mapping for particles in air, from engineered to natural materials. The analysis was requested for the following points: (1) critical literature on stakeholder needs and relevant metrology (2) existing reference materials and relevant interlaboratory comparisons (3) relevant metrology projects (4) critical stakeholders and stakeholder networks and stakeholder surveys T2 - CCQM IAWG/SAWG TG Particle Metrology CY - Online meeting DA - 09.07.2024 KW - CCQM KW - Particle KW - Nano KW - Characterization KW - Aerosol PY - 2024 AN - OPUS4-62067 LA - eng AD - Bundesanstalt fuer Materialforschung und -pruefung (BAM), Berlin, Germany ER - TY - CONF A1 - Bresch, Harald T1 - Nanoparticle Characterisation - The long way to standardisation N2 - Diese Präsentation gibt einen Überblick über die Entwicklung der Nanopartikelforschung von ca. 2005 bis heute.

It further describes research activities at BAM concerning the characterization of nanoparticles and the way to the digital representation of these characterization possibilities. It concludes with the challenges of a digital product passport (DPP) for nanomaterial based products and the need of a digital materials passport (DMP). Finally, the activities of BAM are presented which address the former mentioned challenges from ESRP and DPP.
