NanoHarmony announced on November 10, 2023, the release of the NanoHarmony OECD TG/GD Process Mentor, an interactive web-based tool to guide stakeholders through the development process of Organization for Economic Cooperation and Development (OECD) Test Guidelines (TG) and Guidance Documents (GD). NanoHarmony states that it developed the NanoHarmony OECD TG/GD Process Mentor to highlight the involvement of key institutions in the OECD Test Guidelines Programme, and their incentives to take part...

NanoHarmony published on October 13, 2023, a white paper entitled From Science to Regulation: The NanoHarmony White Paper on Test Guideline Development. NanoHarmony states that the Organization for Economic Cooperation and Development’s (OECD) Test Guidelines (TG) Programme helps to develop harmonized agreed methods that can be used by OECD member countries to implement their regulatory regimes. According to NanoHarmony, for regulations to be effective and for manufacturers to be able to...

The Organization for Economic Cooperation and Development (OECD) announced on July 4, 2023, that it published a number of new, updated, and corrected Test Guidelines (TG), including the following for nanomaterials: On July 4, 2023, OECD also released a corrected version of its Report on the WNT Workshop how to prepare the Test Guidelines Programme for emerging technologies. The Working Party of the National Coordinators of the TG Program (WNT) held a workshop in December 2022 on...

The Organization for Economic Cooperation and Development (OECD) will hold a webinar on February 7, 2023, on Test Guideline (TG) No. 125: Nanomaterial Particle Size and Size Distribution of Nanomaterials. OECD states that it will present the methods described in TG No. 125 to determine the size and size distributions of nanomaterial particles and fibers spanning from one nanometer (nm) to 1,000 nm. During the webinar, attendees will be able to learn the use and limitation of the...

NanoHarmony and NANOMET have published a status report summarizing the current status of projects aiming to develop or adapt Organization for Economic Cooperation and Development (OECD) Test Guidelines (TG) and Guidance Documents (GD) for nanomaterials, as well as the outlook for each project as of July 2022. The status report is intended to be a living document that will be updated regularly. A large part of the status report comprises activities in European Union (EU) projects like...

On June 30, 2022, the Organization for Economic Cooperation and Development (OECD) published six new Test Guidelines (TG) and ten updated or corrected TGs. The new TGs include the first two harmonized methods for measuring certain nanomaterial-specific physical-chemical properties. According to OECD, these harmonized methods were developed to respond to regulatory needs in member and adhering countries, specifically for manufactured nanomaterials. The development of these TGs was...

The NanoHarmony and NANOMET projects are holding their first face-to-face joint workshop on the development of Organization for Economic Cooperation and Development (OECD) test guidelines (TG) for nanomaterials back-to-back with the OECD Working Party on Manufactured Nanomaterials (WPMN) at the OECD Conference Center in Paris on June 29-30, 2022. NanoHarmony aims to facilitate and improve the development process of TGs from the perspective of the developers, users, and...

NanoHarmony aims to support the development of Organization for Economic Cooperation and Development (OECD) test guidelines (TG) and guidance documents (GD) for eight endpoints where nanomaterial-adapted test methods have been identified as a regulatory priority. NanoHarmony states that it is looking to create guidance for the development of other TGs and GDs in the future that will create a more efficient pathway to develop these. To help learn best practice in this area, the NanoHarmony...
