Abstract

The Horizon Europe Project MACRAMÉ •developed twelve recommendations towards Test Guidelines and Standards for safety assessment of advanced materials (AdMas); •identifies needs in characterisation and identification, safety testing, transformation and release as well as information flow along the AdMas life cycle, all captured in the twelve recommendations; •highlights challenges posed by complex structures and transformations of AdMas and AdMas-enabled products for regulation and industry; •draws on research on graphene-related materials, carbon nanotubes and poly(lactic-co-glycolic) acid in realistic use cases; •translates advances in characterisation, transformation and release assessment, and in New Approach Methodologies into actionable recommendations; •calls on regulators, funding bodies, researchers and industry to develop and validate fit-for-purpose test methods, standards and guidance; •aims to enable safe and sustainable deployment of AdMas for societal challenges.
