Towards test guidelines and standards for advanced materials: scientific insights and recommendations from the MACRAMÉ project.

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