N2 - The outstanding work performed by standardization organizations for guidelines to assess hazards, e.g., OECD (Organisation for Economic Co-operation and Development), is clearly visible by the currently available number and broad coverage, from aquatic to terrestrial organisms dealing with environmental relevant issues. Nevertheless, novel materials challenge the adequateness and fit-for-purpose of such standards, as the standards were developed to assess hazards of “conventional” chemical substances and not advanced materials (e.g. materials that may deliberately change behaviour). While standardization is a well-known process that requires extended time before reaching implementation stage, there is strong support from regulatory bodies for the development of New Approach Methodologies (NAMs) (e.g., updating of current guidelines, development of novel omics-, in vitro-, and in silico- tests including modelling and read-across) that meet regulatory preparedness (i.e. have considered issues important for regulatory testing).
