ISO/TR 19057:2017回顾了在评估纳米材料及其配体在模拟生物和环境介质中的生物耐久性时实施的无细胞体外测试和方法的使用和应用。 ISO/TR 19057:2017旨在更多地关注为评估生物耐久性而实施的非细胞体外方法学，因此排除了对体外细胞或动物生物耐久性试验相关文献的一般性审查。

ISO/TR 19057:2017 reviews the use and application of acellular in vitro tests and methodologies implemented in the assessment of the biodurability of nanomaterials and their ligands in simulated biological and environmental media. ISO/TR 19057:2017 is intended to focus more on acellular in vitro methodologies implemented to assess biodurability and, therefore, excludes the general review of relevant literature on in vitro cellular or animal biodurability tests.
