ISO/TS 21623:2017描述了一种系统方法，用于评估纳米材料和/或纳米功能产品的生产和使用所产生的与纳米物体及其团聚体和聚集体（NOAA）相关的潜在职业风险。该方法为确定暴露途径、暴露身体部位以及暴露对皮肤吸收、局部影响和意外摄入的潜在后果提供了指导。 ISO/TS 21623:2017还考虑了专业人士职业性使用含有NOAA的产品，例如使用个人护理产品、化妆品或药品的美容师，但不适用于消费者故意或规定接触这些产品的情况。 ISO/TS 21623:2017旨在帮助职业卫生学家、研究人员和其他安全专业人员识别潜在的皮肤接触及其潜在后果。

ISO/TS 21623:2017 describes a systematic approach to assess potential occupational risks related to nano-objects and their agglomerates and aggregates (NOAA) arising from the production and use of nanomaterials and/or nano-enabled products. This approach provides guidance to identify exposure routes, exposed body parts and potential consequences of exposure with respect to skin uptake, local effects and inadvertent ingestion. ISO/TS 21623:2017 also considers occupational use of products containing NOAA by professionals, e.g. beauticians applying personal care products, cosmetics or pharmaceuticals, but does not apply to deliberate or prescribed exposure to these products by consumers. ISO/TS 21623:2017 is aimed at occupational hygienists, researchers and other safety professionals to assist recognition of potential dermal exposure and its potential consequences.
