答案（中文）
原则上，每种纳米形态都必须单独报告。然而，REACH 允许在满足两个条件的情况下报告一组相似的纳米形态：注册人报告该集合中纳米形态表征参数的明确界限；注册人证明可以联合进行纳米形态的危害、暴露和风险评估。该证明必须由该集合中纳米形态的数据支持。有关集合证明的更多信息，请参阅问答 1681。
Answer (EN)
In principle, each nanoform has to be reported separately. However, REACH allows reporting of a set of similar nanoforms when two conditions are fulfilled:   The registrant reports clearly defined boundaries in terms of characterisation parameters of the nanoforms, which are part of the set; The registrant justifies that the hazard, exposure and risk assessment of the nanoforms can be performed jointly. The justification must be supported by data on the nanoforms in the set. For more information on the set justification, refer to Q&A 1681.
