如果 IUCLID 第 1.2 节提供了有关纳米形态表征的信息，是否也必须在第 4.28 节中报告此信息？

如果 IUCLID 第 1.2 节提供了有关纳米形态表征的信息，是否也必须在第 4.28 节中报告此信息？

If information on the characterisation of a nanoform is provided in IUCLID section 1.2, is it mandatory to report this information also in section 4.28?

要注册某种物质的纳米形式，必须按照 REACH 附件 VI 的定义，在 IUCLID 的 1.2 和 1.4 节中报告其特性参数。这些章节中报告的信息是指在注册范围内对物质的组成/形式的识别。每个注册人分别提交这些信息。然后，在 IUCLID 的第 4-7 节中报告纳米形式的附件 VII-X 信息要求。这些信息可以由牵头注册人代表共同注册人联合提交；也可以由共同注册人通过选择退出机制单独提交。虽然 IUCLID 第 4.28 节包含用于报告纳米材料某些物理化学性质的（稳健）研究摘要的模板，但 4.28 中唯一与强制性附件 VII-X 信息要求相对应的子节是第 4.28.8 节 - 纳米材料尘埃。 4.28 下的其余小节不需要作为注册档案的一部分提供。

To register a nanoform of a substance, you must report its characterisation parameters in sections 1.2 and 1.4 of IUCLID, as defined by REACH Annex VI. The information reported in these sections refers to the identification of the compositions/forms of the substance within the scope of the registration. It is submitted separately by each registrant.  The Annex VII-X information requirements for the nanoform are then reported in sections 4-7 of IUCLID. This information can be submitted jointly by the lead registrant on behalf of the co-registrants; or separately by co-registrants via the opt-out mechanism. While IUCLID section 4.28 contains the templates for reporting (robust) study summaries of certain physicochemical properties for nanomaterials, the only sub-section in 4.28 that corresponds to a mandatory Annex VII-X information requirement is section 4.28.8 – Nanomaterial dustiness. The remaining sub-sections under 4.28 do not need to be provided as part of a registration dossier.
