如果我在 IUCLID 6.4 发布之前已经提交了注册档案，表明我将物质作为纳米形式涵盖，那么考虑到纳米形式的新信息要求，我是否仍需要提交更新？

如果我在 IUCLID 6.4 发布之前已经提交了注册档案，表明我将物质作为纳米形式涵盖，那么考虑到纳米形式的新信息要求，我是否仍需要提交更新？

If I already submitted my registration dossier indicating that I cover the substance as a nanoform before the release of IUCLID 6.4, do I still need to submit an update in view of the new information requirements for nanoforms?

是的，您需要提交注册更新。只有 2019 年 10 月发布的 IUCLID 6.4 版及后续版本才包含报告修订版 REACH 附件中纳米形态所需信息的格式，例如附件 VI 中规定的表征参数以及附件 VII 中关于粉尘度的要求。

Yes, you need to submit an update of your registration. Only IUCLID version 6.4, published in October 2019, and later versions of IUCLID contain the formats to report the information required by the revised REACH Annexes for nanoforms, such as the characterisers specified by Annex VI and the Annex VII requirement on Dustiness.
