设计标签时，对于标签上使用的危险象形图的尺寸和构成有哪些要求？

When designing a label, what are the requirements regarding dimensions and make-up of the hazard pictograms, to be used on the label?

标签应用的一般规则概述于 CLP 第 31 条。对于危险象形图，如 CLP 第 31 条 (4) 所述，应适用 CLP 附件 I 第 1.2.1 节和 CLP 附件 V 的规定。根据 CLP 附件 V，危险象形图应为白底黑色符号，并带有足够宽的红色边框，以便清晰可见。危险象形图应为设置在一点的正方形。每个危险象形图应至少覆盖专用于 CLP 第 17 条所要求信息的标签最小表面积的十五分之一（定义见 CLP ATP 第二部分附件 I 第 1.2.1.4 节表 1.3）。如果供应商选择使用大于特定容量包装最小尺寸的标签，则象形图的尺寸不必增加，只要其覆盖相关最小尺寸的十五分之一并与包装尺寸保持比例即可。每个危险象形图的最小面积不得小于 1 cm²。请注意，象形图的大小与象形图本身的尺寸有关，而与嵌入象形图的虚拟方块的大小无关。更多指导意见请参阅《根据 CLP 法规进行标签和包装的指南》第 5.2 节“标签和标签要素的尺寸”，该指南可在欧洲化学品管理局 (ECHA) 网站上找到：http://www.echa.europa.eu/guidance-documents/guidance-on-clp。

The general rules for the application of labels are outlined in CLP Article 31. For the hazard pictograms, as detailed in CLP Article 31 (4), the provisions of Annex I, Section 1.2.1, to CLP and Annex V to CLP shall apply. According to Annex V to CLP, hazard pictograms shall have a black symbol on a white background with a red frame wide enough to be clearly visible. Hazard pictograms shall be in the shape of a square set at a point. Each hazard pictogram shall cover at least one fifteenth of the minimum surface area of the label dedicated to the information required by CLP Article 17 (as defined in Table 1.3 in Section 1.2.1.4 of Annex I, 2nd ATP to CLP). Where a supplier chooses to use a label that is larger than the minimum dimensions for a certain capacity of the package, it is not necessary for the size of the pictogram also to be increased, provided it covers one fifteenth of the relevant minimum dimensions and remains proportional to the size of the packaging. The minimum area of each hazard pictogram shall not be less than 1 cm². Note that the size of the pictogram relates to the dimensions of the pictogram itself, and not to the size of the virtual square where the pictogram is embedded. Further guidance can be found in Section 5.2- 'Size of the label and of the label elements' of the Guidance on labelling and packaging in accordance with the CLP Regulation available on ECHA's website at: http://www.echa.europa.eu/guidance-documents/guidance-on-clp.
