如何计算我的物品中候选清单物质的总量？

How do I calculate the total amount of the Candidate List substance in my articles?

触发您通知义务的条件之一是，当所有生产和/或进口的物品中候选清单物质的总量超过每个参与者每年一吨时。相关物品应含有超过 0.1% w/w 的物质。如果物品中物质的浓度低于 0.1% w/w，则该物品不必包含在吨位计算中。计算同一参与者生产或进口的所有物品（无论是分离的还是包含在复杂物体中）中同一种候选清单物质的总量（以吨为单位）需要 3 个步骤：1. 确定所讨论的候选清单物质在每个生产或进口的物品中的含量是否超过 0.1% w/w 的浓度阈值。物品或复杂物体中候选清单物质的浓度计算按照物品中物质要求指南表 5 中所述进行。 2. 计算每年生产或进口的每种物品或物品类型中候选清单物质的吨数，其中该物质的含量超过0.1% w/w的浓度阈值。3. 将根据上述第2点计算出的每种物品或物品类型的总量相加，计算所有物品的总量（以吨为单位）。每年1吨的限值适用于同一法人实体在欧洲经济区（EEA）生产/进口的总吨数。如果您认为您的含量接近某个阈值，但不确定是否超过该阈值，我们建议您进行申报。《物品中物质要求指南》第3.2.3.2章提供了进一步的解释，即关于物品类型的概念以及如何计算吨数的示例。《物品中物质要求指南》可在欧洲化学品管理局（ECHA）网站上获取：http://echa.europa.eu/guidance-documents/guidance-on-reach

One of the conditions that triggers the obligation for you to notify is when the total amount of the Candidate List substance present in all articles produced and/or imported exceeds one tonne per actor per year. The articles concerned should contain more than 0.1% w/w of the substance. If an article contains the substance at a concentration below 0.1% w/w, this article does not have to be included in the tonnage calculation. The calculation of the total amount in tonnes of the same Candidate List substance in all articles produced or imported (either isolated or incorporated in complex objects) by the same actor requires 3 steps: 1. Determination on whether the Candidate List substance in question is present at above the 0.1% w/w concentration threshold for each article produced or imported. The calculation of the concentration of the Candidate List substances in articles or complex objects is done as described in Table 5 of the Guidance on requirements for substances in articles. 2. Calculate the amount in tonnes of the Candidate List substance in each article or article type produced or imported per year where it is present above the 0.1% w/w concentration threshold. 3. Calculate the total amount in tonnes for all articles by summing up the amounts calculated for each article or article type according to point 2 above. The one tonne per year limit applies to the total tonnage produced/imported, in the European Economic Area (EEA) by the same legal entity. If you believe you are close to one of the thresholds but are unsure whether you exceed it or not, we recommend you to notify. Chapter 3.2.3.2 of the Guidance on requirements for substances in articles provides further explanations, namely on the concept of article type, and examples on how to calculate the tonnage.
