答案(中文)
第48条禁止将甲苯作为物质或混合物投放市场,浓度等于或大于0.1%(重量百分比),用于粘合剂和喷漆。胶带由涂在柔性基材上的一层粘合剂组成。由于该限制涉及粘合剂中甲苯的浓度,因此甲苯浓度必须根据胶带上的粘合剂量计算,而不是根据粘合剂和基材的总重量计算。
Answer (EN)
Entry 48 prohibits the placing on the market for supply to the general public of toluene as a substance or in mixtures, in a concentration equal to or greater than 0.1% by weight, where the substance or the mixture is used in adhesives and spray paints. Adhesive tapes consist of a layer of adhesive coated on a flexible substrate. As the restriction concerns the concentration of toluene in adhesives, the concentration of toluene must be calculated with reference to the amount of adhesive on the tape, and not with reference to the total weight of the adhesive and substrate.
