该欧洲标准是用于测定用于与食品接触的纸张或纸板的水提取物中的重金属的一系列标准品。本欧洲标准规定了水提取物中镉和铅的测定方法。 适用于可提取金属含量超标的纸和纸板 - 0.1mg/kg镉; - 铅含量为0.6mg/kg。 注1:上述确定限度是通过将现在或欧洲现有的实际限额乘以0.2来实现的。 注2:如果非常敏感的设备可用，并且所有其他实验室条件满足微量元素分析的要求，则可以通过本欧洲标准测量低于该值的金属含量

This European Standard is one in a series of Standards for the determination of heavy metals in an aqueous extract of paper or board intended for contact with food. This European Standard specifies the test method for the determination of cadmium and lead in an aqueous extract. It is applicable to paper and paperboard with extractable metal contents exceeding - 0,1 mg per kg for cadmium; - 0,6 mg per kg for lead. NOTE 1 The above limits of determination are achieved by multiplying the actual limits existing today or proposed in Europe by 0,2. NOTE 2 Metal content levels below those given can be measured by this European Standard if very sensitive equipment is available and if all other laboratory conditions fulfil the requirements for trace element analysis.
