ISO 15819:2014描述了化妆品和化妆品原料中N-亚硝基二乙醇胺（NDELA）的检测和定量方法。 本方法不适用于除NDELA以外的亚硝胺的检测和/或定量，也不适用于除化妆品或化妆品原料以外的产品中NDELA的检测和/或定量。 如果产品可能因成分而受到NDELA污染，或因成分组成而形成NDELA，则该方法适用于NDELA的定量测定。因此，该方法不适用于化妆品的常规检测。由于该应用领域的化妆品种类繁多，该方法可能需要适用于某些基质（参考ISO 12787）。

ISO 15819:2014 describes a method for the detection and quantification of N-nitrosodiethanolamine (NDELA) in cosmetics and raw materials used in cosmetics. This method is not applicable to the detection and/or quantification of nitrosamines other than NDELA nor to the detection and/or quantification of NDELA in products other than cosmetics or raw materials used in cosmetics. If a product has a possibility of either NDELA contamination from ingredients or NDELA formation by the composition of ingredients, the method is intended to be applied for quantitative determination of NDELA. Accordingly, the method does not apply to routine testing of cosmetic products. Because of the large variety of cosmetic products within this field of application, this method might need to be adapted for certain matrices (refer to ISO 12787).
