标准摘要
[中文适用范围]: 该程序适用于灌装过程中的原油或精炼产品,或已装在桶中或可移动或固定罐中的产品。 由于批次的异质性,建议在灌装过程中进行抽样。 鉴于产品的吸湿性很强,规定了特殊的预防措施。 其原理是在整个灌装过程中定期等量取样。 混合这些连续的样品,均质化,然后采集实验室样品。 [外文原描述]: The procedures are applicable to crude or refined products in the course of filling, or to products already contained in drums or in transportable or fixed tanks. Owing to the heterogeneity of the lots it is recommended to adopt the sampling during filling. Specifies particular precautions in view of the very hygroscopic nature of the product. The principle consists in samplings, at regular intervals, of equal quantities throughout filling. Mixing of these successive samples, homogenization and then taking the laboratory samples.
