BS ISO 29945:2016规定了在这两个区域的终端对冷冻液化二甲醚的手动取样方法 装卸港及注意事项。本文件不包括管线或容器中取样点位置的建议。本文件也适用于以下情况，但需进行必要的修改:在提供适当取样装置的情况下，在液化气罐车上对DME进行取样；其他冷藏、非石油基、液化气体燃料的取样 物理性能与二甲醚相似。二甲醚的详细化学和物理性质不同于液化石油气，这表明 二甲醚需要不同于液化石油气的预防措施。然而，它们的基本性质与 因此，本文件中一般参考了已发布的液化石油气预防措施 适用于许多国家。也可以参考本手册中相应的单独项目 与质量有关的预防措施文件。交叉引用: ISO 4257购买本文件时提供的所有现行修订均包含在购买本文件中。

BS ISO 29945:2016 specifies a manual sampling method for refrigerated liquefied DME at terminals in both loading and unloading ports along with precautions.This document does not include recommendations for the location of a sampling point in a line or vessel.This document is also applicable to the following cases, with necessary modifications:sampling of DME on board liquefied gas tankers where appropriate sampling apparatus is provided;sampling of other refrigerated, non-petroleum-based, liquefied gaseous fuels whose chemical and physical properties are similar to those of DME.The detailed chemical and physical properties of DME differ from those of LPG, which suggests that DME requires precautions different from those of LPG. However, their basic properties are similar to each other and so general reference is made in this document to precautions for LPG that have been applied in many countries. Reference can also be made to the appropriate individual items in this document for precautions concerning the quality.Cross References:ISO 4257All current amendments available at time of purchase are included with the purchase of this document.
