标准范围

ISO 29945:2016规定了装货港和卸货港码头冷冻液化二甲醚的手动取样方法以及注意事项。ISO 29945:2016不包括管线或容器中取样点位置的建议。ISO 29945:2016也适用于以下情况，并进行了必要的修改:-液化气罐车上二甲醚的取样（如果提供了适当的取样装置）；-对化学和物理性质与二甲醚相似的其他冷冻、非石油基液化气体燃料进行取样。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，它们的基本特性彼此相似，因此本文件一般参考了许多国家已采用的液化石油气预防措施。关于质量方面的预防措施，也可参考本文件中相应的单独项目。

ISO 29945:2016 specifies a manual sampling method for refrigerated liquefied DME at terminals in both loading and unloading ports along with precautions.ISO 29945:2016 does not include recommendations for the location of a sampling point in a line or vessel.ISO 29945:2016 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.
