NBN ISO 29945:2019

This document 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.
