BS ISO 17196:2014

This standard BS ISO 17196:2014 Dimethyl ether (DME) for fuels. Determination of impurities. Gas chromatographic method is classified in these ICS categories:

• 75.160.20 Liquid fuels
• 71.080.60 Alcohols. Ethers

This International Standard specifies a procedure of test for methanol, CO, CO₂, methyl formate, ethyl methyl ether, and hydrocarbons up to C₄, in DME used as fuel by the gas chromatography method. This procedure is applicable to determine the amount of methanol, CO, CO₂, methyl formate, ethyl methyl ether, and hydrocarbons up to C₄, up to the value specified in ISO 16861.

NOTE The precision of this method has been studied for a limited set of samples and content levels by a limited number of labs. It allows establishment of a quality specification of DME but cannot be considered as a full precision determination in line with the usual statistical methodology as in ISO 4259.
