This International Standard specifies a procedure of test for high temperature (105°C) evaporation residue in DME used as fuel by the mass analysis method. This procedure is applicable to determine the amount of high temperature (105°C) evaporation residue up to the value specified in ISO16861.
Several tests can be applied to determine amount of evaporation residue in liquefied products. Among them, this International Standard specifies the method that has detection limit sufficient for a DME specification in ISO16861, using less resource compared to other methods.
When more precise quantitative test is required, use of ISO13757 instead of this International Standard is recommended.
Because of the procedure applied, the evaporation residue which has a boiling point lower than 105°C will not be determined.
NOTE The precision of this method has been studied for a limited set of samples and content levels by a limited amount 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.
