This International Standard specifies a procedure of test for high temperature (105 °C) evaporationresidue in DME used as fuel by the mass analysis method. This procedure is applicable to determine theamount of high temperature (105 °C) evaporation residue up to the value specified in ISO 16861.Several tests can be applied to determine amount of evaporation residue in liquefied products. Amongthem, this International Standard specifies the method that has detection limit sufficient for a DMEspecification in ISO 16861, using less resource compared to other methods.When more precise quantitative test is required, use of ISO 13757 instead of this International Standardis recommended.Because of the procedure applied, the evaporation residue which has a boiling point lower than 105 °Cwill not be determined.This International Standard specifies a procedure of test for high temperature (105 °C) evaporationresidue in DME used as fuel by the mass analysis method.
