This method determines cloud point using a step-wise cooling technique that is executed through automated equipment types with optical detection mode. This method is an alternative to the normal, manual technique.[1] It is a generic method that covers existing automated equipment. The present method covers distillate fuels, fatty-acid methyl esters (FAME) and paraffinic diesel fuels, including blends thereof, as well as those containing flow-improvers or other additives, intended for use in diesel engines and domestic heating installations NOTE 1 This method may be applicable for other products such as vegetable oils but these kind of products have not been evaluated during the inter-laboratory study NOTE 2 The inter-laboratory program consisted of petroleum products of ISO 2049[2] color of 5,0 and lower. The precisions stated in this test method may not apply to samples with color determined according to ISO 2049 higher than 5,0.
