Petroleum products — Total sediment in residual fuel oils — Part 2: Determination using standard procedures for ageing

The principle of the method specified is determining the total sediment after accelerated ageing according to two procedures: A – thermal ageing (at 100 °C for 24 h), B – chemical ageing (dilution with hexadecane, heating to 100 °C for 1 h), followed by hot filtration as specified in ISO 10307-1. The object is to predict fuel oil stability to sedimentation during storage and handling.
