BS ISO 16332:2018 pdf free.Diesel engines – Fuel filters – Method for evaluating fuel/water separation efficiency. As commercially available. For biodiesel and biodiesel containing fuels the direct Karl Fischer method Is recommended. Humidity is probably the largest source of error during the titration process. Special precautions shall be taken during setup and testing. The amount of water per sample should be S0 tg to reach a good relation between titration time and accuracy. 5.2.3.2 Centrifuge For higher water concentration as specified in 6.4.1. 20 000 ppm water concentration, a centrifuge according to can be used. The measurement accuracy according to Table 1 shall be confirmed. 5.2.4 Equipment for determination of IFT The equipment for determination of the interfacial tension shall be according to ISO 9101. 5.3 Test stand 5.3.1 General The test stand, shown diagrammatically In Figure 2. shall comprise a fuel/water separator test circuit as described in LiZ. All parts in contact with fuel, should be made of stainless steel. 5.3.2 Fuel/water separator test circuit 5.3.2.1 Fuel sump (1) The container with a conical bottom should be made of stainless steel. The fuel outlet shall be located at the lowest point of bottom. The container shall be able to…
