ISO 16332:2018规定了在规定和简化的实验室条件下进行的油水分离器对比试验。 本试验适用于压力侧燃油/水分离器以及吸入侧燃油/油水分离器。使用相同的测试装置布局，用细液滴测试压力侧燃油/水分离器，用粗液滴测试吸入侧过滤器。 额定流量（单位:升/小时）适用于50升/小时至1500升/小时的范围。根据客户和油水分离器制造商之间的协议，经过一些修改，该程序可用于流量较高或较低的油水分离器。

ISO 16332:2018 specifies a fuel/water separator comparison test under defined and simplified laboratory conditions. This test is intended for pressure side fuel/water separators as well as for suction side fuel/water separators. Pressure side fuel/water separators are tested with fine droplets and suction side filters are tested with coarse droplets using the same test rig layout. The rated flow (in litres per hour) is intended for the range between 50 l/h and 1 500 l/h. By agreement between customer and fuel/water separator manufacturer, and with some modifications, the procedures can be used for fuel/water separators with higher or lower flow rates.
