Hydraulic fluid power. Monitoring the level of particulate contamination in the fluid - Use of the light extinction techniqueWhat is ISO 21018 4 Hydraulic fluid power about? ISO 21018 is a series on hydraulic fluid power. Hydraulic fluid power is the power derived from the energy of falling or fast running water. ISO 21018 4 specifies a method for the determination of the particulate contamination level using the light extinction technique (also known as light blockage or light obscuration) either online or offline in containers. ISO 21018 4 also defines procedures for
