What 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 calibrating the instruments and verifying their correct operation both in the laboratory and in service.
In general, the techniques described in ISO 21018-4 are suitable for monitoring:
The general cleanliness level in hydraulic systems
The progress in flushing operations
Support equipment and test rigs
The use of this method is applicable to single-phase liquid systems only.
