Abstract

Ïã¸ÛÁùºÏ²Ê¿ª½± 21018-4:2016 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 off-line in containers. It 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 Ïã¸ÛÁùºÏ²Ê¿ª½± 21018-4:2016 are suitable for monitoring

- the general cleanliness level in hydraulic systems,

- the progress in flushing operations, and

- support equipment and test rigs.

The use of this method is applicable to single-phase liquid systems only.
