Understanding ISO Codes - The ISO cleanliness code (per ISO) is used to quantify particulate contamination levels per milliliter of fluid at 3 sizes. ISO (E). PDF disclaimer.

ISO specifies the code to be used in defining the quantity of solid particles in the fluid used in a given hydraulic fluid power system.

Noria Corporation Tags: oil analysis , particle counting The International Organization for Standardization ISO has developed a cleanliness code that is the primary piece of data reviewed on most industrial oil analysis reports.

The value of this code can help determine the overall cleanliness of the monitored system. Often times, an end user will establish a target value to achieve, thus offering a level of confidence so long as the used oil sample meets this established target.

The trend in the oil analysis world is to give too much credit to the value of the ISO cleanliness code. Some laboratories have even begun to only report the ISO code.

UNDERSTANDING ISO CODES

There is also a heavy reliance on this value by end-user analysts. The ISO code is a fantastic tool to use for setting target alarms and establishing a goal to achieve and maintain as it relates to system cleanliness.

It is also the perfect value to use for key performance indicator KPI tracking, charting and posting. However, the ISO code should play only a secondary role when it comes to evaluating used oil sample data. When sending a sample through an APC, particles are counted either through laser or pore blockage methods.

Although different laboratories may report different particle count micron levels, an example of the various reported micron levels includes those greater than 4, 6, 10, 14, 21, 38, 70 and microns. ISO is the reporting standard for fluid cleanliness.

According to this standard, a code number is assigned to particle count values derived at three different micron levels: greater than 4 microns, greater than 6 microns and greater than 14 microns. The ISO code is assigned based upon Table 1.

This can be seen in the example on the left. However, without seeing the raw data, the only thing the ISO code can positively identify is whether a sample has achieved the desired target value.

The ISO code does nothing to help determine any type of real trend information unless the value of the raw data at the given micron levels changes enough to raise or lower the ISO code. At each row, the upper limit for each code is approximately double that of the lower limit for the same code. ISO code number. Number of download this standard.
