Understanding ISO Codes
ISO Cleanliness Codes Explained
The ISO Cleanliness Code (per ISO4406-1999) is used to quantify particulate contamination levels per milliliter of fluid at 3 sizes - 4µ, 6µ, and 14µ. It is expressed in 3 numbers (example 19/17/14) where each number represents a contaminant level code for the correlating particle size. The code includes all particles of the specified size and larger.
It is important to note that each time a code increases, the quantity range of particles is doubling. Inversely, as a code decreases by one the contaminant level is cut in half.

Hydraulic Valve Performance Test Stands and Clean Oil
The Application
A hydraulic valve manufacturer required pristine fluid (< 14/12/9) to test flow across an 80-micron orifice on their test stand. Gross amounts of contamination in the fluid would skew the test results, invalidating any data collected.
The system held 100 l (26.4

Why You Need to Care About Micro-Dieseling
Most people are familiar with diesel engines and how they work, which includes a rapid compression of air. When you inject a fuel source, it creates an explosion. Did you know that micro-dieseling is similar? A front-end loader that runs a diesel engine is a macro-level (or big picture) of what it does on the micro (or smaller) level in a hydraulic pump.

Hydraulic Oil Water Removal
Water, it's a compound that is required for practically everything on the earth. But within a lubrication or hydraulic system, it's one of the most damaging contaminants possible. Unfortunately, it's also one of the most common contaminants you'll find in your system.
When your lubrication or hydraulic system is continuously or even periodically exposed to high water levels, it can result in a mountain of damage. You can find evidence of water contaminant destruction if you look close enough. This damage appears
