Understanding ISO Codes

By Brad Bainbridge on Thu, Feb. 25, 2021

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.Screen Shot 2021-02-23 at 2.50.37 PMIt 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

By Brad Bainbridge on Tue, Nov. 29, 2016

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 gal ) of ISO VG 32 fluid with a flow rate of 25 lpm (6.6 gpm ).Through observing the manufacturer’s sampling practices, discussing fluid handling best practices and interpreting their lab reports, three independent problems were identified:

Why You Need to Care About Micro-Dieseling

By Scott Howard on Mon, Jan. 27, 2014

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

By Aaron Hoeg on Wed, Nov. 14, 2012

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 as :
