2 Introduction Portable Fluid Analysis Kit The Donaldson - Portable Fluid Analysis Kit was developed to enable a person to conduct immediate on-site oil analysis in as little as minutes. Using the Patch Test Method, a user can reliably assign a three-digit cleanliness code to any given sample based on photomicrograph comparisons of known samples. These known samples are the results of of particle counts achieved by standards as set forth in ISO The kit effectively monitors particulate contamination in all hydrocarbon-based hydraulic fluids, bulk chemicals, and lubrication fluids. Simply pull a ml fluid sample through a Patch Membrane Filter and compare oil sample particle distribution with the Fluid Cleanliness Comparison Guide to assign an ISO Cleanliness Code. For complete Operating Instructions, see page 8 (operating manual). Particle Count can be determined in as little as minutes.

Greater Than Size Particle Count Code 7,0 0,000-0,000, 80,000-0,000 9,999,000,000-0,000,0 This sample is highly contaminated with silica,metallic, rust and carbon (such as coal) particles.

12 Types of Contamination Silica Most commonly sand or dust associated with airborne contamination containing hard, translucent particles Magnification: 0 x Scale: Division = µm Bright Metal Most commonly products of component wear and fluid breakdown within the system. Visible contaminant will usually appear to contain shiny metallic particles of various colors

13 f l u i d c l e a n l i n e s s c o m p a r i s o n g u i d e Types of Contamination c o n t i n u e d Black Metal Most commonly products of component wear within the system. Contaminants are primarily oxidized ferrous metal particles. Magnification: 0 x Scale: Division = µm Rust Most commonly seen when water is present in the system. Contaminants contain dull orange or brown particles.

14 Types of Contamination c o n t i n u e d Fibers Most commonly generated by paper products and fabrics. Sources of contamination also include cellulose filter media and shop rags Magnification: 0 x Scale: Division = µm Cake of Fines/ Precipitate A very high concentration of silt-size particles and/or additive package ingredients will build up on the patch membrane obscuring all other contaminants. If the additive package breaks down in this way and drops out of solution (uniform size and color), it is no longer performing its intended function.

15 Types of Contamination c o n t i n u e d Gel Cake A dense accumulation on the analysis membrane that makes particle contamination evaluation an impossibility. Magnification: 0 x Scale: Division = µm Note: All images contained in this guide are for comparison and evaluation purposes only. Actual results will vary depending upon specific conditions and levels of contaminants.

Cleanliness Code The ISO Cleanliness Code references the number of particles greater than,, & microns in one milliliter of fluid. The results of particle counting are plotted on the adjacent logarithmic graph. The corresponding ISO Code, shown above, gives the cleanliness code number for each of the three particle sizes.

18 Viscosity Classification Equivalents Each ISO viscosity grade number corresponds to the mid-point of a viscosity range expressed in centistokes (cst) at 0 C. For example, a lubricant with an ISO grade of has a viscosity within the range of , the midpoint of which is. Rule-of-Thumb: The comparable ISO grade of a given product whose viscosity in SUS at 0 F is known can be determined by using the following conversion formula: 0 F = 0 C Many petroleum products are graded according to the ISO Viscosity Classification System, approved by the International Standards organization (ISO) A KINEMATIC VISCOSITIES cst/ 0 C cst/ 0 C ISO VG AGMA GRADES 7 SAE GRADES CRANKCASE OILS W W SEA GRADES GEAR OILS W 80W 7W Viscosities can be related horizontally only.
