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 0-999. 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.

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.
Types of Contamination c o n t i n u e d Gel Cake 0 0 0 0 0 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.

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 8.8 -., 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: SUS @ 0 F = cst @ 0 C. 0 0 0 0 0 8 Many petroleum products are graded according to the ISO Viscosity Classification System, approved by the International Standards organization (ISO). 000 000 70 8000 0 00 000 00 0 00 8A 0 000 800 000 0 80 8 00 000 00 00 00 00 0 80 KINEMATIC VISCOSITIES cst/ 0 C cst/ 0 C 0 0 9 8 7 ISO VG 0 0 0 0 0 8 7 AGMA GRADES 7 SAE GRADES CRANKCASE OILS 0 0 0 0 W W SEA GRADES GEAR OILS 0 90 8W 80W 7W Viscosities can be related horizontally only.
