1. Analysis Reports

A. Spectrographic analysis

- is used to finely measure parts per million by weight (PPM) of various elements contained in sampled oil. The process measures the concentration of wear metals, contaminant metals and additive metals in a lubricant. • It can identify the concentration of individual metal or alloy of a particle. Its size limit is about 8 microns or smaller, so it is blind to the larger particles that can often signal pending failure. • Spectrographic limits are an instrument limitation. The size limitation depends on the particle types and instrumentation used. • Spectrographic Analysis and Particle Count Analysis form an efficient partnership in identifying the concentration of small and large particles in the oil and the total fluid contamination level.

B. Viscosity

- is the most important physical property of oil. Viscosity determination provides a specific number to compare to the recommended oil in service. An abnormal viscosity (± 15%) is usually indicative of a problem. Standard ISO VG 46 hydraulic oil should have a viscosity between 41 and 51.

C. Fourier Transform Infrared (FT-IR) Spectrometer

- Measures the chemical composition of a lubrcant. • Every compound has a unique infrared signature. Using a FT-IR Spectrometer, the key signature points in a spectrum of a specific lubricant are monitored. These signatures are usually common contaminants and degradation byproducts unique for a particular lubricant. • Molecular analysis of hydraulic fluids by FT-IR spectroscopy produces direct information on molecular species on interest, including additives, fluid breakdown products and external contamination. The infrared spectrum of used oil is compared to a baseline spectrum of new oil. Levels of oxidation, nitration and sulfate by-products are reported along with soot, water and glycol.

D. Particle Counts

- Measures the size and quantity of particles in a lubricant. Use whenever Hyster provides recommended lubricant cleanliness levels and for any system where oil cleanliness is directly related to longer lubricant life, decreased equipment wear or improved equipment performance. • The analysis report will show the actual number of particles by size category and by the ISO code per ISO 4406-1999. The ISO code reports 3 particle size categories: ≥ 4 microns / ≥ 6 microns / ≥ 14 microns • Use whenever Hyster provides recommended lubricant cleanliness levels and for any system where oil cleanliness is directly related to longer lubricant life, decreased equipment wear or improved equipment performance.

E. Water Content

- The Karl Fischer Test quantifies the amount of water in lubricant. • Results are reported as % water or PPM (1% = 10,000 PPM). • Water seriously damages the lubricating properties of oil and promotes component corrosion, Increased water concentrations indicate possible condensation, coolant leaks, or leaks around the seals.
