The value is determined by adding iodine to the grease or oil until the ability of the grease or oil to chemically bind is stopped; essentially, the iodine number is how many grams of iodine were added per 100 grams of substance tested. A higher iodine number defines the level of unsaturated esters in the liquid, which could combine with other substances to produce a chemical bond. In unfavourable circumstances such as contaminated oil, high temperature or extended drain intervals, high levels of unsaturated organic esters, as found in rapeseed-based oils, will react and bind with other substances, e.g. oxygen, and can cause gumming and residues. Synthetic Esters: di-esters or polyol esters based on either vegetal or animal fats, Also named Carboxylic Acid Esters Two main families : - Di-esters (Dicarboxylic ester) - Poly-esters (TMP esters TriMethol Propane) Esters differ by the number of C atoms (chain length) and position of the bonds between the C atoms. Saturated esters do not have double/multiple bonds between C atoms and are therefore more resistant to aging than partially saturated esters.

HF6b: HEES partially saturated / unsaturated In contrast to saturated esters, partially saturated esters have Double / multiple bonds between C atoms. Depending on their number and position, these unsaturated bonds between the C atoms are instable. These bonds can detach themselves and form new bonds, thus changing the properties of those liquids (an aging mechanism). Synthetic Esters: di-esters or polyol esters based on either vegetal or animal fats, Also named Carboxylic Acid Esters Two main families: - Di-esters (Dicarboxylic ester) - Poly-esters (TMP esters TriMethol Propane) Minimum absolute pressure measured at inlet flange listed in catalogue should be multiplied by a factor 1.1 Maximum temperature +80 C Good seals compatibility. TriGlycerides, Natural esters based on glycerin - Rape-seed (colza) - Olive - Sunflower (tournesol) - Soja - Groundnut - Jojoba multiplied by a factor 1.1 No strainer for operation under 10 C Minimum temperature 20 C In some case, limit to 10 C depending on viscosity index (with or without pour point improver). Maximum temperature +70 C. In order to avoid accelerated aging of the fluid, tank temperatures above 60 C [140 F] should be avoided.

Dissolves water completely no possibility to drain off. No strainer for operation under 10 C Paper filter element is not acceptable Do not paint or paint with epoxy base the pump and the reservoir. Avoid any contamination, polyglycol being not mixable with mineral or vegetable fluids. (Maximum amount of foreign oil 1 %). Recommended seals are Viton (S5 compound). Incompatibility with steel/aluminium tribocontacts, polymethylmathacrylate (PMMA),NBR. HF6e: HEPR C >870 Kg/m 3 Viscosity typical > 140 to160 Polyalphaolefin PAO and Related hydrocarbon product Less biodegradable than most esters and vegetable based fluids. Can be mixed with mineral oil Bad seal compatibility (recommended seals Viton (S5 compound).

5 Page 5/5 Recommendations : Maximum content of water 0.05 %. Higher amount of water : drain off, or change fluid. Risk of condensation: for any kind of Mobile machinery install a water bleed off at the lowest point of the reservoir and drain off every 200 hours some samples of 1 litre. Return or pressure line filters. [Minimum recommended 20 10] Size 1.5 to 2 times larger than those for mineral oil base fluids. Oxidation during operation Change immediately the fluid, then flush properly the circuit. Change filters elements after 30 hours. Assembly Pump is installed on the circuit during more than 6 months without operation: manually turn shaft prior to pump starting up to make sure parts are not stuck. Fluid change Change fluid from mineral oil to one of these biodegradable fluids. Flush the circuit with one full reservoir filled of biodegradable fluid, then replace by a brand new fluid. Change filters elements after 30 hours of operation.
