‘lubricant’ means a product that is capable of reducing friction, adhesion, heat, wear or corrosion when applied to a surface or introduced between two surfaces in relative motion, or is capable of transmitting mechanical power. The most common ingredients are base fluids and additives;

(2)

‘base fluid’ means a lubricating fluid which flow, ageing, lubricity and anti-wear properties, as well as its properties regarding contaminant suspension, have not been improved by the inclusion of additive(s);

(3)

‘additive’ means a substance or mixture which primary functions are the improvement of one or several of the following aspects: flow, ageing, lubricity, anti-wear properties and contaminant suspension;

(4)

‘substance’ means a chemical element and its compounds in the natural state or obtained by any production process, including any additive necessary to preserve its stability and any impurity deriving from the process used, but excluding any solvent which may be separated without affecting the stability of the substance or changing its composition;

(5)

‘total loss’ means that the lubricant is fully released to the environment during use;

(6)

‘partial loss’ means that the lubricant is partially released to the environment during use and the non-released part can be recovered for re-processing, recycling or disposal;

(7)

‘accidental loss’ means that the lubricant is used in a closed system and can be released to the environment only incidentally and, after use, can be recovered for re-processing, recycling or disposal;

(8)

‘chainsaw oil’ means a lubricant that is used to lubricate the bar and chain on one or more types of chainsaw;

(9)

‘wire rope lubricant’ means a lubricant that is used to lubricate wire ropes which consist of several strands of metal wire held together to form a rope;

(10)

‘concrete release agent’ means a lubricant that is used in the construction industry to prevent freshly placed concrete adhering to a surface, usually plywood, overlaid plywood, steel or aluminium;

(11)

‘grease’ means a solid or semi-solid lubricant which contains a thickener in order to thicken or modify the rheology of the base fluid;

(12)

‘gear oil’ means a lubricant made specifically for transmissions, transfer cases, and differentials in automobiles, trucks, and other machinery;

(13)

‘stern tube oil’ means a lubricant used in the stern tube of a ship;

(14)

‘two-stroke oil’ means a lubricant used in two-stroke engines;

(15)

‘temporary protection against corrosion’ means a lubricant that is applied to a metal surface as a thin film in order to prevent water and oxygen from coming into contact with the metal surface;

(16)

‘hydraulic systems’ means a lubricant by means of which power is transferred in hydraulic machinery;

(17)

‘metalworking fluid’ means a lubricant designed for metalworking processes, such as cutting and forming, and whose main functions are cooling, reducing friction, removing metal particles, and protecting the work pieces, the tool, and the machine tool from corrosion.
