3 Definitions For the purposes of this standard the definitions given in ENV 1070 and ISO 3529 apply. Definitions specifically needed for this standard are added below. 3.1 vacuum an environment where the total pressure is below the prevailing atmospheric level. NOTE Vacuum is usually measured as the absolute pressure of the residual gas expressed as Pascals (Pa) or millibar (mbar). 1 mbar = 100 Pa. 3.2 vacuum pump device for creating, improving and/or maintaining a vacuum. NOTE Terms "vacuum pump" and "pump" have the same meaning throughout this standard. 3.3 pump inlet port by which gas to be pumped enters the pump 3.4 pump outlet outlet or discharge port of a pump 3.5 maximum starting pressure maximum inlet pressure at which the vacuum pump may be started 3.6 maximum outlet pressure maximum pressure at the vacuum pump outlet specified by the manufacturer SIST EN 1012-2:2001+A1:2009

Reference to safety requirement 4.1.1 Generally applicable
a) Cutting and severing due to contact with moving parts such as drive belts, cooling fans, couplings, shafts and rotors; 5.1.1 b) Cutting and severing due to sharp edges such as sheet metal parts, crimped tubes and turbine blades; 5.1.1 and 5.1.4 c) Drawing in to a vacuum system; 5.1.1 d) Ejection of parts caused by implosion of any part of the pump or pumping system; 5.1.1 e) Ejection of parts caused by bursting of the vacuum system due to excess pressure caused by:  the incorrect direction rotation of the vacuum pump,  a blocked or restricted exhaust,  the faulty operation of a gas input to the vacuum system,  mechanical failure of components,  the reverse rotation of a pump when switched off under vacuum;5.1.1 and 7.3.1 f) Loss of stability when adding or removing accessories; 5.1.1 g) Loss of stability during transportation; 5.1.1 h) Loss of stability during lifting due to lack of lifting facilities; 5.1.1 SIST EN 1012-2:2001+A1:2009

4.6.1 Generally applicable a) Hazards resulting from exhausting of toxic gases or vapours being processed; b) Hazards resulting from inhalation of concentrations of oil mist from the exhaust of an oil sealed pump; c) Hazards resulting from any contact during pump maintenance with toxic breakdown/reaction products of lubricants, pump fluids or pumped media; d) Fire or explosion resulting from processing or exhausting flammable gases and vapours; e) Fire or explosion resulting from processing or exhausting oxidants; f) Fire or explosion resulting from processing pyrophoric gases; g) Fire resulting from the degradation of lubricating oil at high temperatures; h) Hazard resulting from a violent increase in pressure due to the decomposition of a pumped gas.
