6、s specifications meeting the essential requirements set out in Annex I of the “Machinery Directive”, Directive 2006/42/EC, and which apply to machines that are either first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of compliance with the essential
7、requirements of the directives. Once this standard is cited in the Official Journal of the European Union, it is deemed a “harmonized” standard and thus, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (“presumption of conformity”). The Eu

Amendments This standard differs from DIN EN 1012-2:1996-07 as follows: a) the standard has been brought in line with the re
9、quirements of the new Machinery Directive 2006/42/EC; b) normative references have been updated; c) Annex ZA (informative) “Relationship between this European Standard and the Essential Requirements of EU Directive 98/37/EC” has been updated. d) Annex ZB (informative) “Relationship between this Euro

When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take prec
31、edence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard.“ DIN EN 1012-2:2011-12 EN 1012-2:1996+A1:2009 (E) 5 1 Scope This standard is applicable to all vacuum pumps, vacuum pump combinations and vacuum pump
32、ing systems. The standard lists the significant hazards associated with vacuum pumps and specifies safety requirements applicable to the design, installation, operation, maintenance and dismantling of vacuum pumps during their foreseeable life and subsequent disposal. The scope does not include pump
33、s designed to pump continuously on open systems where the pump inlet pressure is above 75 kPA (750 mbar) absolute, i.e. vacuum cleaners, ventilation fans). Vacuum pumps intended for use in special applications shall also comply with any specific standards relating to those applications. 2 Normative

Definitions specifically needed for this standard are added below. 3.1 vacuum an environment where the
43、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“ a
44、nd “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
45、pressure at the vacuum pump outlet specified by the manufacturer DIN EN 1012-2:2011-12 EN 1012-2:1996+A1:2009 (E) 7 3.7 throughput of a vacuum pump quantity of gas flowing through the inlet of the vacuum pump, usually expressed as a pressure quantity product per unit time interval 3.8 pumped media a

47、ich has a maximum starting pressure or a maximum outlet pressure which is less than atmospheric pressure or is only efficient at lower pressures and is intended to operate in conjunction with a primary pump to produce pressures lower than could be achieved by the primary pump alone 3.12 pumping syst
