This document (EN 1012-3:2013) has been prepared by Technical Committee CEN/TC 232 “Compressors, vacuum pumps” (Secretariat
5、: UNI, Italy). The responsible German body involved in its preparation was the Normenausschuss Maschinenbau (Mechanical Engineering Standards Committee), Working Committee NA 060-08-11 AA Prozessgaskompressoren of Section Kompressoren und Drucklufttechnik. Representatives of manufacturers and users
6、of compressors, and of the employers liability insurance associations contributed to this standard. This standard contains 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
7、 on the market or commissioned within the EEA. This standard serves to facilitate proof of compliance with the essential requirements of that directive. Once this standard is cited in the Official Journal of the European Union, it is deemed a “harmonized” standard and thus, a manufacturer applying t
8、his standard may assume compliance with the requirements of the Machinery Directive (“presumption of conformity”). The European Standards referred to in Clause 2 and in the Bibliography of the EN have been published as the corresponding DIN EN or DIN EN ISO Standards with the same number. Where the
9、International Standards referred to are not also DIN ISO Standards with the same number, there are no national standards available.

This European Standard shall be given the status of a
33、 national standard, either by publication of an identical text or by endorsement, at the latest by May 2014, and conflicting national standards shall be withdrawn at the latest by May 2014. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
34、rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relatio
35、nship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. EN 1012, Compressors and vacuum pumps, is composed of the following parts: Part 1: Air compressors; Part 2: Vacuum pumps; Part 3: Process compressors (the present document). The responsibility of CEN/TC
36、 232 includes coordination of safety standards with CEN/TC 182, Refrigerating systems, safety and environmental requirements, and CEN/TC 234, Gas infrastructure. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement
37、this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slov

The machinery concerned and the extent to which hazards, hazardous situations and events are covered are in
39、dicated in the scope of this document. When provisions of this type C standard are different from those which are stated in type A and B standards, the provisions of this type C standard take precedence over the provisions of the other standards for machines that have been designed and built accordi
40、ng to the provisions of this type C standard. When published in 1996, Part 1 of EN 1012 applied to all types of compressor. The standard is now divided into 3 parts with Part 1 addressing compressors for compressed air, nitrogen and inert gases and Part 3 addressing compressors for process gases. Pa
41、rt 2 continues to address vacuum pumps. Separating requirements for process gas compressors from those for compressors for air, nitrogen and other inert gases was considered a practical move so that the requirements for one type of compressor could be changed without affecting the complete standard.
42、 Where texts parts of EN 1012-3 are identical with EN 1012-1:2010, these are identified and formatted in italics. If common requirements for functional safety would be applied to all process compressors, the variety in the application of process compressors may cause significantly different levels o
43、f residual risk. Therefore, in addition to the requirements of this standard, the application of risk assessment may be required for safety related control systems in the case of particular applications to specify performance levels and/or safety integrity levels for related aspects of functional sa
44、fety. Informative Annex C has been included to provide guidance on risk assessment for related aspects of functional safety, including the determination of safety integrity levels and/or performance levels. The manufacturer of the compressor is responsible for carrying out such a risk assessment and
45、 applying appropriate preventive measures. These tasks are outside the scope of this standard. DIN EN 1012-3:2014-04 EN 1012-3:2013 (E) 7 1 Scope This European Standard is applicable to process gas compressors and process gas compressor units having an operating pressure greater than 0,5 bar (gauge)
46、, an input shaft power greater than 0,5 kW and designed to compress all gases other than air, nitrogen or inert gases which are covered in Part 1. This document deals with all significant hazards, hazardous situations and events relevant to the design, installation, operation, maintenance, dismantli
47、ng and disposal of process gas compressors and process gas compressor units, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). This part of EN 1012 includes under the general term compressor units those machines which c
48、omprise: the compressor; a drive system including the prime mover; any component or device supplied which is necessary for operation. This part of EN 1012 is not applicable to compressors which are manufactured before the date of publication of this document by CEN. The requirements of this European Standard do not take into account the interaction between the compressor/compressor unit and other processes carried out on site. Excluded are: refrigerant compressors used in refrigerating systems or heat pumps for which the safet
