该欧洲标准适用于工作气体压缩机和工作气体压缩机单元，其工作压力大于0.5巴（表压），输入轴功率大于0.5kW，并且设计成压缩除空气，氮气或空气以外的所有气体惰性气体在第1部分中介绍。本文件涉及与过程气体压缩机和过程气体压缩机单元的设计，安装，操作，维护，拆除和处理有关的所有重大危险，危险情况和事件，当它们用作意图和在制造商合理预见的误用条件下（见第4条）。 EN 1012的这一部分包括一般术语压缩机单元，这些机器包括: - 压缩机; - 包括原动机的驱动系统; - 提供操作所需的任何组件或设备。 EN 1012的这一部分不适用于在CEN发布本文件之前制造的压缩机。 本欧洲标准的要求不考虑压缩机/压缩机单元与现场进行的其他过程之间的相互作用。 排除的是: - 用于制冷系统或热泵的制冷剂压缩机，其安全性

This European Standard is applicable to process gas compressors and process gas compressor units having an operating pressure greater than 0,5 bar (gauge), 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, dismantling 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 comprise: - 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 safety requirements are given in EN 60335-2-34 or EN 12693; - the specification of performance levels and/or safety integrity levels for safety related parts of control systems. Performance levels and/or safety integrity levels are an important aspect of compressor design and should be determined by the manufacturer and the user based on a risk assessment (see Introduction). This European Standard does not cover those safety aspects of road transport dealt with by EC legislation for trailers.
