DIN EN 1012-1:2011-02

This part of EN 1012 is applicable to compressors and compressor units having an operating pressure greater than 0,5 bar and designed to compress air, nitrogen or inert gases. This standard deals with all significant hazards, hazardous situations and events relevant to the design, installation, operation, maintenance, dismantling and disposal of compressors and 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; - any component or device which is necessary for operation. This part also covers the general requirements relating to process gas compressors; for specific requirements see the applicable DIN EN 1012-3. This part of DIN EN 1012 covers compressors driven by any power media, including battery powered, and which are fitted in or used with motor vehicles. This part of DIN EN 1012 does not cover requirements for compressors used in potentially explosive atmospheres. This part of DIN EN 1012 is not applicable to compressors which were manufactured before the date of publication of this document by CEN. The following modifications have been made with regard to DIN EN 1012-1:1996-07: This standard when published in 1996 applied to all types of compressors. The standard has now been divided into three parts with this part addressing compressors for compressed air, nitrogen and inert gases, a second part addressing vacuum pumps and a third part addressing compressors for process gases. It was considered a practical move so that if there were provisions that were laid down for compressors covered by CEN/TC 12 or ISO/TC 67, then any revision or amendments could be done to the process compressor part without affecting the provisions laid down for air compressors covered by this part of EN 1012. Standards dealing with non-safety aspects of compressor units are: - EN 61000-6-4 and EN 61000-6-2 for stationary compressor units; - EN 13309 for skid-mounted and mobile compressor units on electromagnetic compatibility.
