Compressors and vacuum pumps - Safety requirements - Part 3: Process compressors
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.

Diese Europäische Norm gilt für Prozessgaskompressoren und Prozessgaskompressoranlagen, die einen Arbeitsdruck von mehr als 0,5 bar (Überdruck) haben, eine Leistungsaufnahme an der Antriebswelle von mehr als 0,5 kW haben und so konstruiert wurden, dass sie alle Gase außer Luft, Stickstoff oder inerte Gase, die im Teil 1 behandelt werden, verdichten können. Dieses Dokument befasst sich mit allen signifikanten Gefährdungen, Gefährdungssituationen und Gefährdungsereignissen, die sich auf die Konstruktion, das Aufstellen, den Betrieb, die Wartung, das Demontieren und die Entsorgung von Prozessgaskompressoren und Prozessgaskompressoranlagen beziehen, wenn sie bestimmungsgemäß und unter Bedingungen von durch den Hersteller vernünftigerweise vorhersehbaren Fehlanwendungen verwendet werden (siehe Abschnitt 4).
Dieser Teil von EN 1012 enthält unter dem allgemeinen Begriff Kompressoranlagen Maschinen, die Folgendes umfassen:
den Kompressor;
ein Antriebssystem einschließlich der Antriebsmaschine;
alle mitgelieferten Bauteile oder Geräte, die für den Betrieb notwendig sind.
Dieser Teil von EN 1012 gilt nicht für Kompressoren, die vor dem Datum der Veröffentlichung dieses Dokuments durch das CEN hergestellt wurden.
Die Anforderungen dieser europäischen Norm berücksichtigen nicht die Wechselwirkungen zwischen dem Kompressor/der Kompressoranlage und anderen vor Ort ausgeführten Prozessen.
Ausgenommen sind:

Kompresorji in vakuumske črpalke - Varnostne zahteve - 3. del: Procesni kompresorji
Ta evropski standard se uporablja za procesne plinske kompresorje in procesne plinske kompresorske enote, katerih obratovalni tlak je večji od 0,5 bara, moč pogonske osi kompresorja je večja od 0,5 kW, zasnovani pa so za stiskanje vseh plinov, razen zraka, dušika ali inertnih plinov, ki so zajeti v 1. delu. Ta evropski standard obravnava vse pomembne nevarnosti, nevarne razmere in dogodke v zvezi z zasnovo, namestitvijo, delovanjem, vzdrževanjem, razstavljanjem ali odstranjevanjem procesnih plinskih kompresorjev in procesnih plinskih kompresorskih enot, kadar se uporabljajo v skladu s svojim namenom in pod pogoji pričakovane nepravilne uporabe, ki jih določa proizvajalec. Ta del standarda EN 1012 pod splošnim izrazom kompresorske enote vključuje vse stroje, ki jih sestavlja: – kompresor; – pogonski sistem, vključno s pogonskim strojem; – katera koli komponenta ali naprava, ki je potrebna za delovanje. Ta del standarda EN 1012 se ne uporablja za kompresorje, proizvedene, preden je CEN objavil ta standard. Zahteve tega evropskega standarda ne upoštevajo medsebojnega vpliva kompresorja/kompresorske enote in ostalih procesov, ki se izvajajo na mestu. Izključeni so: – hladilni kompresorji, ki se uporabljajo za hladilne sisteme ali toplotne črpalke, za katere so varnostne zahteve opredeljene v standardu EN 60335-2-34 ali EN 12693; – specifikacija ravni delovanja in/ali specifikacija ravni varnostne celovitosti za dele krmilnih sistemov, povezane z varnostjo. Ravni delovanja in/ali ravni varnostne celovitosti so pomemben del zasnove kompresorjev ter bi jih morala določiti proizvajalec in uporabnik na podlagi ocene tveganja (glej uvod). Ta evropski standard ne zajema varnostnih vidikov cestnega prometa, ki so obravnavani v zakonodaji ES za priklopna vozila.

The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated 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 according 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. Part 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.
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 of 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 safety.
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 applying appropriate preventive measures. These tasks are outside the scope of this standard.
