Compressors and vacuum pumps - Safety requirements - Part 3: Process compressors
This part of EN 1012 is applicable to compressors having an operating pressure greater than 0,5 bar and designed to utilise all gases other than air, nitrogen or inert gases which are covered in part 1. The standard lists the significant hazards associated with compressors and specifies safety requirements applicable to the design, installation, operation, maintenance and dismantling of compressors during their foreseeable lifetime and subsequent disposal. This part of EN 1012 includes under the general term compressors, those machines which comprise; - the compressor itself - a prime mover - any component or device supplied which is necessary for safe operation of the compressor. In addition it applies to partly completed compressors having a compressor in combination with some of these components as well as compressor assemblies operating in combination. Excluded are refrigerant compressors used in refrigerating systems or heat pumps as defined in EN 378-1.
Kompressoren und Vakuumpumpen - Sicherheitsanforderungen - Teil 3: Prozesskompressoren
Dieser Teil von EN 1012 gilt für alle Kompressoren, die einen Arbeitsdruck von mehr als 0,5 bar haben und so konstruiert sind, dass sie alle Gase mit Ausnahme von Luft, Stickstoff oder Inertgasen, die durch Teil 1 abgedeckt sind, benutzt werden können. Die Norm listet die von Kompressoren ausgehenden wesentlichen Gefährdungen auf und legt Sicherheitsanforderungen fest, die sich auf die Konstruktion, das Aufstellen, den Betrieb, die Wartung und das Demontieren von Kompressoren während ihrer voraussichtlichen Lebensdauer und ihrer darauf folgenden Entsorgung beziehen.
Dieser Teil von EN 1012 enthält unter dem allgemeinen Begriff Kompressoren Maschinen, die Folgendes umfassen:
den Kompressor selbst;
die Antriebsmaschine;
alle mitgelieferten Bauteile oder Geräte, die für den sicheren Betrieb des Kompressors notwendig sind.
Zusätzlich gilt dieser Teil von EN 1012 sowohl für teilweise zusammengesetzte Kompressoren, die einen Kompressor in Kombination mit einigen dieser Bauteile umfassen, als auch für Kompressoreinheiten, die in Kombination betrieben werden.
Ausgenommen sind in Kälteanlagen oder Wärmepumpen verwendete Kältemittel Verdichter, die in EN 378 1 festgelegt sind.
Compresseurs et pompes à vide - Prescriptions de sécurité - Partie 3 : Compresseurs de procédé
La présente partie de l’EN 1012 s’applique aux compresseurs ayant une pression de fonctionnement supérieure à 0,5 bar et conçus pour utiliser tous les gaz autres que l’air, l’azote ou les gaz inertes ; lesquels sont couverts par la partie 1. La norme répertorie les phénomènes dangereux significatifs associés aux compresseurs et précise les prescriptions de sécurité applicables à la conception, l’installation, le fonctionnement, la maintenance et le démontage des compresseurs au cours de leur vie prévue et de leur mise au rebut consécutive.
Sous le terme général compresseurs, la présente partie de l’EN 1012 comprend les machines incluant :
le compresseur en lui-même,
un moteur d’entraînement,
tout composant ou dispositif fourni nécessaire pour une utilisation sûre du compresseur.
De plus, elle s’applique aussi aux compresseurs partiellement complets disposant d’un compresseur en association avec un ou plusieurs de ces composants ainsi qu’aux assemblages de compresseurs fonctionnant en combinaison.
Les compresseurs frigorigènes employés dans les systèmes de réfrigération ou les pompes à chaleur tels que les définit l’EN 378-1 sont eux exclus.

Foreword
This document (prEN 1012-3:2008) has been prepared by Technical Committee CEN/TC 232 “Compressors -
Safety”, the secretariat of which is held by SIS.
This document is currently submitted to the CEN Enquiry.
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 Manchinary Directive.
For relationship with EU Directive, see informative Annex ZA, which is an integral part of this document.
Part 1: Air compressors
Part 2: Vacuum pumps
Part 3: Process compressors
Introduction
This document is a type C standard as stated in EN ISO 12100-1.
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 EN 1012-1 was published in 1996, it applied to all types of compressors. Aspects related to process
compressors are now moved into this part 3 of the EN 1012 series. 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.
1 Scope
This part of EN 1012 is applicable to compressors having an operating pressure greater than 0,5 bar and
designed to utilise all gases other than air, nitrogen or inert gases which are covered in part 1. The standard
lists the significant hazards associated with compressors and specifies safety requirements applicable to the
design, installation, operation, maintenance and dismantling of compressors during their foreseeable lifetime
and subsequent disposal.
This part of EN 1012 includes under the general term compressors, those machines which comprise;
the compressor itself
a prime mover
any component or device supplied which is necessary for safe operation of the compressor.
In addition it applies to partly completed compressors having a compressor in combination with some of these
components as well as compressor assemblies operating in combination.
Excluded are refrigerant compressors used in refrigerating systems or heat pumps as defined in EN 378-1.
