Refrigerating systems and heat pumps - Competence of personnel
This European Standard defines the activities related to refrigerating circuits and the associated competence
profiles and establishes procedures for assessing the competence of persons who carry out these activities.
NOTE: As a refrigeration circuit is considered not to incorporate electrical and electronical systems activities in this area
are not part of this standard. For competences on electrical and electronical systems see EN 50110.
This European Standard does not apply to persons carrying out work on self contained refrigerating systems
as defined in EN 378-1 from the initial design of the product to the complete manufacture of the product
provided the process is controlled and the methods used are checked by an organisation or individual
responsible for the compliance with statutory requirements of health, safety and environment.
Kälteanlagen und Wärmepumpen - Sachkunde von Personal
Diese Europäische Norm definiert die Tätigkeiten im Zusammenhang mit Kältemittelkreisläufen sowie die zugehörigen Sachkundeprofile und legt die Vorgehensweise zum Beurteilen der Sachkunde von Personen fest, die diese Tätigkeiten ausführen. ANMERKUNG Da von einem Kältemittelkreislauf angenommen wird, dass er keine elektrischen und elektronischen Systeme einschließt, sind Tätigkeiten in diesem Bereich kein Bestandteil der vorliegenden Norm. Bezüglich der Sachkunde zu elektrischen und elektronischen Systemen ist es erforderlich, auf die nationalen Bestimmungen oder die zutreffenden Europäischen oder nationalen Normen zu verweisen. Diese Europäische Norm gilt nicht für Personen, die Arbeiten an Kältesätzen nach EN 378-1, von der Vorplanung des Produkts bis zur kompletten Fertigstellung des Produkts verrichten, sofern der Ablauf von einer Organisation oder Einzelperson überwacht und die angewendeten Verfahren von dieser überprüft wird, die für das Einhalten der gesetzlichen Anforderungen an Gesundheit, Sicherheit und Umwelt verantwortlich ist.
Systèmes de réfrigération et pompes à chaleur - Compétence du personnel
La présente Norme européenne définit les activités liées aux circuits de réfrigération ainsi que les profils de compétences associés et elle établit des procédures permettant d’évaluer les compétences des personnes qui réalisent ces activités.
NOTE Un circuit de réfrigération étant sensé ne pas comporter de systèmes électriques et électroniques, les activités entrant dans ce domaine ne font pas partie de la présente norme. Pour les compétences en matière de systèmes électriques et électroniques, voir l’EN 50110.
La présente Norme européenne ne s'applique pas aux personnes intervenant sur des systèmes de réfrigération autonomes définis dans l’EN 378-1, de la conception initiale à la fabrication finale du produit si le processus est commandé et si les méthodes employées sont contrôlées par un organisme ou une personne responsable de la conformité aux exigences statutaires de santé, sécurité et environnement.

Introduction Refrigerating systems, if not properly constructed, installed, operated and maintained, can be of danger to the health and safety of persons, the safety property, be detrimental to the environment and increase the energy consumption. It is therefore essential that personnel dealing with such systems are competent to carry out the activity, or activities, listed in this standard. These activities cover the particular sectors in which they may operate from original design to final dismantling and disposal. As job descriptions can vary from country to country and from company to company, this standard specifies the activities to be carried out. Job descriptions should specify these activities. This standard defines the activities related to the refrigerating circuit. SIST EN 13313:2012
