Overview
EN 378-2:2016/prA1 is the CEN European Standard addressing design, construction, testing, marking and documentation of refrigerating systems and heat pumps. It complements Parts 1, 3 and 4 by focusing on the physical assembly and verification of systems: piping, components, ancillary equipment and associated materials. The standard aims to protect persons and property, to support environmental protection and to establish procedures for operation, maintenance, repair and refrigerant recovery.
Key scope points from the standard:
- Applies to stationary and mobile refrigerating systems of all sizes (excluding vehicle air-conditioning covered by specific product standards).
- Covers new systems, extensions, modifications and systems transferred to another site.
- Includes ancillary equipment (fans, motors, transmission assemblies for open compressors, etc.) unless addressed in other EN 378 parts.
- Excludes secondary heat transfer circuit requirements except protections related to the refrigerant circuit.
- Does not apply to goods in storage or to systems manufactured before publication, except for modifications implemented after publication.
Key Topics
- Component and piping requirements: References to harmonized component standards (for example EN 14276 series, EN 13445) and explicit provisions for piping joints, flexible connectors and pressure-relief devices.
- Material and joining methods: Requirements for brazing, welding and permanent joints together with nondestructive testing obligations for a sample of joints.
- Testing and commissioning: Strength and tightness testing procedures are specified; for example, strength testing and site tightness tests are required before charging the plant, and acceptance criteria vary by refrigerant GWP class.
- Marking and documentation: Obligations for labelling of equipment, assembly documentation and retention of test records to support safe operation, maintenance and refrigerant recovery.
- Safety considerations: Measures for mechanical protection of flexible connectors, provisions for electrical equipment located in closed spaces where leak simulations indicate persistent flammable concentrations, and guidance on selection of components considering test pressures.
Applications
EN 378-2 is intended for manufacturers, system designers, installers, commissioning engineers and site operators. Practical uses include:
- Designing compliant refrigerant circuits and selecting certified components.
- Preparing site test procedures, pressure tests and tightness verification prior to charging.
- Documenting commissioning results and marking equipment for safe operation and maintenance.
- Assessing modifications, refrigerant conversions and system transfers to ensure continued conformity with safety and environmental requirements.
Related Standards
Relevant referenced standards and series include other parts of EN 378 and component/product standards such as EN 14276, EN 13445, EN 60204, EN 12799 and applicable EN ISO welding/NDT standards. Users should consult EN 378-1, -3 and -4 for broader system safety, refrigerant classification, and personnel requirements.
Practical value: By following EN 378-2:2016/prA1 organizations reduce safety risks, ensure regulatory alignment, facilitate refrigerant recovery and improve traceability across the lifecycle of refrigerating systems and heat pumps.

Die Norm SIST EN 378-2:2017/oprA1:2019 ist ein wesentlicher Bestandteil der europäischen Standards für Kühlsysteme und Wärmepumpen. Ihr Fokus liegt auf den Sicherheits- und Umweltanforderungen, die entscheidend für das Design, die Konstruktion, den Test, die Kennzeichnung und die Dokumentation dieser Systeme sind. Der Geltungsbereich dieser Norm ist umfassend und deckt Kühlsysteme und Wärmepumpen, sowohl stationär als auch mobil, in allen Größen ab, mit der Ausnahme von Fahrzeugsystemen, die speziellen Produktstandards unterliegen. Die Norm stellt sicher, dass die Schutzmaßnahmen für Personen und Eigentum sowie die Umweltanforderungen eingehalten werden, was für die Entwicklung von nachhaltigen Kühlsystemen unerlässlich ist. Durch die Spezifikation von Anforderungen für die Installation, einschließlich Rohrleitungen, Komponenten und Materialien, bietet die Norm einen klaren Leitfaden zur Einhaltung von Sicherheitsvorschriften. Eine der Stärken dieser Norm ist die prägnante Behandlung von Hu- компонента, die nicht in anderen Teilen der Norm abgedeckt sind. Dies beinhaltet zusätzliche Ausrüstung wie Ventilatoren und Motoren, die direkt mit Kühlsystemen verbunden sind. Die klare Definition und Abgrenzung der Anforderungen für Test, Inbetriebnahme und Dokumentation hilft, die Qualität und Sicherheit der Systeme zu gewährleisten. Ein weiterer positiver Aspekt der SIST EN 378-2:2017/oprA1:2019 ist ihre Anwendbarkeit auf bestehende Systeme sowie auf neue Konstruktionen. Dies ermöglicht eine einfache Anpassung und Integration in bereits bestehende Infrastrukturen, was insbesondere für die Umstellung auf umweltfreundlichere Kältemittel von Bedeutung ist. Die Norm fördert somit nicht nur die Sicherheit, sondern auch den nachhaltigen Betrieb von Kühlsystemen. Zusammengefasst bietet die SIST EN 378-2:2017/oprA1:2019 einen umfassenden, klaren und relevanten Rahmen für die Entwicklung, den Betrieb und die Wartung von Kühlsystemen und Wärmepumpen. Ihre umfangreichen Vorgaben zur Sicherheits- und Umweltkonformität machen sie zu einem wichtigen Leitdokument für Hersteller und Betreiber in diesem Bereich.
