Refrigerating systems and heat pumps - Safety and environmental requirements - Part 2: Design, construction, testing, marking and documentation
This European Standard specifies the requirements for the safety of persons and property, provides guidance for the protection of the environment and establishes procedures for the operation, maintenance and repair of refrigerating systems and the recovery of refrigerants.
The term "refrigerating system" used in this European Standard includes heat pumps.
This Part 2 of this Standard is applicable to the design, construction and installation of refrigerating systems including piping, components and materials. It includes ancillary equipment not covered in FprEN 378-1:2016, FprEN 378-3:2016 or FprEN 378-4:2016 which is directly associated with these systems. It also specifies requirements for testing, commissioning, marking and documentation. Requirements for secondary heat transfer circuits are excluded except for any protection requirements associated with the refrigerating system. Ancillary equipment includes, for example, fans, fan motors, electrical motors and transmission assemblies for open compressor systems.
This standard applies:
a) to refrigerating systems, stationary or mobile, of all sizes except to vehicle air conditioning systems covered by a specific product standard, e.g. ISO 13043;
b) to secondary cooling or heating systems;
c) to the location of the refrigerating systems;
d) to replaced parts and added components after adoption of this standard if they are not identical in function and in the capacity.
Systems using refrigerants other than those listed in Annex E of FprEN-378 1:2016 are not covered by this standard.
This standard does not apply to goods in storage.
This standard is not applicable to refrigerating systems which were manufactured before the date of its publication as a European Standard except for extensions and modifications to the system which were implemented after publication.
This standard is applicable to new refrigerating systems, extensions or modifications of already existing systems, and for existing stationary systems, being transferred to and operated on another site.
This standard also applies in the case of the conversion of a system to another refrigerant type, in which case conformity to the relevant clauses of parts 1 to 4 of the standard shall be assessed.

Overview
SIST EN 378-2:2017/oprA1:2019 is the Slovenian adoption of the European Standard EN 378-2:2016/prA1. It provides detailed safety and environmental requirements focused on the design, construction, testing, marking, and documentation of refrigerating systems and heat pumps. This standard is intended to ensure the safety of persons and property while also offering guidance for environmental protection. The requirements cover new installations, system extensions or modifications, and cases where systems are moved to a new location or converted to use a different type of refrigerant.
The standard is applicable to stationary and mobile refrigerating systems (including heat pumps) used in various industrial, commercial, and residential applications, with explicit exceptions such as vehicle air conditioning systems governed by other product standards.
Key Topics
- Design & Construction: Specifies criteria for selecting components and materials, as well as assembly procedures for refrigerant circuits and ancillary equipment. Requirements address the incorporation of heat exchangers, piping, compressors, pumps, and safety devices.
- Testing Requirements: Outlines procedures for strength and leak testing of system components prior to commissioning. Stringent acceptance criteria are set for detecting potential refrigerant leaks, based on the global warming potential (GWP) of the refrigerants used.
- Marking & Documentation: Defines essential marking practices for components and systems to ensure traceability and compliance. Documentation requirements encompass system design, installation records, test results, and safety information for operation and maintenance.
- Environmental Protection: Includes guidance on minimizing refrigerant emissions and safe recovery methods, supporting broader efforts in environmental sustainability.
- Safety Measures: Emphasizes hazards connected to refrigerant leaks, flammable concentrations, risks of mechanical damage, and electrical safety. Additional requirements are defined for systems sited in confined spaces or using refrigerants of specific classes.
Applications
SIST EN 378-2:2017/oprA1:2019 is widely used across several sectors where refrigerating systems and heat pumps are essential:
- Commercial and Industrial Refrigeration: Includes cold storage, food processing facilities, supermarkets, and industrial cooling plants.
- Building HVAC Systems: Applies to commercial, institutional, and residential buildings employing chillers, air handling units, and centralized heat pumps.
- Process Cooling and Heating: Used in manufacturing sectors requiring controlled environments, such as pharmaceuticals or electronics.
- Retrofit and Upgrades: Ensures ongoing compliance and safety when systems are modified, extended, or relocated.
The standard applies to secondary cooling or heating systems and any replaced or upgraded components, provided these are not functionally identical to those they replace.
Related Standards
SIST EN 378-2:2017/oprA1:2019 is part of a broader suite of European standards governing refrigerating systems and heat pumps:
- EN 378-1:2016 - Basic definitions, classification, and selection criteria for refrigerating systems.
- EN 378-3:2016 - Installation requirements for safety, operation, and maintenance.
- EN 378-4:2016 - Safe operation, maintenance, repair, and recovery of refrigerants.
- EN ISO 10675-1/2 - Non-destructive radiographic testing of welds.
- EN 14276-1/2 - Pressure vessels for refrigerating systems and components.
- EN 60335-2-34, EN 12693 - Safety requirements for compressors.
- EN ISO 4126 - Pressure relief devices.
- EN 60079 series - Equipment for explosive atmospheres (electrical safety).
Compliance with SIST EN 378-2:2017/oprA1:2019 helps organizations meet legal and regulatory obligations, boost operational safety, and align with best environmental practices in refrigeration and heat pump technology.
For system designers, installers, and operators, following this standard minimizes risks, enhances reliability, and supports environmental sustainability throughout the lifecycle of refrigerating systems.
