EN 378-4+A1:2020 Certification Guidelines Explained
Purpose and objectives
The SN EN 378-4+A1:2020 standard provides comprehensive guidelines aimed at ensuring the safety and environmental protection of refrigerating systems and heat pumps. It outlines the necessary requirements for the operation, maintenance, repair, and recovery of these systems, emphasizing the importance of safe practices in handling refrigerants. This standard also seeks to minimize the environmental impact of refrigerants and enhance the operational efficiency of heat pumps, aligning with sustainability goals in the energy sector.
Scope: who must comply
The EN 378-4+A1:2020 standard applies to a wide range of stakeholders in the refrigeration and heat pump industries. This includes manufacturers, installers, and service providers who work with refrigerating systems and heat pumps across various sectors such as commercial refrigeration, industrial cooling, and residential heating. Organizations involved in the Energy & Heat Transfer context must familiarize themselves with these guidelines to ensure compliance and promote safety in their operations.
How SN EN 378-4+A1:2020 relates to other standards
The EN 378-4+A1:2020 standard is part of a broader framework of standards that regulate refrigerants and heat pump systems. It complements other standards such as:
- ISO 13043: This standard provides guidelines for the assessment and classification of refrigerants, ensuring they meet safety and environmental criteria.
- ISO 817: This standard specifies the safety classification of refrigerants, helping to identify the appropriate handling measures according to their toxicity and flammability.
- SIA 382/1: This standard focuses on the installation of refrigeration systems, providing additional technical requirements and best practices.
Revision history and current status
The SN EN 378-4+A1:2020 standard was published by the Swiss Association for Standardization (SNV) in 2020. The most recent revision included updates to safety protocols and environmental guidelines, reflecting advancements in technology and changing regulatory landscapes. This version emphasizes the importance of stringent operational protocols and the need for documentation to ensure compliance with international standards.

Kälteanlagen und Wärmepumpen - Sicherheitstechnische und umweltrelevante Anforderungen - Teil 4: Betrieb, Instandhaltung, Instandsetzung und Rückgewinnung
Refrigerating systems and heat pumps - Safety and environmental requirements - Part 4: Operation, maintenance, repair and recovery
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 standard applies: a) to refrigerating systems, stationary or mobile, of all sizes including heat pumps; b) to secondary cooling or heating systems; c) to the location of the refrigerating systems; d) to parts replaced and components added after adoption of this standard if they are not identical in function and capacity. This standard does not cover "motor vehicle air conditioners" constructed according to product standards such as ISO 13043. Systems using refrigerants other than those listed in FprEN 378-1:2016, Annex E are not covered by this standard unless they have been assigned to a safety class according to ISO 817. This standard does not apply to goods in storage. This standard is not applicable to refrigeration systems and heat pumps 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. This Part 4 of the European Standard specifies requirements for safety and environmental aspects in relation to operation, maintenance, and repair of refrigerating systems and the recovery, reuse and disposal of all types of refrigerant, refrigerant oil, heat-transfer fluid, refrigerating system and part thereof. These requirements are intended to minimise risks of injury to persons and damage to property and the environment resulting from improper handling of the refrigerants or from contaminants leading to system breakdown and resultant emission of the refrigerant. Subclauses 4, 5.1.1 to 5.1.4, 5.2, 5.3.1, 5.3.3 and 6.6 of this European Standard are not applicable to unitary systems having a power cord, being factory sealed, and in conformance with EN 60335 series.
