SIST EN 378-4:2017/kFprA1:2019

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.

Overview

SIST EN 378-4:2017/kFprA1:2019 is a European Standard developed by CEN that outlines safety and environmental requirements for the operation, maintenance, repair, and recovery of refrigerating systems and heat pumps. This standard applies to stationary and mobile systems of all sizes, including secondary cooling and heating systems. It also covers refrigerant recovery, reuse, and disposal to minimize risks to persons, property, and the environment.

The scope of SIST EN 378-4:2017/kFprA1:2019 includes:

• Operation and servicing of refrigerating systems and heat pumps
• Maintenance and repair activities for safety and environmental protection
• Procedures for refrigerant recovery and handling of refrigerant oils and heat-transfer fluids
• Compliance with national, EU, and international regulations relating to refrigerants, including fluorinated greenhouse gases

This standard is applicable to new systems, extensions, modifications, and transfers but excludes motor vehicle air conditioners and refrigeration systems manufactured before its publication, except when modified after publication.

Key Topics

1. Safety and Environmental Protection

• Detailed requirements to safeguard personnel and prevent property damage
• Guidelines to minimize environmental impact by controlling refrigerant leaks and proper disposal

2. Operation and Maintenance Procedures

• Instructions for routine inspections, leak detection, and pressure testing
• Specific guidance on maintenance after repairs, system relocations, or refrigerant conversions
• Responsibilities for record keeping of refrigerant usage, recycling, and servicing activities

3. Repair and Recovery Requirements

• Protocols for safe repair methods and verification of system integrity
• Requirements for refrigerant recovery, reuse, and disposal to avoid atmospheric emissions
• Inspection frequencies based on system size and refrigerant type (including CO2 equivalent regulations)

4. In-Service Inspection and Testing

• Visual inspection, pressure testing, and leakage testing procedures
• Recommended inspection frequencies based on refrigerant charge and global warming potential (GWP)
• Requirements for installation and maintenance of leak detection systems for large refrigerant charges
• Safety device testing intervals and functional checks

5. Regulatory References and Amendments

• Alignment with EU Regulation (EU) 517/2014 on fluorinated greenhouse gases
• Reference to ISO 817 for refrigerant safety classification
• Incorporation of national regulations and recommended practices for environmental compliance

Applications

SIST EN 378-4:2017/kFprA1:2019 targets industries and professionals involved in the design, installation, operation, and servicing of refrigerating systems and heat pumps, including:

• Commercial and industrial refrigeration units
• HVAC systems incorporating heat pump technology
• Cold storage and secondary cooling/heating systems
• Service companies performing maintenance, repair, and refrigerant recovery
• Environmental compliance officers ensuring adherence to emissions regulations

By following this standard, organizations can ensure safe, efficient, and environmentally responsible handling of refrigerants and system components, reducing risks and regulatory liabilities.

Related Standards

For comprehensive compliance and system safety, EN 378-4 should be used in conjunction with other parts of the EN 378 series and relevant standards, including:

• EN 378-1:2016 - Basic safety and environmental requirements, refrigerant classification
• EN 378-2:2016 - Design and construction safety requirements for refrigerating systems
• ISO 817 - Safety classification of refrigerants
• EN 60335 Series - Safety of electrical appliances, relevant to unitary refrigerating systems
• EU Regulation 517/2014 - Control of fluorinated greenhouse gases (F-gases)

Compliance with these standards and regulations ensures holistic safety management and environmental protection throughout the lifecycle of refrigerating systems and heat pumps.
