What SN EN 378-2:2017 covers

SN EN 378-2:2017 specifies requirements aimed at safeguarding persons and property, while also addressing environmental protection concerns in the context of refrigerating systems and heat pumps. The standard applies to the design, construction, and installation of these systems, including all relevant components like piping and materials. It also encompasses the operational aspects such as maintenance, repair, and the recovery of refrigerants. However, it explicitly excludes vehicle air conditioning systems, which are covered by specific product standards like ISO 13043, as well as certain secondary heat transfer circuits unless they pertain to the refrigerating system's protection. The standard also details requirements for ancillary equipment that supports these systems, such as electrical motors and fans.

Key requirements

• Safety Standards: Establishes safety protocols to protect personnel and property from risks associated with refrigerating systems.
• Environmental Protection: Provides guidelines for the safe recovery of refrigerants to minimize environmental impact.
• Design and Construction: Details essential criteria for the design, construction, and installation of refrigerating systems and their components.
• Testing and Commissioning: Outlines procedures for testing and commissioning systems to ensure they meet required safety and operational standards.
• Marking and Documentation: Specifies necessary labeling, marking, and documentation requirements for compliance verification.
• Maintenance Protocols: Includes guidelines for the regular maintenance and repair of systems to ensure ongoing safety and efficiency.

These requirements are typically audited through rigorous assessments that check for compliance with safety and environmental standards, ensuring adherence throughout the system lifecycle.

How to implement SN EN 378-2:2017

Implementing SN EN 378-2:2017 involves several key steps that organizations should follow to ensure compliance. First, conduct a gap analysis to identify areas where existing practices may fall short of the standard's requirements. Following this, organizations should develop comprehensive documentation that outlines procedures and policies in alignment with the standard. Training sessions should then be organized for staff involved in the design, operation, and maintenance of refrigerating systems to ensure they understand the new requirements. After staff training, an internal audit should be conducted to evaluate adherence to the standard, followed by a certification audit to achieve compliance. It’s important to note that a dedicated implementation guide can provide further details on each of these steps for a successful transition.
