Safety, reliability, and sustainability are at the heart of modern refrigerating technology. With industries ranging from food preservation to climate control and manufacturing, robust standards are crucial. This article offers a clear and accessible overview of three pivotal standards in the energy and heat sector: SIST EN 12693:2026, SIST EN 14276-1:2020, and SIST EN 378-2:2017. These standards provide critical guidelines on safety, environmental impact, and the technical integrity of refrigerating systems and heat pumps. For any business relying on refrigeration infrastructure, understanding and implementing these standards is essential for maximizing productivity, ensuring operational safety, scaling operations, and maintaining regulatory compliance.
Overview / Introduction
Refrigerating technology is a vital pillar in virtually every modern industry. From keeping our food safe to enabling precision manufacturing processes and comfortable living environments, the reliability of refrigerating systems is a public and business concern. With increasing energy demands, heightened environmental considerations, and the push for operational efficiency, international standards shape the way these technologies are designed, installed, and maintained.
This article walks you through three cornerstone standards, making technical language easy to grasp while explaining why these are non-negotiable for anyone serious about safe, productive, and future-ready operations. By the end of this guide, you’ll understand their practical requirements, who must comply, and how they can future-proof your organization.
Detailed Standards Coverage

SIST EN 12693:2026 sets out comprehensive safety and environmental guidelines for positive displacement refrigerant compressors used in both stationary and mobile refrigerating systems and heat pumps. Targeted toward commercial and industrial applications, this standard encompasses compressors with integral motors, covering open drive, semi-hermetic, and hermetic types up to specific voltage limits.
This standard is essential for designers, manufacturers, contractors, and users of refrigerating technology. It addresses significant hazards, including those related to mechanical strength, electrical safety, vibration, and the risk of pressure rupture. Also included are detailed manufacturing, testing, documentation, and marking requirements, ensuring that compressors perform safely throughout their lifecycle and under foreseeable misuses.
Scope and Application:
Covers compressors up to 1,000 VAC and 1,500 VDC, excluding those intended for household appliances, water/air refrigerants, and some automotive air conditioning.
Addresses open drive, semi-hermetic, and hermetic designs.
Excludes noise emission requirements, focusing instead on safety and reliability under operational and potential misuse conditions.
Key Requirements:
Protection of moving parts and prevention of compressor instability.
Strict manufacturing and testing procedures: pressure testing, type and individual strength/ tightness tests, and verification of electrical safety.
Mandatory marking, warnings, and user documentation for safe operation and maintenance.
Verification of safe design against mechanical, electrical, and thermal hazards.
Compliance with established safe industrial practices and relevant European directives.
Who Must Comply:
Manufacturers, designers, and assemblers of compressors for commercial and industrial refrigerating systems and heat pumps.
Any business or technician incorporating compressors into larger systems.
Practical Implications: Implementing this standard means greater safety for personnel, better protection for assets, and reduced liability. Businesses can expect fewer incidents, easier regulatory approval, and increased confidence among stakeholders and clients.
Key highlights:

SIST EN 14276-1:2020 – Pressure Equipment for Refrigerating Systems and Heat Pumps – Vessels, General Requirements
Full Standard Title: Pressure equipment for refrigerating systems and heat pumps – Part 1: Vessels – General requirements
SIST EN 14276-1:2020 focuses on the crucial pressure vessels integral to most refrigerating and heat pump systems. Pressure vessels safely contain refrigerant gases or liquids under pressure and are vital for the system’s integrity. This standard ensures that vessels are manufactured, tested, and documented to withstand the mechanical and thermal loads encountered in service.
It lays out strict material requirements, design calculations, welding and brazing specifications, testing protocols, and documentation mandates for pressure vessels operating down to -1 bar and up to 200 °C and 160 bar.
Scope and Application:
Applies to metallic, ductile pressure vessels in stationary refrigerating and heat pump systems.
Covers vessel manufacture, from material selection to final pressure/leak testing and documentation.
Excludes riveted, directly flame-heated, multi-layered, roll-bond, and certain other vessel types.
Key Requirements:
Rigorous material selection and documentation; prevention of brittle fracture.
Design for mechanical and corrosion loads, including mandatory safety margins.
Welding and brazing procedures, with detailed qualification and verification standards.
Complete inspection, pressure/leak testing, and marking before the vessel enters service.
User documentation with instructions, technical details, and a record-keeping system.
Who Must Comply:
Manufacturers of pressure vessels for refrigerating or heat pump systems
System integrators and contractors installing such vessels
Maintenance personnel responsible for pressure equipment safety
Practical Implications: Implementation guarantees vessel safety under extreme conditions, reduces risk of catastrophic failure, simplifies approval from authorities and insurers, and makes maintenance and expansion much easier.
Key highlights:
Applies to metallic, ductile stationary pressure vessels
Requires full design, material, and testing compliance
Minimizes risk of failure, ensuring safety and uptime

SIST EN 378-2:2017 – Refrigerating Systems and Heat Pumps – Safety and Environmental Requirements – Part 2: Design, Construction, Testing, Marking, and Documentation
Full Standard Title: Refrigerating systems and heat pumps – Safety and environmental requirements – Part 2: Design, construction, testing, marking and documentation
As the comprehensive standard governing the safety, environmental performance, and operational lifecycle of refrigerating and heat pump systems, SIST EN 378-2:2017 covers all aspects of system design, installation, maintenance, and modification—including piping, component selection, and commissioning protocols.
This part is fundamental for engineers, system designers, contractors, facility managers, and any business with refrigeration at its core. By focusing on the entire system rather than isolated components, it provides a systems-thinking approach to risk reduction, environmental integrity, and reliable performance.
Scope and Application:
Applies to new and modified stationary or mobile refrigerating and heat pump systems, except specific vehicle air conditioning.
Encompasses all piping, components, ancillary equipment, and site location factors.
Governs additions and upgrades to existing systems post-standard publication.
Does not apply to stored goods or older legacy systems, except for upgrades.
Key Requirements:
Robust design, construction, and component selection standards to minimize hazards.
Testing/certification for intrinsic safety, pressure resilience, and tightness.
Strict marking and documentation procedures for traceability and maintenance.
Clearly defined protocols for operating, commissioning, and converting to new refrigerants.
