SIST EN ISO 22712:2023 PDF

Overview

EN ISO 22712:2023 (ISO 22712:2023) - "Refrigerating systems and heat pumps - Competence of personnel" - specifies competence criteria and activity profiles for personnel working on refrigerating systems and heat pumps. The standard aligns activities with ISO 5149 and EN 378 series requirements and covers the refrigerating circuit lifecycle from design to dismantling. It clarifies required competence levels, assessment procedures and normative criteria, while excluding electrical/electronic tasks and not constituting a training programme.

Key Topics

• Scope and exclusions
  • Covers activities related to refrigerating systems and heat pumps (design, installation, commissioning, maintenance, leak checking, dismantling, refrigerant removal).
  • Excludes electrical/electronic systems and work on self‑contained manufactured products under controlled processes.
• Activity definitions
  • Clear definitions for tasks such as designing, pre‑assembling, installation, putting into operation, commissioning, operating, in‑service inspection, leak checking, circuit maintenance, decommissioning and removal of refrigerant.
• Competence levels
  • Four levels: Basic Appreciation (BA), Working Knowledge (WK), Fully Operational (FO), Leading Edge (LE) - used to match personnel skills with job roles.
• Assessment and criteria
  • Annex A provides normative criteria for evaluation of competence; Annex B gives application guidelines.
  • Includes informative annexes with assessment examples for refrigerant families (HFCs under EU Regulation 517/2014), specific refrigerants (R717 - NH3, R744 - CO2) and flammable refrigerants.
• Terminology & references
  • Uses terms from ISO 5149/EN 378 and references ISO/IEC 17024 style definitions for assessment.

Applications

• Employers and HR managers in HVACR, refrigeration and heat‑pump sectors use EN ISO 22712:2023 to:
  • Define job descriptions and required competence for technicians, engineers and operators.
  • Develop assessment schemes and competency matrices for installation, commissioning, leak checking, maintenance, and decommissioning tasks.
  • Support compliance with safety, environmental and refrigerant‑handling regulations (e.g., fluorinated greenhouse gases rules).
• Certification bodies and training providers can use the competence criteria to design assessments and validation approaches (note: the standard itself is not a training syllabus).
• Designers, service contractors and regulators use the standard to ensure personnel meet consistent competency expectations across refrigerating systems and heat-pump applications.
