Overview

EN 732:1998 (CEN) specifies requirements for dedicated liquefied petroleum gas (LPG) absorption refrigerators. The standard covers constructional features, safety and operational requirements, test techniques, and marking for absorption refrigerators using commercial butane and propane. EN 732 applies to room-sealed (Type C11) and flueless (Type A11) appliances as referenced in CR 1749 and is intended for type testing of LPG absorption refrigerators. Because gas consumption for these appliances is comparable to pilot flames (maximum ~60 g/h), the standard does not include efficiency measurement.

Key topics and requirements

  • Scope and appliance types: Applies to absorption refrigerators fuelled by commercial butane/propane (LPG), specifically Type C11 (room sealed) and Type A11 (flueless) per CR 1749.
  • Constructional features: Requirements for mechanical and gas-side construction intended to ensure safe, reliable operation (materials, assembly, and basic design considerations are addressed).
  • Safety and operational requirements: Protective measures, gas safety features and operational criteria to reduce leak and combustion hazards in domestic and dedicated applications.
  • Test techniques: Procedures for type testing to verify compliance with safety and functional requirements (EN 732 focuses on type testing rather than routine production checks).
  • Marking: Mandatory marking and information for identification, safe installation and use.
  • Gas consumption note: Typical gas consumption is in the order of pilot flames, with a maximum of about 60 g/h; therefore energy-efficiency testing is not covered.

Applications and who uses it

EN 732 is relevant to stakeholders involved with LPG absorption refrigeration:

  • Manufacturers of LPG absorption refrigerators - for design validation and product type testing.
  • Testing laboratories and certification bodies - to perform and document type tests and conformity assessments.
  • Regulatory authorities and market surveillance - to assess compliance with safety and marking requirements.
  • Procurement and specification writers - for technical specifications when sourcing dedicated LPG absorption refrigerators for caravans, off‑grid cabins, or other applications where absorption cooling is required.
  • Installers and service technicians - for understanding marking and operational safety features required by the standard.

Related standards

  • CR 1749 - referenced for definitions of Type C11 and Type A11 appliances.
  • Other CEN/CENELEC standards on gas appliance classification and gas safety may be relevant when integrating EN 732 requirements into a broader compliance program.
