General Information
- Abstract
This European Standard defines the constructional and operational characteristics, the safety requirements, test methods and the marking of regulators and automatic change-over devices having a maximum regulated pressure of 4 bar, with a maximum capacity of 150 kg/h, for use with butane, propane and their mixtures in the vapour phase.
This European Standard also applies to the safety devices which are included within regulating devices covered by this standard. The characteristics of these safety devices are given in Annexes A and B.
This European Standard also includes the requirements for:
- adaptors for connecting to self closing valves;
- auxiliary safety devices.
For the purpose of this European Standard:
- regulators and automatic change-over devices are referred to as "regulating devices";
- regulators, automatic change-over devices and adaptors are referred to as "devices".
The requirements apply to devices used in locations where the temperature likely to be reached during use is between -20 °C and +50 °C. Additional requirements for devices to be used at temperatures below –20 °C are given in Annex C.
Additional requirements for regulating devices intended to be used in caravans, motor caravans and freshwater boats are given in Annex D.
Additional requirements for regulating devices intended to be used in seawater boats are given in Annex M.
For specific use in caravans motor caravans and boats (freshwater and seawater), the automatic change over device function may also be carried out by an assembly of regulators, forming an "automatic change over device system" as defined in 3.1.9.
For installation rules of devices and their possible associated safety devices, reference should be made to national regulations in force in the member countries.
All connections and the countries in which they are used are given in Annexes G and H.
This European Standard defines only specific connections which are not defined in other standards (e.g. EN 15202 for cylinder valve connections).

Overview
EN 16129:2013 is the European standard governing pressure regulators, automatic change‑over devices, associated safety devices and adaptors for use with butane, propane and their mixtures in the vapour phase. It applies to devices with a maximum regulated pressure of 4 bar and a maximum capacity of 150 kg/h. The standard defines constructional and operational characteristics, safety requirements, test methods, marking, packaging and user instructions.
Key topics and requirements
- Scope and definitions: Clarifies terminology (regulating devices, devices, change‑over systems) and applicable gases and operating conditions.
- Design and constructional characteristics: Requirements for materials, sub‑assemblies (pressure sensing, regulation, back‑pressure, connections), mechanical strength and resistance to impact, pressure and corrosion.
- Performance requirements: Supply and regulated pressure ranges, flow performance, change‑over pressures and limits for different device types (regulators, automatic change‑over devices, variable and fixed regulators).
- Safety devices: Includes requirements for integrated safety features (over‑pressure relief valves, OPSO/UPSO, excess flow valves, regulated outlet pressure limiters). Annexes A and B give detailed characteristics for certain safety devices.
- Environmental and special use conditions: Devices are covered for normal use between -20 °C and +50 °C; Annex C provides additional requirements for temperatures below -20 °C. Annex D covers caravans, motor caravans and freshwater boats; Annex M covers seawater boats.
- Tests and verification: Type test methods, test gas and conditions, mechanical endurance, soundness, flow/pressure plotting and equivalence formulas are specified.
- Marking, packaging and documentation: Mandatory marking details, packaging and required installation/use/maintenance instructions are defined.
- Connections and adaptors: Lists national connector types in Annexes G and H; standard defines only connections not covered by other standards (see EN 15202 for cylinder valve connections).
Practical applications and users
EN 16129:2013 is used by:
- Manufacturers of pressure regulators, change‑over devices, adaptors and integrated safety devices to design and certify compliant products.
- Test laboratories and certification bodies performing type testing and conformity assessment.
- System designers and installers in domestic, leisure (caravans, boats) and small commercial LPG systems to select compliant components.
- Regulators and procurement teams specifying safe, standardized gas pressure control equipment for supply and safety.
- Maritime and caravan equipment suppliers applying the annex requirements for freshwater and seawater use.
Related standards
- EN 15202 (cylinder valve connections) - referenced for connection definitions.
- National installation regulations - installation rules must follow member-country legislation.
