Overview

EN 1949:2011/FprA1:2012 (CEN) is a draft amendment to EN 1949:2011 that specifies safety and installation requirements for liquefied petroleum gas (LPG) systems used for habitation in leisure accommodation vehicles (caravans, motorhomes) and for accommodation purposes in other vehicles. The amendment clarifies definitions, updates component and mounting requirements, and adds safety and labeling provisions for LPG tanks, regulators, change‑over devices and ventilation. Keywords: EN 1949:2011/FprA1:2012, LPG installation, leisure accommodation vehicles, caravan gas systems, campsite equipment.

Key Topics and Requirements

• Definitions updated: Clear definitions for LPG, regulator, pressure regulation system and change‑over device to align terminology across installations.
• Pressure regulation and flow: Road‑vehicle pressure regulation systems must have a fixed working pressure of 30 mbar and comply with EN 12864 (Annex D or M) with a maximum flow rate of 1.5 kg/h. Automatic change‑over devices must comply with EN 13786.
• Tank fittings and accessories: LPG tanks must meet Pressure Equipment Directive and UN/ECE Regulation No. 67‑01 (Part I). Mandatory accessories include 80% filling stop valve, level indicator, pressure relief (discharge) valve, excess flow valve, and a manually operated service valve.
• Mounting and mounting position: Tanks and fittings must be mounted so only gaseous phase is withdrawn; correct tank orientation must be indicated; components in contact with liquid LPG follow UN/ECE requirements.
• Refilling safety: Service valve position and/or additional valves or automatic isolation for refilling; filling unit must be at least 500 mm from ventilators, windows or flue outlets.
• Ventilation and labels: Low‑level ventilation specifics and requirement for cylinder compartment labeling (pictogram + “read instructions”). A warning label (Figure 12) to turn off all LPG appliances before refilling is required at filling points.
• Appliance connections: Flexible hoses for movable cooking appliances allowed under conditions (protected, accessible, max length 750 mm, shut‑off valve immediately before hose).
• Flue clearances: Flue terminals for appliances >30 g/h LPG must not be within 300 mm of a living‑space ventilator or opening window; automatic shut‑off required when vertical flue terminal is below an openable window.

Applications

• Installation, design and commissioning of LPG systems in caravans, motorhomes, campervans and other vehicle accommodation.
• Safety checks, conformity assessment and refurbishment of onboard LPG tanks, regulators and piping.
• Guidance for manufacturers, installers, maintenance engineers, vehicle certifiers and safety inspectors working on LPG systems for leisure vehicles and camping equipment.

Related Standards

• EN 12864 (pressure regulators)
• EN 13786 (change‑over devices)
• UN/ECE Regulation No. 67‑01 (LPG tanks, fittings)
• EN 12979 (mechanical mounting/acceleration forces)

This standard is essential for ensuring safe, compliant LPG installations in leisure accommodation vehicles and related applications.
