Overview

The draft European Standard prEN 13856:2024, developed by CEN/TC 286, specifies the minimum requirements for the content of user manuals for automotive LPG (liquefied petroleum gas) propulsion systems fitted in road vehicles. This standard updates and supersedes the earlier EN 13856:2002, aiming to ensure that end-users receive clear, comprehensive, and safety-focused information necessary for the proper operation, maintenance, and troubleshooting of LPG systems.

This standard covers crucial topics such as technical specifications, safety instructions, operational procedures, maintenance guidelines, and defect handling. It is intended for manufacturers, installers, and service providers involved with automotive LPG equipment and accessories, but explicitly excludes forklift trucks and other industrial machinery.

Key Topics

1. Technical Specifications
The user manual must provide:

• Detailed descriptions of the LPG system and its main components
• Information about the type of LPG fuel used
• Guidelines on system running-in and tuning requirements

2. Safety Instructions
Essential safety information includes:

• Correct usage of the LPG system
• Potential risks and dangers of misuse
• Procedures to follow in case of gas leaks
• Effects of environmental factors like humidity and temperature
• Maximum container filling level, capped at 80% volume to ensure safety
• Relevant national regulations on parking, maintenance, and system re-approval

3. Operation Procedures
Users must be guided on:

• Proper filling of the LPG container with emphasis on the 80% filling limit
• Switch-over procedures between LPG and conventional fuel, especially if a manual switch is present
• How to open and close manual valves for safety or in response to leaks
• Interpreting the LPG level indicator, including its location and reading instructions

4. Maintenance Guidance
The manual should specify:

• Maintenance frequency and types of maintenance necessary for safety and system longevity
• Requirement that maintenance is performed by competent personnel, for example as per EN 16652-2
• Special procedures when vehicles undergo repainting or exposure to hot painting/drying environments

5. Defect Management
Instructions are required on:

• Actions to take when defects are detected
• Repair guidance for faulty system components
• Use of any diagnostic systems included in the LPG installation

Applications

The prEN 13856:2024 standard supports manufacturers, service workshops, and vehicle operators by providing a uniform framework for the documentation essential to safe and efficient use of automotive LPG systems. The user manuals developed according to this standard can be used for:

• Enhancing end-user safety by clear communication of risks and precautions
• Supporting regulatory compliance through harmonized documentation
• Facilitating proper operation and maintenance, thereby extending the life of LPG equipment
• Providing a basis for training material for technicians and service personnel
• Enabling better emergency response actions in case of leaks or malfunctions

This standard is critical for Europe’s push towards environmentally friendly automotive fuels by ensuring that LPG systems are operated and maintained responsibly and safely.

Related Standards

prEN 13856:2024 should be read in conjunction with these relevant CEN documents:

• CEN/TS 16765 – Environmental considerations for LPG equipment design, manufacture, packaging, use, and disposal
• prEN 12805 – Standards for automotive LPG containers
• EN 12806 – Standards for automotive LPG components other than containers
• EN 16652-2 – Competence and training requirements for personnel in LPG vehicle workshops

Together, these linked standards help establish a comprehensive framework for LPG system quality, safety, and environmental compliance.
