TS 12664-1/T1

TS 12664-1/T1 addresses the general rules for places that convert road vehicle fuel systems for use with liquefied petroleum gas (LPG). Rather than setting out a specific conversion procedure, it focuses on the overall framework expected from these service locations: operating practice, physical characteristics, technical equipment, and the qualifications of the personnel involved.

Why the technical setting matters in LPG conversion services

LPG conversion is a technical modification activity that may involve adapting or supplementing a vehicle’s original fuel system. In general technical terms, this means the service environment, the available tools and equipment, the installation conditions, and the competence of the staff all affect the consistency of the work. For this type of service, the layout of the workplace and the capability of the personnel are important because they support orderly operations and help reduce the likelihood of problems after conversion.

General areas covered by the standard

• General operating rules for the service provider
• Physical characteristics and workplace arrangement
• Technical equipment and tooling
• Personnel characteristics and competence

The standard serves as a baseline reference for service places carrying out LPG conversion work on road vehicles. Because fuel system conversion brings together mechanical work, gas-system considerations, and vehicle-related technical know-how, the subject of the standard extends beyond equipment alone to include how the service organization is structured and how the work is staffed.
