TS 12664-1/T2

TS 12664-1/T2 is a standard concerned with the general rules for workplaces where road vehicle fuel systems are converted to use liquefied petroleum gas (LPG). The focus is not the vehicle as a finished product, but the setting in which the conversion service is carried out and the basic order expected of that workplace. In practical terms, it addresses the technical and organizational context of providing LPG conversion work in a controlled manner.

Technical context of LPG conversion workshops

LPG conversion normally involves coordinated work on fuel-system components such as the tank, pressure-regulating parts, piping, connectors and control elements. From a general engineering perspective, the workshop must support correct installation, leak-conscious assembly, orderly handling of electrical and mechanical connections, and a disciplined service environment suited to flammable fuel systems. Because LPG is stored under pressure and is combustible, the workplace arrangement and service workflow matter as much as the hardware itself.

How this document type should be understood

This is a general-rules standard, so it should be understood as describing the overall framework for places that perform LPG conversion work rather than a standalone product specification. Its withdrawn status indicates a historical regulatory role, but this record does not by itself provide detailed test methods, numerical limits or step-by-step procedures. For users, its value lies in identifying the workplace-focused nature of LPG conversion services and the need for organized, technically controlled working conditions.
