TS 12664-1

TS 12664-1 is a service standard concerned with the general rules for workshops that convert road vehicles so their propulsion systems can use LPG. Its focus is not the conversion hardware alone, but the organisation of the service place, the physical facilities it should provide, and the competence expected from personnel handling the work. In practical terms, it frames LPG conversion as a controlled technical service tied directly to the vehicle fuel system.

Facilities, equipment and personnel in LPG conversion services

Standards of this type bring together workshop layout, technical equipment and staff qualifications. LPG is stored under pressure and used in vehicles through dedicated components, so conversion work depends on compatible equipment, a suitable working environment and trained personnel. In general technical terms, a proper conversion must maintain system integrity across fuel supply routing, tank positioning, connection points and overall compatibility with the vehicle’s fuel system.

What this TSE document covers

The standard covers the operating rules of places that convert the fuel systems of road vehicles for LPG use, together with their physical characteristics and technical equipment. It also includes general rules on personnel characteristics. The referenced standards and regulatory links show that this service area is treated not only as workshop organisation, but also as a subject touching vehicle equipment and consumer service practice. This record is a withdrawn TSE standard, so it should be understood as a historical technical reference rather than an active edition.
