Introduction

This document specifies requirements for the installation of equipment for the use of Liquefied

Petroleum Gas (LPG) in the propulsion systems of small watercraft.

This document calls for the use of substances and procedures that can be injurious to health if adequate

precautions are not taken.

Protection of the environment is a key political issue in Europe and elsewhere, for TC 286 this is covered

in CEN/TS 16765 [2] LPG equipment and accessories - Environmental considerations for CEN/TC 286

standards, and this Technical Specification should be read in conjunction with this standard.

It has been assumed in the drafting of this document that the execution of its provisions is entrusted to

appropriately qualified and experienced persons.
This document is based on EN 12979 [3].
