Introduction
This document calls for the use of substances and procedures that can be injurious to health if adequate
precautions are not taken. It refers only to technical suitability and does not absolve the user from legal
obligations relating to health and safety at any stage.
It has been assumed in the drafting of this document that the execution of its provisions is entrusted to
appropriately qualified and experienced people.
Protection of the environment is a key political issue in Europe and elsewhere. For CEN/TC 286 this is
covered in CEN/TS 16765 and this Technical Specification should be read in conjunction with this
standard. The Technical Specification provides guidance on the environmental aspects to be considered
regarding equipment and accessories produced for the LPG industry and the following is addressed:

visible and legible under all foreseeable operating and ageing conditions.
— Markings required to be “permanent” shall be such that they can only be removed with the use of
special tools and can be done, for example by hard metal stamping, engraving, casting, embossing,
encapsulation or other similar methods.
— Markings required to be “durable” shall be such that they remain visible and legible for the relevant
period of time and can be done, for example by printing, external labelling, stencilling, use of valve
hand-wheel insert or other similar methods.
