Introduction

This document calls for the use of substances and procedures that may be injurious to health and/or the

environment if adequate precautions are not taken. It refers only to technical suitability and does not

absolve the user from legal obligations at any stage.

This document is intended for users who take on the responsibility for the manufacturing of composite

pipe.

Protection of the environment is a key political issue in Europe and elsewhere. For CEN/TC 286 this is

covered in CEN/TS 16765 [1] and this Technical Specification should be read in conjunction with this

document. This document provides guidance on the environmental aspects to be considered regarding

equipment and accessories produced for the LPG industry and the following is addressed:

a) design;
b) manufacture;
c) packaging;
d) use and operation; and
e) disposal.

It is recommended that manufacturers develop an environmental management policy. For guidance see

EN ISO 14004 [2]. It has been assumed in the drafting of this document that the execution of its provisions

is entrusted to appropriately qualified and experienced people.
All pressures are gauge unless otherwise stated.

NOTE This document uses measurement of material properties, dimensions and pressures. All such

measurements are subject to a degree of uncertainty due to tolerances in measuring equipment, etc. It could be

beneficial to refer to the leaflet “measurement uncertainty leaflet (SP INFO 2000 27 uncertainty.pdf)” [9].

1 Scope

This document specifies requirements for the design, manufacture and testing of composite pipe for use

with LPG in liquid phase and vapour pressure phase.

This document is applicable to LPG composite pipe having a maximum allowable pressure of less than or

equal to 25 bar.

This document applies to pipe made from thermoplastics, which can include some degree of

reinforcement.

It does not apply to fibre reinforced thermosets, commonly referred to as glass fibre reinforced plastic

(GRP), nor rigid metals or corrugated metal pipe or hoses to EN ISO 10380 [6].

For the purpose of this document, composite pipe refers to the design requirements below:

a) Design 1: PE-based thick-walled pipe with multi-layer design without additional reinforcement than

the wall thickness of the PE;

b) Design 2: Nylon-based multi-layer design with a polyester or aramid braid for reinforcement.

NOTE For installation of composite pipework systems, see EN 16125.
