Introduction
The System Standard, of which this is Part 7, specifies the requirements for a piping system and its components
made from polyethylene (PE) and is intended to be used for the supply of gaseous fuels.
Requirements and test methods for material and components of the piping system are specified in EN 1555-1,
EN 1555-2, EN 1555-3 and EN 1555-4. Characteristics for fitness for purpose are covered in EN 1555-5.
[1]
Recommended practice for installation is given in EN 12007-2 prepared by CEN/TC 234.
This Part of EN 1555 gives guidance to procedures and requirements for the assessment of conformity of
materials, components, joints and is intended to be used by manufacturers, inspection bodies, testing laboratories
and certification bodies.
1 Scope
This Part of EN 1555 gives guidance for assessment of conformity to be included in the manufacturer's quality plan
as part of the quality system.
This Part of EN 1555 includes:
a) requirements for materials, components and joints given in the applicable Parts of EN 1555;
b) requirements for the manufacturer's quality system;
[2]
NOTE 1 It is recommended that the quality system conforms to EN ISO 9001 .
c) definitions and procedures to be applied if third party certification is involved.
[3]
NOTE 2 If third party certification is involved, it is recommended that the certification body is accredited to EN 45011 or
[4]
EN 45012 , as applicable.
In conjunction with the other Parts of EN 1555 it is applicable to PE pipes, fittings, and valves, their joints and to
joints with components of other materials intended to be used under the following conditions:
1)
a) a maximum operating pressure, MOP, up to and including 10 bar ;
b) an operating temperature of 20 °C as reference temperature.
NOTE 3 For other operating temperatures, derating coefficients can be used, see EN 1555-5.
[5] [6] [7]
For mechanical fittings conforming to ISO 10838-1 , ISO 10838-2 or ISO 10838-3 , as applicable, guidance
for assessment of conformity is not given in this part of EN 1555. When requested, a quality plan based on the
[5] [6] [7]
tests mentioned in ISO 10838-1 , ISO 10838-2 or ISO 10838-3 , as applicable, should be set up in
agreement between user and manufacturer.
EN 1555 covers a range of maximum operating pressures and gives requirements concerning colours and
additives.
NOTE 4 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into
account their particular requirements and any relevant national regulations and installation practices or codes.
