Foreword
This document (prEN 12514-4:2009) has been prepared by Technical Committee CEN/TC 47 “Atomizing oil
burners and their components – Function – Safety – Testing”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 12514-1:2000, EN 12514-2:2000.
According to editions 2000 the following fundamental changes are given:
 standards new structured;
 new parts for supply systems included;
 technical requirements revised;
 number of cycles for the fitness-for-use test added;
 requirements for flood proof parts included;
 selections of materials;
 marking, packing and instructions revised.
This standard consists of 4 Parts:
Parts for supply systems for consuming units with liquid fuels
Part 1: Safety requirements and tests — Terminology, general requirements
Part 2: Safety requirements and tests — Feed pumps, control and safety devices, service vessels
Part 3: Safety requirements and tests — Valves and meters
Part 4: Safety requirements and tests — Pipings and parts within pipelines
1 Scope
This European Standard applies to the following parts of supply systems for the automatic liquid fuel supply of
consuming units from one or more tanks:
a) pipes;
b) fasteners;
c) pipeline connections;
d) parts within pipes;
Combinations of single parts are acceptable.
