Foreword

This document (CEN/TR 15545:2006) has been prepared by Technical Committee CEN/TC 203 “Cast iron

pipes, fittings and their accessories”, the secretariat of which is held by AFNOR.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.

EN 545 deals with components of piping systems for water - pipes, fittings and joints – which, together, form

the part of a water network. Each of these components can be manufactured by a different supplier, which is

often the reality; the performances and the tests required by EN 545, although perfectly comprehensive, are

not always formulated with enough accuracy to be easily used in every real situation occurring the market.

In regard to quality assurance, the attestations and certifications of conformity to the standards available on

the markets:
 attestation of compliance to the performance tests;
 certification of conformity of the products of a batch;
 certification of conformity to EN ISO 9001 of the supplier;
 national quality or conformity marks;
 third party certification of conformity of products to a standard,

 self-declaration of conformity to a standard by the supplier for products that he sells,

have different meanings for the customer, who generally needs all products to be fully in compliance with this

standard.

1 Scope

EN 545 specifies the requirements and associated test methods applicable to ductile iron pipes, fittings,

accessories and their joints for the construction of pipelines:
 to convey water (e.g. potable water);
 with or without pressure;
 to be installed below or above ground.

In respect to potential adverse effects on the quality of water intended for human consumption, caused by the

product covered by this standard:

 this standard provides no information as to whether the product may be used without restriction in any of

the member states of the EU or EFTA;

 it should be noted that, while awaiting the adoption of verifiable European criteria, existing national

regulations concerning the use and/or the characteristics of this product remain in force.

This technical report:
— explains in more detail the process of testing for the performance tests;

— explains in more detail the definitions of the different types/levels of attestation to enable customers to

ensure their requirements are fulfilled;

— explains in more detail the ways of certification of conformity with EN 545 for a reliable evaluation of the

performance of the products.

In order to make the use of this Technical Report easier, the clauses of this document refer to the

corresponding clause numbers in EN 545.
4.1.4 Materials in contact with water intended for human consumption

A comprehensive potability regulation concerning components of pipes systems means:

 regulatory obligation ( i.e.: decree, law….);
 technical specifications;
 tests methods to verify the compliance with the technical specifications;
 directory of approved laboratories able to carry out these tests.

On October the 1 2005, there was a national regulation in the following countries: Austria, France, Germany,

Italy, Netherlands, Switzerland and United Kingdom.
In all cases, the national regulations remain in force and must be followed.
6.6 Zinc mass

EN 545 states that a rectangular token of known weight per unit area shall be attached longitudinally along the

axis of the pipe before passing through the coating equipment. After zinc coating and trimming, the size of the

---------------------- Page: 6 ----------------------
SIST-TP CEN/TR 15545:2007
CEN/TR 15545:2006 (E)

token shall be 500 mm x 50 mm. It shall be weighed on a scale having an error limit of ± 0,01g. The mean

mass is then determined in accordance with the remainder of clause 6.6.

As this test can only be carried out in the factory, conformity certification using this test method can only be

acquired and granted in the factory during the manufacturing process and not on a batch of finished products.

7 Performance test methods
7.1 Compressive strength of the cement mortar lining

This test should be carried out using the actual constituents used in the manufacture of the cement mortar for

the pipes. As such the sand, cement and water should be sampled from the dispensing/holding facilities in the

factory. Similarly, the sand/cement/water ratios should be identical to those used in the manufacturing process

(in the case of the sprayed mortar process, these ratios are identical to the ratio in the mortar mixer, whereas

for the centrifugal process, these ratios are those found in the compacted lining after centrifugal spinning).

Third party accreditation can thus only be granted once these strict conditions have been established and it is

for this reason that it is recommended that these tests be only carried out in the factory.

7.2 Leak tightness of flexible joints to positive internal pressure

The test shall be carried out in accordance with clause 7.2 of EN 545 on an assembled joint comprising two

pipe sections, each at least 1 m long. It shall be carried out separately for other components such as fittings if

their socket differs from that of the spun pipes. For such a test a flange-socket fitting (see 8.3.1 of EN 545)

shall be bolted to a flanged pipe of sufficient length to satisfy the requirements of clause 7.2. Tests shall be

carried out on both unrestrained and restrained joints as necessary.

 Short and long term characteristics of the rubber for the gaskets shall be shown to be in compliance with

EN 681-1.

 Relevant designs of socket and gasket throughout all possible tolerance combinations shall:

 ensure leak tightness at minimum compression under shear and/or angular deflection;

 ensure both leak tightness and satisfactory anchorage under shear and/or angular deflection.

 The short and long term characteristics of the rubber for the gaskets shall be shown to be in compliance

with EN 681-1.

 Using an established gasket, the relevant designs of sockets/spigots shall be shown to be compatible

throughout all possible tolerance combinations (see clause 7.2.3) and shall:

 ensure leak tightness at minimum compression under shear and/or angular deflection;

 ensure both leak tightness and satisfactory anchorage (restrained joint) under shear and/or angular

deflection – especially important where different suppliers of pipes/fittings and gaskets are involved.

The following joint parameters are considered vital to the performance of a joint and shall be checked to be in

accordance with the relevant specifications:
 wall thickness;
 external diameter of spigot;
 socket internal functional diameters;
 depth of socket;
 gasket diameters and thicknesses.
