Foreword

This document (CEN/TR 16017:2010) has been prepared by Technical Committee CEN/TC 203 “Cast iron

pipes, fittings and their joints”, 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 598 deals with components of piping systems for sewerage – pipes, fittings, accessories and joints –

which together, form the part of a sewerage 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 598, although

perfectly comprehensive, are not always formulated with enough accuracy to be easily used in every real

situation occurring in 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.

In addition EN 598 is now a harmonized standard prepared under the Mandate M/131 “Pipes, tanks and

ancillaries not in contact with water intended for human consumption” and as such products should be CE

marked.

Scope

EN 598 specifies the requirements and associated test methods applicable to ductile iron pipes, fittings,

accessories and their joints for the construction of drains and sewers outside buildings:

 operating without pressure (gravity sewerage), or with positive or negative pressure;

 to be installed below or above ground;

 to convey surface water, domestic waste water and certain types of industrial effluents, either in separate

systems or in combined systems.
This technical report:
 explains in more detail the process of testing for the performance tests;
 explains in more detail the benefits of high alumina cement lining;

 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 598 for a reliable evaluation of the

performance of products;

 explains in more detail CE marking and its relevance i.e. the CE mark is not a mark of conformity with a

standard but only a self-declaration concerning the CPD essential requirements.

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

corresponding clause numbers in EN 598.
4.1.3.1 Gasket materials

Gaskets for sewerage application are manufactured from rubber in compliance with EN 681-1 type WC or

WG. This ensures that the gasket is unaffected by any hydro-carbons discharged from the sewerage

environment. In addition, the designated rubber offers the required resistance to benzene derivatives, such as

those contained in oily waste.
4.4.3 Internal lining of high alumina cement mortar

Ductile iron pipes for sewerage applications are internally lined with high alumina cement mortar as standard

thus protecting the internal surface of the ductile iron pipes against corrosion and tuberculation. High alumina

cement lining provides a high resistance to both chemical and septic (biogenic corrosion of cement mortar

lining) attack found in the vast majority of sewers. Similarly, it offers excellent resistance to abrasion brought

about by the impact of solid particles contained in the effluent. The performance of both of these is ensured by

the tests detailed in EN 598 sub-clauses 5.8 Chemical resistance and 5.9 Abrasion resistance.

Linings with a high compressive strength (min 50 MPa - see 5.10), also exhibit high density, good adhesion

and low porosity: all of which parameters are conducive to a long working life.

4.4.4 Coating of joint areas

A possible area of weakness in the corrosion protection in sewer systems could be where the conveyed

sewage comes into contact with the “external coating” of the pipe i.e. internal surface of the socket and the

external surface of the spigot in the joint area. This is not the case with EN 598 pipes where the joint areas of

ductile iron pipes (internal surface of the socket and external surface of the spigot) for sewerage applications

are coated with a synthetic resin (epoxy, polyurethane etc.). These coatings conform without failure to the

stringent test for chemical resistance to effluents of EN 598 sub-clause 5.8. This ensures that the surface in

contact with the effluent does not crack, blister or disbond for the life of the sewer, preventing the onset of

biogenic corrosion.
5.6 Flanged joints

The test for flanged joints shall be carried out in accordance with EN 545 on an assembly comprising two

pipes or fittings with identical flanges together with a relevant gasket and bolts recommended by the

manufacturer. It is important that rubber gaskets shall be shown to have the short and long term properties as

defined in EN 681-1, in particular the hardness (IRHD) is within specification. Similarly, it is important that the

manufacturer’s jointing instructions are followed for each particular gasket/material as regards torque values

and lubrication for the bolts. The sealing of flange joints depends on many factors and the manufacturer

should have written specifications for:
 flange joint faces – surface finish, flatness, permissible irregularities;
 flange jointing materials – bolt lengths/grades, recommended gasket materials;
 jointing instructions – bolt torques, lubrication, bolt tightening sequence.
5.7 Pipes with screwed or welded flanges

The test for pipes with screwed or welded flanges shall be carried out in accordance with EN 545 on an

assembly comprising two pipes with identical flanges together with a relevant gasket and bolts. This test is

primarily a strength test for the weld/screwed connection and as such is very demanding.

Because this is a specialist test on pipes that can only be welded/screwed by the manufacturer, the test can

usually only be carried out and third party accredited in the factory.
