Railway applications - Track - Concrete sleepers and bearers - Part 1: General requirements
This part of EN 13230 defines technical criteria and control procedures which have to be satisfied by the constituent materials and the finished concrete sleepers and bearers, i.e.: precast concrete sleepers, bearers for switches and crossings, and special elements for railway tracks.
The main requirement of concrete sleepers and bearers is the transmission of vertical, lateral and longitudinal loads from the rails to the ballast or other support. In use they are also exposed to frost damage and to moisture, which can result in detrimental chemical reactions within the sleeper.
In this standard mechanical tests are defined which provide assurance of the capability of sleepers or bearers to resist repetitive loading and provide sufficient durability. In addition controls are placed on manufacturing processes and tests to ensure that the concrete will not suffer degradation in service through chemical reaction and frost damage.
Bahnanwendungen - Oberbau - Gleis- und Weichenschwellen aus Beton - Teil 1: Allgemeine Anforderungen
Dieser Teil der Normenreihe EN 13230 legt die technischen Kriterien und Kontrollverfahren fest, denen die Baustoffe und Fertigerzeugnisse, d. h. aus Beton gefertigte Gleis- und Weichenschwellen, bewehrte Zweiblockschwellen, Schwellen für Weichen und Kreuzungen und spezielle Schwellen (Sonderformen) für Eisenbahngleise, genügen müssen.
Die Hauptaufgabe von Gleis- und Weichenschwellen aus Beton ist die Übertragung vertikaler, horizontaler und longitudinaler Lasten von den Schienen auf den Schotter oder eine andere Tragschicht. Während des Einsatzes sind sie sowohl Frost als auch Feuchtigkeit, die zu schädlichen chemischen Reaktionen innerhalb der Gleisschwellen führen kann, ausgesetzt.
In dieser Norm werden mechanische Prüfungen festgelegt, die die Gebrauchstauglichkeit und Dauer-haftigkeit von Gleis- und Weichenschwellen aus Beton gegenüber wiederholten Belastungen sicherstellen. Zusätzliche Kontrollen sind für die Herstellungsverfahren erforderlich und Prüfungen sind durchzuführen, um sicherzustellen, dass der Beton im Laufe der Nutzung keine Festigkeitsverluste durch chemische Reaktion und Frostschäden erfährt.
Applications ferroviaires - Voie - Traverses et supports en béton - Partie 1 : Prescriptions générales
La présente partie de la série EN 13230 traite des prescriptions générales relatives aux traverses et supports en béton et est utilisée conjointement avec les parties suivantes :
— Partie 2 : Traverses monoblocs précontraintes
— Partie 3 : Traverses biblocs en béton armé
— Partie 4 : Supports précontraints pour appareil de voie
— Partie 5 : Éléments spéciaux
— Partie 6 : Conception
Les traverses et les supports en béton, du fait de la sécurité, sont des constituants spécifiques du domaine ferroviaire. Ils ne sont couverts par aucune autre norme.
En tant que constituants de sécurité un accord est nécessaire entre client et fournisseur pour la mise en œuvre d’un système qualité en production.
Cette position a toujours été mise en exergue par les résolutions prises au CEN/TC 256/SC 1 « Applications ferroviaires – Infrastructure » et des informations détaillées figurent dans l’Annexe ZA.
Železniške naprave - Zgornji ustroj proge - Betonski pragi in kretniški betonski pragi - 1. del: Splošne zahteve
Ta del standarda EN 13230 določa tehnične kriterije in kontrolne postopke, ki jih morajo izpolnjevati sestavni materiali ter končni betonski pragi in kretniški betonski pragi, npr. montažni betonski pragi, kretniški betonski pragi za kretnice in križišča ter posebne oblike pragov za železniške proge.
Glavna zahteva za betonske prage in kretniške betonske prage je prenos navpičnih, stranskih in vzdolžnih obremenitev s tračnic na gramozno gredo ali drugo podporo. Med uporabo so izpostavljeni tudi poškodbam zaradi zmrzovanja in vlage, kar lahko povzroči škodljive kemične reakcije v betonskem pragu.
V tem standardu so določeni mehanski preskusi, s katerimi se lahko zagotovita odpornost betonskih pragov in kretniških betonskih pragov proti ponavljajočim se obremenitvam ter zadostna vzdržljivost. Prav tako se izvaja kontrola proizvodnih postopkov in preskusov, s čimer se zagotovi, da ne pride do uničenja betona zaradi kemičnih reakcij in poškodb zaradi zmrzovanja.

Introduction
This part of the EN 13230 series covers the general requirements for concrete sleepers and bearers and
is used in conjunction with the following parts:
— Part 2: Prestressed monoblock sleepers;
— Part 3: Twin-block reinforced sleepers;
— Part 4: Prestressed bearers for switches and crossings;
— Part 5: Special elements;
— Part 6: Design.
Concrete sleepers and bearers are safety critical components for railway applications. They are not
covered by any other standards.
As safety critical components, an agreement is needed between purchaser and supplier to operate a
factory Quality System.
This position about safety critical relevance has always been highlighted by decisions from
CEN/TC 256/SC 1 “Railway applications / Infrastructure” and Annex ZA provides detailed information.

1 Scope
This part of the EN 13230 series defines technical criteria and control procedures which need to be
satisfied by the constituent materials and the finished concrete sleepers and bearers, i.e.: precast
concrete sleepers, twin-block reinforced sleepers, bearers for switches and crossings, and special
elements for railway tracks.
The main requirement of concrete sleepers and bearers is the transmission of vertical, lateral and
longitudinal loads from the rails to the ballast or other support. In use, they are also exposed to frost
damage and to moisture, which can result in detrimental chemical reactions within the sleeper.
In this standard mechanical tests are defined which provide assurance of the capability of sleepers or
bearers to resist repetitive loading and provide sufficient durability. In addition, controls are placed on
manufacturing processes and tests to ensure that the concrete will not suffer degradation in service
through chemical reaction and frost damage.

4 Common characteristics
4.1 General
The track is an assembly of transverse sleepers or bearers secured to the rails by means of a fastening
system and supported by ballast or other support. It is characterized by the gauge of the track, the rail
profile, the inclination of the rails and the spacing of the concrete sleepers and bearers.
4.2 Loading
4.2.1 Loads
The track is subjected to repeated loads in three different directions, generally applied simultaneously:
a) vertical loads from axle load and service conditions;
b) transverse loads from guiding forces;
c) longitudinal loads from acceleration and braking, thermal stresses in continuous welded rail, etc.
Under all loading conditions, the track has to retain its geometry including gauge, top level and
alignment.
The characteristic load is calculated by applying a dynamic coefficient to the static wheel load.
The dynamic coefficient takes into account the normal dynamic effects of wheel and track irregularities.
Loads and the corresponding bending moments are the responsibility of the purchaser.
4.2.2 Load distribution
The assembled rail, fastening system and concrete sleepers and bearers on ballast or other support
shall be considered as a beam on a continuous resilient support.
10
---------------------- Page: 12 ----------------------
SIST EN 13230-1:2016
EN 13230-1:2016 (E)
The moment of inertia of the rail profile, the spacing of the concrete sleepers and bearers and the
elasticity of the whole assembly on its support, have an influence on the longitudinal distribution of the
vertical loads applied on the rail. As a result, the rail seat load applied on the concrete element is only a
proportion of the wheel load.
4.3 Characteristic bending moments
The characteristic bending moments are defined in kNm by the concrete sleeper and bearer design
criteria and are used to calculate test loads.
Characteristic bending moments are seldom reached in the life time of the sleeper.
See prEN 13230-6:2015, 4.2.
4.4 Data to be supplied
4.4.1 General
The purchaser can require all the data from the supplier before the design approval tests.
4.4.2 Data to be supplied by the purchaser
The purchaser shall specify the following data:
a) all characteristic bending moments (M ; M ; M , ) and when required (M );

b) impact coefficients (k ) and (k ), and when required (k ) and (k ) as defined in
