Railway infrastructure - Rail fastening systems - Part 3: Proof load test method for pull-out resistance (ISO 22074-3:2021)

This document specifies a test procedure to confirm that the force necessary to pull the anchorage of a rail fastening assembly out of the sleeper or other supporting element is greater than a prescribed value (i.e. it is a "proof load" test).
This test is for components of the fastening system which are:
a)   cast into concrete during the manufacture of sleepers or other supporting elements;
b)   glued into the cast or drilled holes in concrete; or
c)   screwed or otherwise attached to wood, polymeric composite or steel sleepers or other supporting elements.
This test is not applicable to embedded rails.

Infrastructure ferroviaire - Systèmes de fixation du rail - Partie 3: Méthode d'essai de charge d'épreuve pour la résistance à l'arrachement (ISO 22074-3:2021)

Ce document spécifie une procédure d'essai pour confirmer que la force nécessaire pour arracher l'ancrage d'un système de fixation de rail de la traverse ou d'un autre élément de support est supérieure à une valeur spécifiée (c'est-à-dire qu'il s'agit d'un essai de " charge de preuve ").
Cet essai concerne les composants des systèmes de fixation suivants:
a)    coulée dans le béton lors de la fabrication des traverses ou d'autres éléments de support;
b)    collés dans les trous coulés ou percés dans le béton; ou
c)    vissés ou autrement fixés à des traverses en bois, en composite polymère ou en acier ou à d'autres éléments de support.
Le présent essai ne s'applique pas aux rails enrobés.

Železniška infrastruktura - Sistemi za pritrjevanje tirnic - 3. del: Metoda preskušanja izvlečne odpornosti z določenim obremenjevanjem (ISO 22074-3:2021)

Ta dokument določa preskusni postopek, s katerim se potrdi, da je sila, potrebna za utrganje sidrišča pritrdilnega sestava za tirnice s praga ali drugega podpornega elementa, večja od predpisane vrednosti (tj. obremenitveni preskus).
Ta preskus se uporablja pri komponentah pritrdilnega sistema, ki so:
a) ulite v beton med izdelavo pragov ali drugih podpornih elementov;
b) zlepljene v vlite ali izvrtane luknje v betonu ali
c) privite ali kako drugače pritrjene na lesene, polimerno kompozitne ali jeklene pragove ali druge podporne elemente.
Ta preskus se ne uporablja za vgrajene tirnice.

Overview

EN ISO 22074-3:2024 - Railway infrastructure - Rail fastening systems - Part 3: Proof load test method for pull-out resistance (ISO 22074-3:2021) defines a laboratory test procedure to verify that the force required to pull a fastening insert or anchorage out of a sleeper or other supporting element exceeds a prescribed proof load. The standard applies to inserts that are cast into or glued into concrete, or screwed/attached into wood, polymeric composite or steel sleepers. Not applicable to embedded rails.

Key topics and technical requirements

• Test principle: Apply a vertical upward force to the anchored component until the prescribed proof load is reached, hold for 3 minutes, then remove the load. No damage that reduces system strength or durability should occur.
• Loading and equipment:
  • Actuator capable of at least 25% more than the specified proof load.
  • Force measurement equipment conforming to ISO 7500-1:2018, class 2.
  • Linkage must apply vertical force directly above the anchored part without introducing unrepresentative moments.
• Loading rate and geometry:
  • Load applied at a constant rate not exceeding 100 kN/min.
  • Distance from load line to inner edge of supports: (100 ± 5) mm (with guidance for exceptions).
  • If insert is inclined, load applied parallel to the insert axis; otherwise, normal to rail seat.
• Test specimens:
  • Use complete sleepers or representative support blocks (for ballastless track) without modification.
  • Concrete blocks shall have cube strength not greater than application concrete and no unexpected reinforcing close to the insert.
  • Minimum block depth: embedded length of insert plus 15 mm (or adequate depth to avoid bending failure).
• Inspection and reporting:
  • Inspect for any damage affecting integrity/durability.
  • Test report must reference ISO 22074-3:2021 and include lab details, specimen description and test results.

Applications and users

• Ensures anchorage reliability for rail fastening systems in:
  • Sleeper manufacturers (quality control of cast-in or glued inserts)
  • Railway infrastructure owners and contractors (acceptance testing)
  • Independent testing laboratories (type and production testing)
  • Designers and product developers (validation of insert designs)
• Practical benefits: reduces risk of fastening failure, supports procurement specifications, and verifies compliance with performance requirements in the ISO 22074 series.

• ISO 22074-1 - Vocabulary for rail fastening systems (referenced for terms).
• ISO 7500-1:2018 - Calibration and verification of force-measuring systems used in the test.
