1 Scope
This document is applicable to resilient elements for floating slab system (REFS) – elements used in floating slab and defines the test procedures and their acceptance
criteria.
The document covers not only those parameters related to the effectiveness of a track
structure in mitigating vibrations, that is, to reduce the emission of vibrations
and structure-borne noise, but also the parameters that are needed for the static
analysis and for the verification of track safety.
Floating slab track systems in the form of track base plates and track troughs are
individual solutions in which there is considerable variation in the engineering design
and the types of resilient elements used. For this reason, a floating slab track system
is always an individual engineering solution and therefore, it is not possible to
define all specific conditions for the resilient elements in this document.
The most typical types of resilient elements are:
This document provides particular information in the following areas:
-
— test methods, test arrangements and acceptance criteria;
-
— data supplied by the purchaser and by the supplier;
-
— definition of general process of design approval tests;
-
— definition of routine tests.
This document defines the specific test procedures for REFS:
This document also sets out procedures for testing fitness for purpose and provides
information on quality monitoring as part of quality assurance procedures. This document
does not, however, contain requirements pertaining to the functions of Resilient Element for Floating Slab system. It is the responsibility of the purchaser to define these requirements and to choose the optional tests.
This document is not applicable for fastening system and for booted concrete block
and sleeper completed with boots covered by EN 13481‑5.
