This European Standard describes a test method for determining the intrinsic characteristics of sound diffraction of added devices installed on the top of railway noise barriers. The test method prescribes measurements of the sound pressure level at several reference points near the top edge of a noise barrier with and without the added device installed on its top. The intrinsic effectiveness of the added device is calculated as the difference between the measured values with and without the added devices, correcting for any change in height. In other words, the method described here gives the acoustic benefit of changing the shape and materials of the top edge over a simple barrier of the same height. This is an intrinsic characteristic of the added device, provided that the source and receiver positions are standardized. In practice, when the added device is placed over an existing barrier, it raises the height and this provides additional screening, depending on the source and receiver positions, not considered in this European Standard.
The test method is intended for the following applications:
-   preliminary qualification, outdoors or indoors, of added devices to be installed on noise barriers;
-   determination of sound diffraction index difference of added devices in actual use;
-   comparison of design specifications of an added device with actual performance data after the completion of the construction work;
-   verification of the long term performance of added devices (with a repeated application of the method);
-   interactive design process of new products, including the formulation of installation manuals.
The test method can be applied both in situ and on samples purposely built to be tested using the method described here.
Results are expressed as a function of frequency, in one-third octave bands between 100 Hz and 5 kHz. If it is not possible to get valid measurements results over the whole frequency range indicated, the results shall be given in the restricted frequency range and the reasons for the restriction(s) shall be clearly reported. A single-number rating is calculated from frequency data.
For indoor measurements, see Annex A.

This European Standard specifies principles and requirements for measuring multiple and articulated freight wagons. This ensures that the measuring processes are applied in accordance with uniform criteria. It applies to new and modified multiple and articulated freight wagons.
Provisions going beyond the scope of these requirements are generally agreed between the contracting parties involved.

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.

The calculation method described in this European standard has been developed for noise barriers having a post-and-panel structure with piled foundations. It can also be used where cladding is attached to a rigid structure. For structures with piled foundations, an empirical formula for determination of the natural frequency is given in Annex A. Annex B contains an example of application of the calculation method for determination of internal forces and moments acting on a mid-post. The design of noise barriers (e.g. to fatigue resistance) is not part of this standard.

1.1   General
This European Standard specifies the technical requirements to minimise the specific railway hazards of self propelled demountable machines - henceforward referred to as machines - and associated equipment, which can arise during the commissioning, the operation and the maintenance of these machines when carried out in accordance with the specification given by the manufacturer or his authorised representative. These machines are not designed or intended to operate signalling and control systems and are only designed and intended to work and run under special operating conditions specifically designated by the infrastructure manager. Other machines are dealt with in other European Standards; see Annex D.
This part of EN 15955 deals with the technical railway requirements; Part 2 deals with the requirements for the machine to be declared conformant by the manufacturer, except in the case of machines classified in Annex 4 of the Machinery Directive (2006/42/EC) which requires conformity check in conjunction with a notified body.
These demountable machines are not intended to be vehicles as defined in the Interoperability Directive and are not permitted to run on the railway lines open to normal traffic. If this is required, they will need to be authorised or placed into service as set out in the Interoperability Directive 2008/57/EC.
Additional requirements can apply for running on infrastructures with narrow gauge or broad gauge lines, lines of tramways, railways utilising other than adhesion between the rail and rail wheels and underground infrastructures.
This European Standard is also applicable to machines and associated equipment that in working configuration are partly supported on the ballast or the formation.
This European Standard does not apply to the following:
-   requirements for quality of the work or performance of the machine;
-   specific requirements established by the railway infrastructure operator for the use of machines, which will be the subject of negotiation between the manufacturer and the purchaser;
-   separate machines temporarily mounted on demountable machines and associated equipment.
This European Standard does not establish the additional requirements for the following:
-   operation subject to special rules, e.g. potentially explosive atmospheres;
-   hazards due to natural causes, e.g. earthquake, lightning, flooding;
-   working methods;
-   operation in severe working conditions requiring special measures, e.g. work in tunnels or in cuttings, extreme environmental conditions (below – 20 °C or above + 40 °C), corrosive environment, contaminating environments, strong magnetic fields;
-   hazards due to errors in software;
-   hazards occurring when used to handle suspended loads which may swing freely.
The intended use of these machines may have operational parameters specified by each infrastructure manager, e.g. the maximum speed allowed for these machines is likely to be limited by the infrastructure manager; compliance with the clauses of this standard does not confer permission for machines to travel at this speed. These machines will not be allowed on a track open to normal railway traffic.

-   to define limits of weld rectification by the supplier;
-   special requirements for pre-hardened crossings.
Geometrical aspects, as machining tolerances and inspection of finished crossings are covered in EN 13232-6 and EN 13232-7 and therefore not in this European Standard.
This European Standard specifies the minimum requirements for cast manganese crossing components. Special applications (for instance tram systems) can require different demands in certain paragraphs and need to be agreed between customer and supplier.

This European Standard specifies the definitions of the terms used in the EN 13146 series and in the EN 13481 series.
