This document specifies the laboratory method for measuring the airborne sound insulation performance of railway noise barriers in reverberant conditions. It covers the assessment of the intrinsic performance of noise barriers and related devices acting on airborne sound propagation that can reasonably be assembled inside the testing facility described in EN ISO 10140 2 and EN ISO 10140 4.
This method is not intended for the determination of the intrinsic characteristics of airborne sound insulation of noise barriers to be installed on railway in non-reverberant conditions.
All noise reducing devices different from noise barriers and related devices acting on airborne sound propagation, e.g. devices for attenuation of ground borne vibration and on board devices, are out of the scope of this document.

This European Standard specifies the laboratory method for measuring the sound absorption performance of railway noise barriers and related devices acting on airborne sound propagation in reverberant conditions. It covers the assessment of the intrinsic sound absorption performance of devices that can reasonably be assembled inside the testing facility described in EN ISO 354.
This method is not intended for the determination of the intrinsic characteristics of sound absorption of noise barriers and related devices acting on airborne sound propagation to be installed on railways in non-reverberant conditions.
The test method in EN ISO 354 referred to in this European Standard excludes devices that act as weakly damped resonators. Some devices will depart significantly from these requirements and in these cases, care is needed in interpreting the results.

This document describes a test method for measuring a quantity representative of the intrinsic characteristics of airborne sound insulation for rail noise barriers and related devices: the sound insulation index.
The test method is intended for the following applications:
-   determination of the intrinsic characteristics of airborne sound insulation of noise barriers and related devices to be installed along railways, to be measured either on typical installations alongside railways or in laboratory conditions;
-   determination of the intrinsic characteristics of airborne sound insulation of noise barriers and related devices in actual use;
-   comparison of design specifications with actual performance data after the completion of the construction work;
-   verification of the long-term performance of noise barriers and related devices (with a repeated application of the method);
-   interactive design process of new products, including the formulation of installation manuals.
The test method is not intended for the determination of the intrinsic characteristics of airborne sound insulation of noise barriers and related devices to be installed in reverberant conditions, e.g. inside tunnels or deep trenches or under covers.
Results are expressed as a function of frequency in one-third octave bands, where possible, between 100 Hz and 5 kHz. If it is not possible to get valid measurement results over the whole frequency range indicated, the results need to be given in a restricted frequency range and the reasons for the restriction(s) need to be clearly reported.

This document specifies a normalized railway noise spectrum for the evaluation and assessment of the acoustic performance of devices designed to reduce airborne railway noise near railways.
All noise reducing devices different from noise barriers and related devices acting on airborne sound propagation, e.g. devices for attenuation of ground borne vibration and on board devices are outside of the scope of this document.

This document specifies a range of requirements and recommendations for the elements of construction, building assemblies, components, fittings and products that relate to the design and constructional aspects of usability and accessibility of buildings, i.e. access to buildings, circulation within buildings, egress from buildings during normal conditions, and evacuation in the event of a fire.
This document also applies to the common spaces in multi-unit residential buildings. Recommendations regarding residential units are given in Annex A.
This document also contains provisions with respect to outdoor features directly concerned with access to a building or a group of buildings from a relevant site boundary, or between such a group of buildings within a common site. This document does not deal with elements of the external environment, such as public open spaces, whose function is self-contained and unrelated to the use of a specific building.
This document is applicable to new buildings and new work in existing buildings.
This document introduces the concept of ‘exceptional considerations for existing buildings’ for situations where it is exceptionally difficult to meet the requirements specified and, thus, impossible to provide full accessibility. By means of ‘exceptional considerations for existing buildings’, an acceptable, though restricted, level of accessibility is specified. An exceptional consideration for existing buildings is not to be applied in other situations or invoked in an unjustified manner, or as an excuse for not achieving a higher level of accessibility, where this is economically and/or technically feasible.
The dimensions stated in this document, relevant to the use of wheelchairs, are related to the footprint of commonly used wheelchair sizes and users as specified in ISO 7176-5 and ISO/TR 13570-2, 800 mm wide and 1 300 mm long.
This document is primarily written for adults with disabilities, but it includes some recommendations on specific accessibility needs of children.

This European Standard specifies the relevant characteristics of geotextiles and geotextile-related products used in the construction of railways, and the appropriate test methods to determine these characteristics.
The intended use of these geotextiles or geotextile-related products is to fulfil one or more of the following functions: filtration, separation, and reinforcement.
The separation function will always occur in conjunction with filtration or reinforcement, and hence will not be specified alone.
This European Standard applies in superstructure-ballast or substructure-blanket layer, within a sub-grade.
This European Standard is not applicable to geosynthetic barriers, as defined in EN ISO 10318 1.
This European Standard provides for the assessment and verification of constancy of performance of the product to this European Standard and for factory production control procedures.
Particular application cases may contain requirements regarding additional properties and – preferably standardized – test methods, if they are technically relevant.
This European Standard may be used to derive design values by taking into account factors within the context of the definitions given in EN 1997 1 (Eurocode 7), e.g. factors of safety. The design life of the product should be determined, since its function may be temporary, as a construction expediency, or permanent, for the lifetime of the structure.

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.

Assessment of actions to be used in the structural design of buildings and civil engineering works where they are required to give adequate performance in fire exposure.

(1) EN 1991-1-1 gives design guidance and actions for the structural design of buildings and civil engineering works including some geotechnical aspects for the following subjects:
-   Densities of construction materials and stored materials;
-   Self-weight of construction  works;
- Imposed loads for buildings.
(2) Section 4 and Annex A give nominal values for densities of specific building materials, additional materials for bridges and stored materials. In addition for specific materials the angle of repose is provided.
(3) Section 5 provides methods for the assessment of the characteristic values of self-weight of construction works.
(4) Section 6 gives characteristic values of imposed loads for floors and roofs according to category of use in the following areas in buildings:
- residential, social, commercial and administration areas;
- garage and vehicle traffic areas;
- areas for storage and industrial activities;
- roofs;
- helicopter landing areas.      
(5) The loads on traffic areas given in Section 6 refer to vehicles up to a gross vehicle weight of 160 kN. The design for traffic areas for heavy vehicles of more than 160 kN gross weight needs to be agreed with the relevant authority. Further information may be obtained from EN 1991-2.
(6) For barriers or walls having the function of barriers, horizontal forces are given in Section 6. Annex B gives additional guidance for vehicle barriers in car parks.
NOTE  Forces due to vehicle impact are specified in EN 1991-1-7 and EN 1991-2.
