ISO 10815:2016 establishes the basic principles for measuring, processing and evaluating vibration generated internally in railway tunnels by the passage of trains. By establishing a standard procedure, comparative data may be obtained on response of the tunnel elements from time to time, provided that the excitation source is the same. Data obtained in different tunnels may also be compared. The measurements considered in ISO 10815:2016 concern the response of the structure and secondary elements mounted in the tunnel. They do not concern the response of persons in the tunnel or in its vicinity, or of passengers on trains running through the tunnel.

This European Standard specifies evacuation lighting in road tunnels longer than 500 m and with an AADT (Annual Average Daily Traffic) higher than 500 vehicles to facilitate the safe evacuation of vehicle occupants in evacuation situations such as fire. It addresses the fundamental issues of evacuation lighting for evacuation routes, emergency exits and cross connections, as well as giving some practical advice regarding aspects of installation and maintenance in road tunnels. It is intended to be used in conjunction with CEN/CR 14380:2003 or relevant national standards for road tunnel lighting. The recommendations may be applied to tunnels up to 500 m in length, especially where conditions such as high traffic volume, or severe curvature or gradient apply. It specifies lighting levels and general provisions for evacuation lighting installations that, based on experience, are considered to be necessary for the safety of people driving through road tunnels in case of an incident and particularly in case of fire. However, as there are different types of road tunnels, both in construction and traffic conditions, various types of incident may occur. This standard should be considered as a list of minimum prescriptions for evacuation lighting in tunnels, to be completed by means of specific risk analysis for the particular tunnel. The design of marking and safety signs is not part of this standard.

ISO 14837-1:2005 provides general guidance on ground-borne vibration generated by the operation of rail systems, and the resultant ground-borne noise in buildings. It lists the factors and parameters that need to be taken into consideration and offers guidance on prediction methods appropriate for a range of circumstances (e.g. to support the assessment of effects on human occupants and sensitive equipment or operations inside the buildings in addition to the predictions required to assess the risk of damage to building structures). Attention is paid in ISO 14837-1:2005 to characteristics of the source: emission (e.g. train, wheel, rail, track, supporting infrastructure); propagation path: transmission (e.g. ground condition, distance); and receiving structures: immission: (e.g. foundations, form of building construction). The guidance covers all forms of wheel and rail systems, from light-rail to high-speed trains and freight. ISO 14837-1:2005 provides guidance for rail systems at-grade, on elevated structures and in tunnels. It does not deal with vibration arising from the construction and maintenance of the rail system. It does not deal with airborne noise. Structure-radiated noise from elevated structures, which can have a significant environmental impact, is also excluded.

This standard is valid for all road tunnels and underpasses which are used by the motorised traffic, and which are decided to be lighted.

NOTE   Directive 94/9/EC concerning equipment and protective systems intended for use in potentially explosive atmos-pheres can be applicable to the type of machine or equipment covered by this European Standard. The present standard is not intended to provide means of complying with the essential health and safety requirements of Directive 94/9/EC.

1.1   Description of the machines
This document is applicable to all types of shield machines and associated back up equipment, thrust boring machines, auger boring machines and lining erection equipment. It specifies the essential safety requirements for the design, installation, maintenance, and information for use of such machines.
Shield machines and associated back up equipment include:
-   open shields for both manual and mechanical excavation;
-   shielded tunnel boring machines;
-   micro tunnelling machines;
-   towed or stationary back up equipment;
-   pipe jacking equipment.
All shield machines provide lateral and radial ground support. In addition they may provide various types of face support and ground water control (see Clause 3).
Certain associated matters are not included in the scope of the standard:
-   additional equipment which may form an integral part of a shield machine or back up equipment and is used for compressed air (hyperbaric/plenum) working (see EN 12110:2002);
-   use under hyperbaric conditions;
-   the supply of electricity up to the machine;
-   ancillary tools and equipment used for, at or on the machine;
-   electromagnetic compatibility;
-   loading and transport equipment which is not an integral part of the machine, e.g. rolling stock, man riders, grout cars, segment cars, muck cars.
NOTE   Within the European Union Directive 94/9/EC concerning equipment and protective systems intended for use in potentially explosive atmospheres can be applicable to the type of machine or equipment covered by this document. The present document is not intended to provide means of complying with the essential health and safety requirements of Directive 94/9/EC.
1.2   Hazards
This document deals with significant hazards, hazardous situations and events relevant to shield machines and associated back up equipment, thrust boring machines and auger boring machines when they are used as intended and under the conditions foreseen by the manufacturer (see Cl

This standard is applicable to unshielded tunnel boring machines, TBMs, and rodless shaft boring machines, SBMs, and their towed or attached back-up equipment for driving tunnels or shafts in rock where the whole area is excavated in one or more steps by mechanical means. It specifies essential safety requirements for the design, construction and maintenance of such machines when used in non-explosive atmosphere together with the methods of verification. The standard specifies monitoring for hazardous atmospheres.  For TBMs and SBMs which are to be used continuously in explosive atmosphere, additional relevant standards alos apply.  This European Standard deals with all significant hazards pertinent to unshielded tunnel boring machines and rodless shaft boring machines for rock, when they are used as intended and under the conditions foreseen by the manufacturer (see clause 4). This European Standard specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazard.
