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 applicable to unshieldsed tunnel boring machines, TBM's, and rodless shaft boring machines, SBM's, 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.

This European Standard specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards.
1.2   Description of the machines
The general term "unshielded tunnel boring machines" encompasses various kinds of machines for mechanical excavation of underground openings such as tunnels and inclined shafts. This is done in a continuous process, without blasting, using a rotating cutter head.
Depending on the hardness of the material being excavated, tools of different types are used to cut the rock. Normally, rolling discs are employed in medium to very hard rock. All tunnel boring machines, TBM's, and rodless shaft boring machines, SBM's, have the tools mounted on a cutter head which rotates under thrust against the rock. The torque required to rotate the cutter head is developed by electric or hydraulic motors and the thrust is normally delivered by hydraulically powered cylinders.
The torque and thrust reactions created by a TBM or SBM have to be resisted by anchoring the complete machine inside the bore itself by means

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 hazards.
1.2   Description of the machines
The general term "unshielded tunnel boring machines" encompasses various kinds of machines for mechanical excavation of underground openings such as tunnels and inclined shafts. This is done in a continuous process, without blasting, using a rotating cutter head.
Depending on the hardness of the material being excavated, tools of different types are used to cut the rock. Normally, rolling discs are employed in medium to very hard rock. All tunnel boring machines, TBM's, and rodless shaft boring machines, SBM's, have the tools mounted on a cutter head which rotates under thrust against the rock. The torque required to rotate the cutter head is developed by electric or hydraulic motors and the thrust is normally delivered by hydraulically powered cylinders.
The torque and thrust reactions created by a TBM or SBM have to be resisted by anchoring the complete machine inside the bore itself by means

This European Standard specifies the relevant characteristics of geotextiles and geotextile-related products used in the construction of tunnels and underground structures, and the appropriate test  methods to determine these characteristics. The intended use of these geotextiles or geotextile-related products is to protect geomembranes used in tunnels and underground structures. This standard is not applicable to geomembranes. This standard provides for the evaluation of conformity of the product to this European Standard and for factory production control procedures. This standard defines requirements to be met by manufacturers and distributors with regard to the presentation of product properties.  NOTE 1  Particular application cases or national specifications may contain requirements regarding additional properties and - preferably standardised - test methods, if they are technically relevant and not conflicting with European Standards. NOTE 2  This European Standard may be used to derive design values by taking into account factors within the context of the definitions given in Eurocode 7 (ENV 1997-1), 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.
