-   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 European Standard. 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 European Standard 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

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by April 2009, and conflicting national standards shall be withdrawn at the latest by December 2009. This document includes Amendment 1, approved by CEN on 2008-09-09. This document supersedes EN 12336:2005. The start and finish of text introduced or altered by amendment is indicated in the text by tags ! ". This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EC Directive(s). !For relationship with EC Directive(s), see informative Annexes ZA and ZB, which are integral parts of this document." This European Standard includes a Bibliography. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

EN 12336:2005+A1:2008 (E) 5 Introduction This European Standard is a type C standard as stated in EN ISO 12100-1:2003. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this document. When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard. In this European Standard it is assumed that:  only competent persons operate the machine;  components without specific requirements are: a) designed in accordance with the usual engineering practice and calculation codes, including all failure modes; b) of sound mechanical and electrical construction according to the state of the art; c) made of materials with adequate strength and of suitable quality; d) made of no harmful materials, such as asbestos;  components are kept in good repair and working order, so that the required characteristics remain despite wear;  the installation allows a safe use of the machine;  negotiation occurs between the manufacturer and the user/purchaser concerning particular conditions of use and the places (e. g. ground and local safety conditions) of use of the machinery. NOTE “Manufacturer” is understood within the European Union as intended in the Machinery Directive. SIST EN 12336:2005+A1:2008

EN 12336:2005+A1:2008 (E) 6 1 Scope 1.1 Description of the machines This European Standard 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 European Standard. 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 European Standard 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 Clause 4). 1.3 Validity This European Standard is not applicable to machines which are manufactured before the date of publication of this European Standard by CEN.
