This document (EN 12110:2014) has been prepared by Technical Committee CEN/TC 151 “Construction equipment and building material machines S

5、afety” (Secretariat: DIN, Germany). The responsible German body involved in its preparation was the DIN-Normenausschuss Maschinenbau (DIN Standards Committee Mechanical Engineering), Working Committee NA 060-13-04 AA Tunnelbaumaschinen of Section Bau- und Baustoffmaschinen. Representatives of manufa

6、cturers and users of tunnelling machinery, and of the employers liability insurance associations contributed to this standard. This standard contains specifications meeting the essential requirements set out in Annex I of the “Machinery Directive”, Directive 2006/42/EC, and which apply to machines t

7、hat are either first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of compliance with the essential requirements of that directive. Once this standard is cited in the Official Journal of the European Union, it is deemed a “harmonized” standard and thus

8、, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (“presumption of conformity”). The European Standards referred to in Clause 2 and in the Bibliography of the EN have been published as the corresponding DIN EN or DIN EN ISO Standards with

9、the same number. Where the International Standards referred to are not also DIN ISO Standards with the same number, there are no national standards available. Amendments This standard differs from DIN EN 12110:2010-02 as follows: a) normative references have been updated; b) Clause 3 “Terms and defi

10、nitions” and Clause 4 “List of significant hazards” have been revised; c) safety requirements in Clauses 5 and 6 and the information for use in Clause 7 have been revised; d) Annex ZA (informative) “Relationship between this European Standard and the Essential Requirements of EU Directive 2006/42/EC

11、” has been updated.

The machinery and equipment concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scop

26、e 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 provision

27、s of this type C standard. EN 12110:2014 (E) DIN EN 12110:2014-10 5 1 Scope This European Standard applies to the design, construction, equipping, marking and testing of air locks as defined in 3.3 including pressure bulkheads as defined in 3.4, which are to be used in tunnelling work. An oxygen bre

28、athing system used to provide the breathing supply necessary to conduct a safe decompression is also covered by this standard. This European Standard is not applicable to machinery and equipment which is manufactured before the date of publication of this document by CEN. NOTE Air locks can be conne

29、cted to tunnelling machinery. This standard can help the design of air locks and bulkheads in other compressed air work in construction. This European Standard deals with all significant hazards, hazardous situations and events relevant to such machinery when they are used as intended and under cond

30、itions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). This European Standard does not cover the supply of services to the air lock. Vibration, noise and EMC (Electromagnetic compatibility) hazards are not significant hazards for air locks. This European Standard does

31、not cover the hazards due to the mobility of the machinery. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
