3、art of validity This standard takes effect on 1 January 2010. National foreword This standard includes safety requirements. This standard has been prepared by Technical Committee CEN/TC 151 “Construction equipment and building material machines Safety” (Secretariat: DIN, Germany). The responsible Ge
4、rman body involved in its preparation was the Normenausschuss Maschinenbau (Mechanical Engineering Standards Committee), Working Committee NA 060-13-06 AA Baugerte of Section Bau- und Baustoffmaschinen. Representatives of manufacturers and users of machines and equipment to process building material
5、s 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 98/37/EC (valid until 28 December 2009), and the “revised Machinery Directive”, Di
6、rective 2006/42/EC, which takes effect on 29 December 2009, and which apply to machines that 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 the directives. Once this standard is cited in
7、the Official Journal of the European Union, it is deemed a “harmonized” standard and thus, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (“presumption of conformity”). The European and International Standards referred to in clause 2 and
8、in the bibliography have been published as the corresponding DIN EN, DIN EN ISO or DIN ISO Standards with the same number. For the International Standard ISO 16031-1 referred to in this standard, there is no national standard available. Amendments This standard differs from DIN EN 12348:2000-11 as f
9、ollows: a) The foreword has been revised. b) Subclause 7.1 “Marking” has been revised. c) In subclause A.6, the sound pressure level has been brought in line with Directive 2006/42/EC. d) Annex D “Vibration test code” has been added. e) Annex ZA (informative) “Relationship between this European Stan

DIN EN 12348:2010-01 EN 12348:2000+A1:2009 (E) 4 Introduction This European standard is a Type C-standard as stated in !EN ISO 12100
27、-1“. The machinery concerned and the extent to which hazards are covered are indicated in the scope of this standard. This European standard has been prepared by taking into account the safety requirements of EN 791:1995 which are applicable to core drilling machines on a stand. 1 Scope This Europea
28、n Standard applies to core drilling machines on transportable stands equipped with a diamond core drill bit, usually with a water supply connection device, and intended to drill holes into stone, concrete and similar mineral materials in a stationary position where the power for the tool rotation is
29、 supplied by an electrical, hydraulic, pneumatic or internal combustion prime motor. The feed movement of the drill head and core drill bit may be effected by manual, mechanical or hydraulic means. This European Standard deals with all significant hazards pertinent to core drilling machines on a sta
30、nd when used as intended and under the conditions foreseen by the manufacturer (see clause 4). This standard specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards. This standard does not apply to: percussive or rotary-percussive rock drills ei
31、ther mounted or unmounted; hand held power drills; hydraulic or pneumatic power supply sources; mobile undercarriages to which machines can be fitted. This European Standard does not apply to machinery covered by EN 791:1995. This European Standard covers electrical hazards by making reference to re
32、levant European Standards (see 5.2). Those hazards that are relevant for all mechanical, electrical, hydraulic and other equipment of machinery and that are dealt with in standards for common use are not covered by this European Standard. Reference to pertinent standards of this kind is made where s
33、uch standards are applicable and so far as is necessary. In this European Standard, core drilling machines on a stand are called “machines“ and diamond core drill bits are called “tools”. NOTE The term “diamond“ is used as a generic word which covers all varieties of abrasive products such as diamon
34、d, borum nitride. This European Standard applies primarily to machines which are manufactured after the date of approval of the standard by CEN.
