This European 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 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 stand 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 either 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 relevant 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 such 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 diamond, borum nitride. This European Standard applies primarily to machines which are manufactured after the date of approval of the standard by CEN.
