Scope

This document applies to core drilling machines on transportable stands equipped with a diamond or similar superabrasive core drill bit, with or without 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 drill unit can be equipped with a soft impact device.

The feed movement of the drill head and core drill bit can be effected by manual, electrical, hydraulic or pneumatic means.

This document deals with all significant hazards, hazardous situations and hazardous events relevant to core drilling machines on a stand, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Annex A).

This document specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards associated during the lifetime of the machine, see EN ISO 12100:2010, 5.4.

This document 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;

      machinery for drilling and foundation equipment (which is covered by EN 16228-1:2014 to -7:2014);

      machinery with electric main motor ≤ 3,7 kW which is covered by EN 62841-3-6:2014.

In this document, 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 superabrasive products such as diamond, boron nitride or similar.

This document does not apply to core drilling machines on stand manufactured before the date of its publication.
