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.

The global description "wall saw and wire saw equipment" contains two differing types of machines for use in the construction industry, and both used to make cuts on walls, ceilings and floors composed of mineral construction materials and/or composite materials. The many different cutting tasks and choice of operating method determine the type of machine to be used for each application.
The machines may therefore be split into the following two principal classifications:
-   Wall saws - exclusively rail guided - transportable.
-   Wire saws - transportable.
The machines are intended for the use of diamond tools. The types of cutting tools used in conjunction with the machines as described above fall within the design and use parameters supplied by the manufacturer.
Cutting debris generated by the cutting action is removed from the cutting joint by a medium such as water directed to the cutting tool.
Machines covered by this standard may be powered by: electric motor, IC engine, electro-hydraulic drive and IC engine-hydraulic drive.
