Part 2 Requirements for particul
16、ar types of tool which either supplement or modify the requirements given in Part 1 to account for the particular hazards and characteristics of these specific tools. This European Standard has been prepared under a mandate given to CEN/CENELEC by the European Commission and the European Free Trade

31、r supply may include water source from a pipe or tank or vat). 2 Definitions This clause of Part 1 is applicable except as follows: 2.101 diamond drill tool with water supply designed to drill stone and concrete by means of diamond core-bits. The tool at least consists of a drill unit and a drill st
32、and to which it is fixed. The drill stand is attached to the material to be drilled by means of dowels, vacuum or other suitable devices (see Figure Z101) or it is secured to an appropriate support (like e.g. scaffolding) that, under working forces transmitted by the drill stand, is not subjected to
33、 a displacement with reference to the base material 2.102 water-collecting ring a device to collect water and stone-mud when drilling 2.103 drill unit the drill unit at least consists of a motor, gear unit and a fitting for the drill bit 2.104 pillar part of the drill stand to which the drill unit i
