1 Scope
This International Standard provides a vocabulary for the various types of hydraulic tools , fixed and portable, and for the attachments that are used with them. The terms are given by category: general, tools for removing and shaping material, tools for assembly work.
NOTE 1 The use of the terms “tool” and “machine” can be confusing in the field of hydraulic powered tools. “ Hydraulic tool ” is used for hand-held machines and “fixed hydraulic tool ” for larger machines, often suspended or mounted on a carrier. However, the terms “tool” and “bit” are also used for the inserted drill , file, chisel, etc. that is fitted to the machine spindle. In order to differentiate between hydraulic tool and inserted tool, the term “ power tool ” can be used for the former.
NOTE 2 Individual tools are usually designed to operate within a maximum specific flow category given by the European Hydraulic Tools Manufacturer Association (EHTMA). Some hydraulic tools incorporate a flow control to limit maximum speed or provide adjusting speed.
