CEN/TC 143/WG 1 - Metal forming machine tools - Safety

This document, in addition to ISO 16092-1, specifies technical safety requirements and measures to be adopted by persons undertaking the design, manufacture and supply of the following groups of mechanical presses and mechanical press production systems:
—     Group 1: Presses with a part revolution clutch(es);
—     Group 2: Presses with a servo drive system (Mechanical servo presses).
NOTE 1  Requirements in this document are essentially applicable to both groups of the mechanical press. If a requirement applies to only one group, then the group is specified.
NOTE 2  Other types of motorized drive systems provide similar functionalities to what is commonly called "servo drives" or "servo motors", and as such their use is considered the same within the terms used in this document (e.g. variable frequency drive systems).
The presses covered by this document range in size from small high-speed machines with a single operator producing small workpieces to large relatively slow-speed machines with several operators and large complex workpieces.
This document deals with all significant hazards relevant to mechanical presses and ancillary devices (e.g. moving die cushions, work-piece ejectors, feeding and transfer systems) which are integral to the machine, when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). All phases of the machine life cycle as described in ISO 12100:2010, 5.4 have been taken into consideration.
NOTE 2  All significant hazards means those identified or associated with presses at the time of the publication of this document.
In addition to machines not covered by ISO 16092-1:2017, this document does not cover machines which:
a)   transmit energy to impart press slide motion by using hydraulic or pneumatic means;
b)   have two or more slides moving in different angular orientations from each other;
NOTE 3 This document applies to presses which have two or more slides moving in the same angular orientations, e.g. a press which has inner and outer slides.
c)   transmit energy to impart press slide motion by using a linear motor mechanism(s).

ISO 16092-1:2017 applies to presses which can function independently and can also be used as a guide for the design of presses which are intended to be integrated in a manufacturing system.
The covered presses transmit force mechanically to cut, form, or work cold metal or other sheet materials by means of tools or dies attached to or operated by slides/ram in range in size from small high speed machines with a single operator producing small workpieces to large relatively slow speed machines with several operators and large workpieces.
