1.1 This European Standard specifies technical safety requirements and measures to be adopted by personsundertaking the design as defined in 3.11 of EN 292-1:1991, manufacture and supply of guillotine shears which areintended to work cold metal or material partly of cold metal as defined in 3.1.7 and hereafter referred as machines.1.2 This standard also covers guillotine shears whose primary intended use is to work cold metal, which are tobe used in the same way to work other sheet materials (e.g. cardboard, plastic, rubber, leather).1.3 The requirements in this standard take account of intended use, as defined in 3.12 of EN 292-1:1991. Thisstandard presumes access to the guillotine shear from all directions, deals with the hazards described in clause 4,and specifies the safety requirements and/or protective measures for both the operator and other exposed persons.1.4 This standard also applies to ancillary devices which are an integral part of the guillotine shear. Thisstandard also applies to machines which are integrated into an automatic production line where the hazards andrisk arising are comparable to those of machines working separately.1.5 This standard includes guillotine shears in which energy is imparted to the blade by a number of means. e.g.:a) mechanically driven from a motor through a friction clutch;b) through a direct drive motor and brake;c) through hydraulic pressure;d) through pneumatic pressure.1.6 This standard does not cover machines whose principal designed purpose is:a) cutting in other than a straight line (e.g. at nibbling machines);b) cutting by continuous action at crocodile shears (see 3.4).1.7 This standard does not cover the safety requirements related to the use of PES or PPS. They will be dealt withat its next revision.1.8 This standard is not applicable to machines which are manufactured before the date of publication of thisdocument by CEN.
