Safety of machine tools - Hydraulic press brakes

This European Standard specifies technical safety requirements and protective measures to be adopted by persons undertaking the design, manufacture and supply of hydraulic press brakes which are designed to work cold metal or material partly of metal and hereafter referred to as machines.
This European Standard also covers hydraulic press brakes, whose primary intended use is the cold working of metal, which are to be used in the same way to work other sheet materials such as cardboard or plastic.
The requirements in this European Standard take account of intended use, including foreseeable misuse as defined in 3.22 of EN ISO 12100-1:2003. This European Standard presumes access to the press brake from all directions, deals with the hazards described in Clause 4, and specifies the safety measures for both the operator and other exposed persons.
This European Standard also applies to:
- ancillary devices which are an integral part of the press brake, e.g. back gauges and adjustable front sheet supports;
- machines which are integrated into an automatic production line where the hazards and risk arising are comparable to those of machine working separately.
The requirements of this European Standard apply to all hydraulic press brakes whatever the technology used in their control system, e.g. electromechanical and/ or electronic.
This European Standard does not apply to machines whose principal designed purpose is:
a)   sheet folding by rotary action;
b)   tube and pipe bending by rotary action;
c)   roll bending.
This European Standard applies to machines built after the date of issue of this European Standard.
This European Standard does not cover the safety aspect of automatic loading and unloading equipment.
Some guidance how to take into account additional automatic loading and unloading equipment can be found in ISO 11161.

5.1.1 Description of the safeguarding of access to moving parts 5.1.1.1 General The major danger zones at hydraulic press brakes are the tools, associated area and ancillary loading and unloading devices which are an integral part of the machine. Preventive measures shall be taken to deal with the relevant hazards. Safeguarding measures described in EN ISO 12100-1 and EN ISO 12100-2 which are appropriate for the protection of any operator at the tools are listed below. Designers, manufacturers and suppliers shall select the safeguarding methods which reduce the risks as far as possible, considering the significant hazards (see Table 1) and the mode of production. The selected combination of safeguarding methods shall protect all exposed persons, i.e. those who can gain access to the danger zone during operation, setting, maintenance, cleaning and inspection activities. Access to the danger zone(s) shall be prevented by one or a combination of the following safeguarding measures. 5.1.1.2 Fixed enclosing guards Fixed enclosing guards shall comply with EN 953. They shall be firmly secured to the machine, another rigid structure or the floor. Any openings in the guards or between the guard and the machine shall meet the requirements of EN ISO 13857:2008, Table 4. 5.1.1.3 Interlocking guards with or without guard locking Interlocking guards shall comply with EN 953 and prevent, in conjunction with fixed guards, access to the danger zone, during any dangerous movement. Initiation of the dangerous movement shall be prevented until the guard is closed. The associated interlocking devices shall be designed and constructed in accordance with 6.2.1 of EN 1088:1995, for occasional access and with 6.2.2 of EN 1088:1995, for frequent access
Interlocking guards without guard locking shall be placed in such a position that the operator does not have time to reach the danger zone before any dangerous movement has ceased (see EN 999 and EN ISO 13857).
