Standards Development

Scope

This document specifies technical safety requirements and protective measures to be adopted by persons undertaking the design, manufacture and supply of folding and longbending machines which are designed to work cold metal or material partly of metal and hereafter referred to as machines. This document also covers folding and longbending machines, 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 standard take account of intended use, including reasonably foreseeable misuse as defined in 3.24 of ISO 12100:2010. This document 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 document also applies to:

- ancillary devices which are an integral part of the press brake, e.g. back gauges and cutting devices;

- 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 document apply to all folding and longbending machines whatever the technology used in their control system, e.g. electromechanical and/or electronic or pneumatic. This document is not applicable to folding and longbending machines manufactured before the date of its publication. This document 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 11161:2007.

Purpose

The aim is the creation of a type C standard, specific for the two types of folding machines, referring to applicable level B standards. This including common definitions of the main parts and -functions of the machine, as the minimum safety requirements. Goal is also to standardize specific safety functions, and specific safety devices, applicable to achieve a minimum acceptable safety level. The standard will harmonize safety functions and solutions among various constructors, ease surveillance of the market, and increase safe use of the machine by the final user.
