International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the Internati

In particular the different approval criteria needed for the differen

29、 13850:2015(E)IntroductionThe structure of safety standards in the field of machinery is as follows.a) Type-A standards (basic safety standards) give basic concepts, principles for design, and general aspects that can be applied to machinery.b) Type-B standards (generic safety standards) deal with o

30、ne or more safety aspect(s) or one or more type(s) of safeguard that can be used across a wide range of machinery: type-B1 standards on particular safety aspects (e.g. safety distances, surface temperature, noise); type-B2 standards on safeguards (e.g. two-hands controls, interlocking devices, press

31、ure sensitive devices, guards).c) Type-C standards (machinery safety standards) deal with detailed safety requirements for a particular machine or group of machines.This International Standard is a type-B2 standard as stated in ISO 12100.When provisions of a type-C standard are different from those

32、which are stated in type-A or type-B standards, the provisions of the type-C standard take precedence. ISO 2015 All rights reserved vBS EN ISO 13850:2015BS EN ISO 13850:2015Safety of machinery Emergency stop function Principles for design1 ScopeThis International Standard specifies functional requir

33、ements and design principles for the emergency stop function on machinery, independent of the type of energy used.It does not deal with functions such as reversal or limitation of motion, deflection of emissions (e.g. radiation, fluids), shielding, braking or disconnecting, which can be part of the

34、emergency stop function.The requirements for this International Standard apply to all machines, with exception to: machines where an emergency stop would not reduce the risk; hand-held or hand-operated machines.NOTE The requirements for the realization of the emergency stop function based on electri

47、itiated by a single human action.4.1.1.2 The emergency stop function shall be available and operational at all times. It shall override all other functions and operations in all operating modes of the machine without impairing other protective functions (e.g. release of trapped persons, fire suppres

The reset shall not initiate machine start up.NOTE The emergency stop function cannot be considered as measure of prevention of unexpected start up as described in ISO 12100.4.1.1.3 The emergency stop function is a complementary protective measure and shall not be applied as a substitute for safeguarding measures and other functions or safety functions.4.1.1.4 The emergency stop fu
