36、19:2013ISO 14119:2013(E)IntroductionThe structure of safety standards in the field of machinery is as follows:a) Type-A standards (basic safety standards) giving basic concepts, principles for design, and general aspects that can be applied to all machinery;b) Type-B standards (generic safety standa
37、rds) dealing with one safety aspect or one type 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-hand controls, interlocking devices, pressure-
38、sensitive devices, guards);c) Type-C standards (machine safety standards) dealing with detailed safety requirements for a particular machine or group of machines.This document is a type-B2 standard as stated in ISO 12100.The requirements of this document can be supplemented or modified by a type-C s
39、tandard.For machines which are covered by the scope of a type-C standard and which have been designed and built according to the requirements of that standard, the requirements of that type-C standard take precedence.This International Standard has been prepared to give guidance to machinery designe
40、rs and writers of product safety standards on how to design and select interlocking devices associated with guards.Relevant clauses of this International Standard, used alone or in conjunction with provisions from other standards, may be used as a basis for verification procedures for the suitabilit
41、y of a device for interlocking duties.The informative Annexes A to F describe the technology and the typical characteristics of the defined 4 types of interlocking devices. Other solutions may be adopted, provided that they comply with the principles of this standard. The informative Annexes G to I
42、give information on particular aspects like interlocking devices used within safety functions, risk assessment considering the motivation to defeat and static action forces. ISO/TR 24119 is under preparation and will give information on the masking of faults in series connection of interlocking devi
