DIN EN ISO 14119:2014-03 EN ISO 14119:2013 (E) 4 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

35、 to all machinery;b) Type-B standards (generic safety standards) 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 safegua

36、rds (e.g. two-hand controls, interlocking devices, pressure-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

37、 this document can be supplemented or modified by a type-C standard.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 Stan

38、dard has been prepared to give guidance to machinery designers 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 us

39、ed as a basis for verification procedures for the suitability 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

40、principles of this standard. The informative Annexes G to I 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

41、 masking of faults in series connection of interlocking devices.DIN EN ISO 14119:2014-03 EN ISO 14119:2013 (E) 5 1 ScopeThis International Standard specifies principles for the design and selection independent of the nature of the energy source of interlocking devices associated with guards.This Int

42、ernational Standard covers the parts of guards which actuate interlocking devices.NOTE ISO 14120 specifies general requirements for the design and construction of guards provided primarily to protect persons from mechanical hazards. The processing of the signal from the interlocking device to stop a
