BS EN ISO 13849-1:2015 pdf free.Safety of machinery — Safety — related parts of control systems.
1Scope:This part of IS0 13849 provides safety requirements and guidance on the principles for the designand integration of safety-related parts of control systems (SRP/cS), including the design of software.For these parts of SRP/Cs, it specifies characteristics that include the performance level required forcarrying out safety functions. it applies to SRP/CS for high demand and continuous mode, regardless ofthe type of technology and energy used (electrical, hydraulic, pneumatic, mechanical, etc.), for all kindsof machinery.
lt does not specify the safety functions or performance levels that are to be used in a particular case.This part of lSo 13849 provides specific requirements for SRP/CS using programmable electronicsystem(s).
lt does not give specific requirements for the design of products which are parts ofSRP/CS.Nevertheless,the principles given, such as categories or performance levels, can be used.
NOTE1 Examples of products which are parts of SRP/CS: relays, solenoid valves, position switches,PLCS,motor control units, two-hand control devices, pressure sensitive equipment.For the design of such products,it is important to refer to the specifically applicable International Standards, e.g. IS0 13851, ISo 13856-1 andISO 13856-2.
NOTE2 For the definition of required performance level, see 3.1.24.
NOTE3 The requirements provided in this part of lSo 13849 for programmable electronic systems arecompatible with the methodoiogy for the design and development of safety-related electrical, electronic andprogrammable electronic control systems for machinery given in lEC 62061.
NOTE4 For safety-related embedded software for components with PlL = e , see IEC 61508-3:1998,Clause 7.
2.Normative references:The following documents, in whole or in part, are normatively referenced in this document and areindispensable for its application. For dated references,only the edition cited applies.For undatedreferences, the latest edition of the referenced document (including any amendments) applies.IS0 12100:2010,Safety of machinery —General principles for design – Risk assessment and risk reductionIS0 13849-2:2012,Safety of machinery —Safety-related parts of control systems — Part 2:ValidationIEC 60050-191:1990, International electrotechnical vocabulary -Chapter 191: Dependability and qualityof service.Amended by lEC 60050-191-am1:1999 and lEC 60050-191-am2:2002:1999
