47、hat can be applied to 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 (for example safety distances, surface temperature, noise); type-B2
48、 standards on safeguards (for example 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-B standard as stated in IS
49、O 12100.The requirements of 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 part of ISO 13849 specifies the validation process for the safety functions, categories and p
