ISO 13849-1
Safety-Related Parts of Control Systems
ISO 13849 is the machinery safety standard for safety-related parts of control systems. It expresses risk reduction as targets and achieved PL for each safety function.
It is widely used for emergency stop, guard interlock, safe speed, safe torque off, light curtain, and robot-cell safeguarding functions. Evidence usually combines risk assessment, architecture category, component reliability data, diagnostics, and validation.
CSA helps define PLr, review SISTEMA-style calculations, validate safety functions, prepare technical-file evidence, train controls teams, and provide machinery safety staffing.
