What is ISO/TR 24119- Evaluation of fault masking serial connection about?

ISO/TR 24119 is an international standard on the safety of machinery that discusses the evaluation of fault masking serial connection of interlocking devices associated with guards with potential-free contacts to ensure protection against machinery hazards. ISO/TR 24119 is a technical report that illustrates and explains principles of fault masking in applications where multiple interlocking devices with potential-free contacts (B1 to Bn) are connected in series to one logic unit (K) which does the diagnostics. ISO/TR 24119 provides guidance on how to estimate the probability of fault-masking and the maximum DC for the involved interlocking devices. IS...
