BS EN provides information on: the underlying concepts of risk and the relationship of risk to safety integrity (see Clause A.4);. BS EN , Functional safety – Safety instrumented systems for the process industry sector, is the benchmark standard for the management. IEC is available as IEC RLV which contains the International Standard and its Redline version, showing all.

SIS SIS are instrumented systems that provide a significant level of risk reduction against accident hazards. An SIS may implement one or more safety instrumented functions SIFswhich are designed and implemented to address a specific process hazard or hazardous event.

This standard defines the functional safety requirements established by IEC in process industry sector terminology. Find Similar Items This product falls into the following categories.

Electrical standards Safety Industrial processes. The process sector standard does not cover nuclear power facilities or nuclear reactors.

The essential roles of the various personnel assigned responsibility for the SIS should be defined and procedures developed, as necessary, to support the consistent execution of their responsibilities. In certain limited cases, alarm systems may provide significant accident risk reduction, where they also might be considered as a SIS. IEC is generic functional safety standard, providing the framework and core requirements for sector specific standard.
