Whether it is a sensor, a mechanical valve, a complex measurement system, a firmware logic resolver, or embedded software intended to be integrated into a security loop, the requirement is the same: validate the conformity of the product for use in safety applications via the Safety Life Cycle established by the series of IEC 61508 standards.

Our SIL consulting service includes complete conformity assessment of the product, component, or complex integrated system for all SILs (SIL 1, SIL 2, SIL 3, and SIL 4).
The service we offer is complete SIL consulting, highly specialized in creating and implementing all the phases of the Safety Life Cycle: our pool of functional safety specialists will guide you through the entire process for device hardware and software/firmware assessment according to the IEC 61508 standard.

The SIL consulting approach is structured on a series of modular activities that can be carried out based on specific needs:

  • SIL Allocation
  • Support in drawing up the Safety Requirements Specification document
  • Hardware and software design review for conformity to IEC 61508 requirements
  • Validation testing, including software validation, and drawing up the test report
  • Overall validation at system installation

FAQ

Functional safety is the branch of engineering that deals with safety systems equipped with electrical, electronic, and programmable electronic technology (E/E/PE) and is regulated by the international IEC 61508 standard. The goal of functional safety is to certify that there are no unacceptable risks that can cause physical injuries, direct or indirect harm to people or the environment. To this end, the IEC 61508 standard requires, where necessary, the implementation of safety systems capable of protecting people or the environment from such risks.

SIL stands for Safety Integrity Level. The IEC 61508 standard defines the SIL as the likelihood of a system carrying out a safety function at the time it is needed. A system’s SIL ranges from 1 to 4, where 4 is the maximum safety level.

The IEC 61508 standard is the basic international technical-legislative reference for functional safety that defines the minimum requirements for equipment and systems to be used in the various industrial sectors, for which some specific standards regulate proper implementation of these minimum requirements to the specific sectors; for example, the IEC 61513 standard for the nuclear sector, EN 60601 for medical devices, ISO 26262 for the automotive sector, IEC 61511 for the process industry, IEC 62061 for machinery, the EN 50126/8/9 series for railways, etc.
