The QNX® Neutrino® RTOS Safe Kernel has been certified by Sira to conform to IEC 61508 at Safety Integrity Level 3 (SIL 3). As such, it provides a certified platform on which application developers can implement safety critical systems that must meet the most stringent functional safety requirements.

QNX Neutrino RTOS Safe Kernel 1.0, which is based on QNX SDP 6.5.0, contains the following components:

The QNX Neutrino RTOS Safe Kernel is supported on multiple hardware platforms, including x86, Power and ARM with multi-core capabilities through SMP.

Functional safety management

QNX Neutrino Safe Kernel RTOS

Functional safety management is the "language" that connects safety-related applications.


The QNX Neutrino RTOS Safe Kernel incorporates many key characteristics required of an IEC 61508 SIL 3 certified system. These include:


Sira is a world leader in IEC 61508 functional safety certification services, and the United Kingdom's leading notified body for Ex product certification (ATEX and IECEx). It is accredited by the United Kingdom Accreditation Service (UKAS) to carry out its certification activities in accordance with the CASS scheme (Conformity Assessment of Safety-related Systems).

IEC 61508

IEC 61508 codifies practices and standards associated, not only with the production of code for mission- and safety- critical systems, but also with the resulting product. IEC 61508 provides recommendations or requirements for:

  • Processes to be applied during the development lifecycle of software used in critical applications
  • Techniques and tools to be applied to the software
  • Target failure measures for systems acting in low demand, high demand or continuous mode.
