The FileX file management software developed alongside the ThreadX real time operating system is the first Industrial Grade commercial file management system to be certified by SGS-TÜV Saar for embedded development in safety-critical systems.
FileX has achieved the highest level of certification for IEC 61508 SIL 4, IEC 62304 Class C, ISO 26262 ASIL D, and EN 50128 SW-SIL 4 safety standards. IEC 61508 and all standards that are derived from it, including IEC 62304, ISO 26262, and EN 50128, are used to ensure the functional safety of electrical, electronic, and programmable electronic safety-related medical devices, process control systems, industrial machinery, and railway control systems.
SGS-TÜV Saar, formed through a joint venture of Germany’s SGS-Group and TÜV Saarland, is the leading accredited, independent company for testing, auditing, verifying, and certifying embedded software for safety-related systems worldwide. It has evaluated the relevant parts of Express Logic’s modified waterfall development process for FileX, with phase overlap and phase blending, to ensure that best development practices have been followed for:
- Requirements management
The Safety Manual documents these quality-assurance measures, which enable developers to use FileX in safety-critical software development for even the most rigorous Safety Integrity Level (SIL 4) and Automotive Safety Integrity Level (ASIL D) requirements, according to IEC 61508, IEC 62304, ISO 26262, and EN 50128, without further qualification.
“The achievement of SGS-TÜV Saar certification for FileX will enable our customers to simplify their certification process, thus saving project time and money and reducing risk,” said William Lamie, CEO of Express Logic. “This certification provides significant evidence of the exceptionally high quality of our FileX product.”
