Express Logic’s NETX DUO has been used in safety-critical products within the fields of avionics, medical devices, transportation, and industrial control equipment. Developers facing IEC, FDA, or other regulatory approval requirements for safety-critical operation now have 2 solutions from Express Logic to make their job easier:
- TUV Certification
- UL Certification
Each of these solutions offers benefits for developers of safety-critical systems:
TÜV Off-the-shelf Certification
NETX DUO has been certified by SGS-TÜV Saar for use in safety-critical systems, according to IEC-61508, IEC-62304, ISO 26262 and EN 50128. The certification confirms that NETX DUO can be used in the development of safety-related software for the highest safety integrity levels of IEC 61508, IEC 62304, ISO 26262 and EN 50128 for the Functional Safety of electrical, electronic, and programmable electronic safety-related systems. SGS-TÜV Saar, formed through a joint venture of Germany’s SGS-Group and TÜV Saarland, has become the leading accredited, independent company for testing, auditing, verifying and certifying embedded software for safety-related systems worldwide. The industrial safety standard 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, automobiles and railway control systems.
SGS-TÜV Saar has evaluated the relevant parts of Express Logic’s modified waterfall development process for NETX DUO, with phase overlap and phase blending, to ensure that best development practices have been followed at these stages:
- Requirements Management
SGS-TUV Saar, as part of the certification, has reviewed the extensive test suite for NETX DUO. The NETX DUO test suite, comprised of a large number of application simulations, effectively performs functional black box testing over the entire NETX DUO. The tests exercise 100 percent of the generic NETX DUO C code, which is validated by using code coverage analysis tools. Express Logic’s NETX DUO Safety Manual documents these quality assurance measures, which enable developers to use NETX DUO in safety-critical software development for even the most rigorous Safety Integrity Level (SIL), according to IEC 61508, IEC 62304, ISO 26262 or EN 50128 without further qualification.
UL Off-the-shelf Certification
NETX DUO has been recognized by UL for compliance with UL 60730-1 Annex H, CSA E60730-1 Annex H, IEC 60730-1 Annex H, UL 60335-1 Annex R, IEC 60335-1 Annex R, and UL 1998 safety standards for software in programmable components. UL is a global, independent, safety-science company with more than a century of expertise innovating safety solutions, ranging from the public adoption of electricity to breakthroughs in sustainability, renewable energy, and nanotechnology.
Along with IEC/UL 60730-1, which has requirements for “Controls Using Software” in its Annex H, the IEC 60335-1 standard describes the requirements for “Programmable Electronic Circuits” in its Annex R. IEC 60730 Annex H and IEC 60335-1 Annex R address the safety of MCU hardware and software used in appliances such as washing machines, dishwashers, dryers, refrigerators, freezers, and ovens. Building on the UL1998 foundation, additional requirements addressing the issues of software safety in programmable components for home appliances have now been added to the latest editions of the UL 60730/60335 standards. NETX DUO has satisfied those new requirements.
EAL4+ Common Criteria Certification
X-WARE IoT PLATFORM SC has achieved EAL4+ Common Criteria security certification. The Target of Evalution (TOE) covers THREADX, NETX DUO, NETX SECURE TLS, and NETX MQTT. This represents the most typical IoT protocols required by deeply embedded sensors, devices, edge routers, and gateways.
The IT Security Evaluation Facility used for the X-WARE IoT PLATFORM SC security certification is Brightsight BV and the Certification Authority is SERTIT.
FIPS 140-2 Validated
X-WARE IoT PLATFORM NETX™ Crypto libraries have achieved Federal Information Processing Standardization 140-2 (FIPS 140-2) Certification for software, which specifies requirements for cryptography modules. FIPS 140-2 requires all federal government agencies and departments that use cryptographic-based security to meet specific standards related to encryption strength and capabilities. These cryptographic-based security standards are also recognized in Canada and the European Union.
The Information Security evaluation lab used for X-WARE IoT PLATFORM NETX™ Crypto libraries was atsec and the certification authority is The National Institute of Standards and Technology (NIST).
