Safety Concepts
The first step in developing a safety critical product, which meets functional safety standards such as the IEC 61508, is to develop a high-level solution called the functional safety concept. The functional safety concept defines the key safety requirements, the high-level hardware and software architecture and the diagnostics approach.
Huld can take full responsibility of developing a safety concept for your system. We have extensive experience of standards such as IEC 61508, EN ISO 13849 and ISO 26262. The concept development will follow our standardized approach, which ensures that the end result will be a compliant safety concept that also meets your other requirements.
Development
Taking on a safety critical development project is challenging for the first time. The risk of overengineering or missing important aspects is significant. Huld has years of experience of developing mission and safety critical systems, making us a reliable partner for safety critical projects.
Huld can take full or partial responsibility of the project. Our services include:
- Safety management
- Safety analysis
- Full V&V responsibility
Safety Assessments
Huld conducts safety assessments in technology fields where functional safety plays a role: for example, automotive industry, nuclear industry, railway industry and medical industry. The purpose of Functional Safety Assessments is twofold: to ensure that all the activities and documentation for the particular Safety Lifecycle phase have been completed as per requirements (presenting a safety case), and to help prevent systematic failures from being introduced. Examples of relevant standards, against which functional safety assessments are conducted are ISO 26262, IEC 61508, EN 5012X.
Huld has been accredited by FINAS to be a type C Independent Safety Assessor (ISA) inspection body, accreditation number I051. Specifically, we can perform standard based safety assessments for Railway control, command and signalling subsystem (CCS) and Rolling Stock subsystems (RST). The standards in the scope of assessments include EN 50126, EN 50128, EN 50129, EN 50159 and IEC 61508. The SFS-EN ISO/IEC 17020:2012 standard is the accreditation requirement for inspection bodies.
We also do other assessments and gap analyses to support our clients in the following sectors:
-
- General industry where IEC61508 is applicable
- nuclear (regulatory guides and standards: YVL, IEC 61513 / 60880 / 62138 / 60987 / 60780),
- machinery (regulatory directives and standards: ISO 13849),
- medical (regulatory directives and standards: Medical Device Directive 93/42/EEC, Directive 80/181/EEC, ISO 14971, ISO 13485, IEC 62304, EN IEC 62366-1, IEC 60601-1, EN 1041),
- automotive (regulatory directives and standards: ISO 26262, Automotive SPICE)
- tractors and machinery for agriculture and forestry (regulatory directives and standards: ISO25119)
