Our services support the development of functional safety, ensuring the suitability and compliance of safety functions, systems, processes and components.
Functional safety is a part of overall safety that depends on the correct and timely functioning of safety functions – to ensure the safety of people and the environment. Functional safety is a means in which to lower the risks of industrial and societal processes to an acceptable level, when the risks cannot be completely mitigated due to, for example, stored energy (thermal, kinetic, pressure), process materials (chemicals), or because the process itself actively shapes or transports material.
Who needs functional safety
Functional safety and safety functions are typically needed, for example, in applications for the following industries:
- Process and energy industry
- Machinery and machine automation
- Railway and automotive industry
- Avionics, medical devices, electrical appliances etc.
In addition, functional safety aspects and standards often affect industries supplying components for use in the above industries.
Safety functions, generally, include electrical, electronic and programmable electronic parts, as well as actuators of other technologies that
- measure and detect hazardous conditions or deviations (sensors),
- decide on the demand for safety actuation (logic) and
- perform safety actuation, such as safe stopping (actuators).
Safety functions may also implement and require continuous correct operation, as part of electronic control systems, for example.
Independent Safety Assessments indicate the safety and compliance of safety functions, processes and components.
Why assess functional safety?
The assessment of functional safety is an activity that is required by many safety standards, with the intention of evaluating and ensuring the achieved level of safety. The required level of independence depends on the level of safety. However, conducted by an independent, accredited organization, our safety assessments fulfill the requirements of all relevant safety standards, for all levels of safety.
The assessments services are conducted in co-operation with our internationally acknowledged partner, SGS-TÜV Saar, with accreditation from DAkkS, Germany.
The accreditation covers most functional safety standards, including:
- IEC 61508
- IEC 61511
- IEC 62061
- IEC 61800-5-2
- ISO 13849
- ISO 26262
- EN 50126, EN 50128, EN 50129, EN 50159
SGS Fimko is also a European Union Notified Body for Machinery Directive, as well as for other relevant directives in the machinery domain, including the RED and EMC directives.
Our safety assessment services, cover the assessments of
- safety functions,
- processes and
The services are, thus, suitable for stakeholders and organizations ranging from system integrators and machine builders to component manufacturers.
Depending on the project, the design and development of safety functions, as well as hazard and risk analyses preceding the development, require the use of various techniques such as HAZOP, FTA, ETA, FMEA, FMEDA, Markov analysis etc. The analyses are needed, for example, in the identifying and quantifying of risks, as well as in determining the quantitative safety aspects specific to a safety function and to the achieved level of safety. Examples of typically required metrics include PFH/PFD, HFT, MTTFD, DC/DCavg and SFF.
The analysis services of SGS Fimko can be used both for calculating and confirming the achievement of the safety targets and for analyzing and optimizing designs during a project, in order to ensure the achievement of the targets. Depending on customer needs, we can conduct analyses based on provided design material and participate in customer workshops as external experts.
Training from SGS will ensure the competences of your personnel in critical development tasks.
Our training services are intended for providing and improving the understanding over key aspects, concepts and practices of functional safety and machinery safety, which are needed in tasks including the planning and management of functional safety. The trainings also facilitate demonstrating the personnel competencies, in compliance to standard requirements.
The trainings are conducted in co-operation with our internationally acknowledged partner, SGS-TÜV Saar, with use of the same proven training material throughout Europe. Our generic study modules include a written examination and are awarded with a personal certificate.
Automation and software safety (IEC 61508)
Machinery safety (ISO 13849, Machinery Directive)
Trainings and workshops may also be tailored for customer needs, for example, related to techniques and measures needed in the development work!
We also offer our functional safety customers other expert and advisory services, to facilitate decision making as well as for interpreting standard requirements. Examples of aspects with which we can help include
- alternative approaches and solutions in design and development, taking into consideration the intended use and maintenance of the system
- specification of diagnostic functions as part of safety system design – from the diagnosing of electronics to the diagnosing of safety functions
- optimization of designs, based on conducted analyses and previous experience on safety system development
- safety planning and software safety
