SIL certification service in accordance with the requirements of IEC 61508 Parts 1-7.
SIL certification process
The BYHON certification roadmap is based on a Functional Safety Assessment (FSA) process that consists in assessing the adequacy of the functional safety obtained from the analyzed equipment, compared to the clauses established by IEC 61508.
The certification scheme can be divided into three parallel phases:
Detailed review of hardware and software design, where auditors review the product design against functional safety requirements together with the manufacturer’s designers;
Revision of the development of the Functional Safety Management System, which aims to verify the presence and applicability of a management system for the fulfilment of functional safety requirements;
Quality constraint audit, which aims to verify the implementation of the quality requirements of IEC 61508 in the manufacturer’s quality management system.
The certification scheme, the Certification Agreement and more information about the certificates issued by BYHON are available on request by filling out our contact form, under the heading Request documentation and by specifying the type of document desired.Download the technical diagram Request documents
- Activity flow is top-down. All steps are shown chronologically (from top to bottom);
- The activities shown in parallel branches can be developed independently and simultaneously because the implementation of each phase is not closely related to the others;
- The documents listed to the left or right of each phase (blank) represent the input of a phase;
- The documents issued by BYHON along the workflow are highlighted in orange;
- Audits carried out at the client are highlighted in blue:
Detailed analysis and review of hardware and software, i.e. the review by product design auditors of functional safety requirements, working alongside the manufacturer’s designers. This audit may take several days depending on the complexity of the product.
Review of the development of the functional safety management system, which aims to verify the presence and applicability of a management system for the fulfilment of functional safety requirements.
The quality constraint audit, which aims to verify the implementation of the quality requirements of IEC 61508 in the manufacturer’s QS.
The SIL certificate will be issued following positive testing of the equipment at the customer’s premises based on the dedicated test procedure and the successful completion of all previous phases.
