SIL Certification Fees and Timeline
The cost and timeline for SIL certification are directly related to the complexity of the product and the SIL level.
SIL Certification Standards
SIL Functional Safety Certification Standards: IEC 61508, IEC 61511, IEC 62061, ISO 26262, ISO 13849, etc.

The SIL level assessment covers the following content:
1. System Evaluation
Risk Analysis, refer to risk classification chart (ASIL/SIL/PL)
Review of Standard and Safety Requirements
- Concept and Design Analysis
– Verification and Confirmation
2. Software and Tool Assessment
- Testing of development tools and other communication protocols
- Structural Analysis
3. Hardware Assessment
Probability Analysis
Failure Analysis
4. SIL Certification
Parts and systems SIL Certification
Safety Process SIL Certification
- Granting of system, semiconductor, development tools, and process testing symbols
5. Additional Services
Risk Appropriateness and Risk Analysis
- Test and evaluate hardware and software for security during the development process
Conceptual Evaluation (Initial Inspection)
Functional Safety Management (FSM)
- Security, reliability, and availability analysis
- Compliant with relevant safety standards and qualified assessment
These services are aimed at manufacturers of parts, sub-systems, and systems for the automotive industry (including electric vehicles), elevators, power plants, machinery, and process sectors. They support the fulfillment of due diligence obligations and ensure the correct application of the standard, contributing to improved safety levels and helping to minimize residual risks. Standards such as IEC61508 and others can be integrated into existing quality management systems in a beneficial manner. The implementation of regulations and provisions in the standards provides a reliable basis for decision-making, particularly regarding safety structures, testing procedures, and tools. Development outputs can be validated at an early stage, while also reducing development time and costs. Furthermore, certification enhances the image and elevates the company's competitive position in the market.

What are the two main aspects that the SIL certification primarily examines?
The product itself, as well as the compliance of the hardware and software functionalities of the intended certified product, with the requirements of IEC61508 or more specific industry functional safety standards, such as hardware failure rates and failure modes.
Another focal point in our evaluation is the quality management system adopted during the development process, as well as the qualifications of the R&D staff and the organizational structure, ensuring that the methods used and document systems followed throughout the product development meet relevant standards.
Through these two aspects of examination, we can say that from the entire company to the R&D process and finally to the formation of specific certified products, a complete closed loop has been established, ensuring that the safety functions of the products can be reliably and safely implemented.
SIL certification is a third-party assessment, verification, and certification based on standards such as IEC 61508 (GB/T 20438), IEC 61511 (GB/T 21109), IEC 61513, IEC 13849-1, IEC 62061, and IEC 61800-5-2, which evaluate and confirm the Safety Integrity Level (SIL) or Performance Level (PL) of safety equipment. Functional safety certification primarily involves assessments of document management (FSM) for the development process of safety equipment, hardware reliability calculations and evaluations, software evaluations, environmental testing, and EMC electromagnetic compatibility testing. SIL certification is divided into four levels: SIL1, SIL2, SIL3, and SIL4, encompassing both product and system levels, with SIL4 being the most stringent.
