SIL certification, also known as Functional Safety Certification, focuses on the safety functions of a product. Obtaining SIL certification is to verify whether these safety functions can be reliably and safely implemented.
For instance, with a lighting fixture, we are concerned with its lighting function, whether its light intensity can reliably and safely meet our requirements.

The SIL assessment covers the following content:
1. System Evaluation
Risk Analysis, refer to risk classification chart (ASIL/SIL/PL)
Review of specifications and safety requirements
Concept and Design Analysis
– Verification and Confirmation
2. Software and Tool Evaluation
– 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 Applicability and Risk Analysis
Test and evaluate secure hardware and software during the development process
Conceptual Assessment (Initial Inspection)
Functional Safety Management (FSM)
- Security, reliability, and availability analysis
- Qualified Assessment Meeting Relevant Safety Standards
These services cater to manufacturers of automotive (including electric), elevator, power plant, machinery, and process industry components, sub-systems, and systems. They support the fulfillment of due diligence obligations, ensure the correct application of the standard, help enhance safety levels, and contribute to minimizing residual risks. The standards IEC61508 and the aforementioned others can be seamlessly integrated into existing quality management systems. The implementation of the regulations and provisions included in the standards provides a reliable basis for decision-making, particularly regarding safety structures, testing procedures, and tools. Development outputs can be verified at an early stage, thereby reducing development time and costs. Additionally, certification enhances the image and boosts the company's competitive profile in the market.

SIL Certification Costs 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.
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 document management (FSM) assessments for the development process of safety equipment, hardware reliability calculations and evaluations, software assessments, environmental testing, and EMC electromagnetic compatibility testing. SIL certification is divided into four levels: SIL1, SIL2, SIL3, and SIL4, covering both product and system levels, with SIL4 being the most stringent.
