The significance of obtaining SIL certification for products
1. The impact of SIL certification on product accumulation:
We guarantee the accuracy of the product's specific functions.
(2) Enhances product acceptance and recognition within the industry.
(3) Certified products enjoy higher safety, enhancing their competitive edge.
(4) Customers typically perceive: Certified = Acknowledged = The.
2. The cumulative impact of SIL certification on the enterprise:
Enhance corporate safety experience and proficiency.
(3) The company's R&D process is more standardized and verifiable.
(4) Enhanced safety measures in place during occurrences of injury.
(5) Throughout the certification process, ensure the company maintains a high level of research and development.
If a project, system, or product achieves SIL certification, its quality and safety are also recognized, enhancing the company's market competitiveness while significantly bolstering customer confidence in the product. Therefore, it is necessary to undergo SIL certification for a product that significantly impacts life and property safety.

Safety Integrity Level, abbreviated as SIL, is differentiated by the probability of hazardous failure occurring per hour.
There are four SIL levels defined in the international IEC standards, with SIL 4 indicating a high level of integrity and SIL 1 representing a low level. For each safety integrity level, specific design specifications are established to reduce design errors.
The required safety level for the production process is assessed and determined by a specialized production technology company. Generally, for processes with high safety requirements, the required safety level is SIL 3.

8. Additional Information

SIL 2 and SIL 3 certifications are two different levels. According to international certification standards, the SIL 3 level is higher than the SIL 2 level. Specifically, it is characterized by:
A SIL1-rated actuator should have a failure probability controlled at ≥10^-6 to <10^-5 per hour of continuous operation.
SIL2 ranges from ≥10^-7 to <10^-6. SIL3 is from ≥10^-8 to <10^-7.
Of course, the product requirements for SIL3 level are much higher than those for SIL2.
Most products currently meet requirements with SIL 2 or SIL 3 certification levels.
SIL certification is a third-party assessment, verification, and certification process 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 the assessment 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, covering both product and system levels, with SIL4 being the most stringent.
