Recently, the control valve series products produced by Xintai Valve Group Co., Ltd. have passed the review of the European Union's Italian Machinery Product Certification Center (ENTE CERTIFICAZIONE MACCHINE SRL, abbreviated as "ECM") and obtained the Safety Integrity Level (SIL) certification certificate issued by it. This means that the control valve series produced by Xintai Valve Group has been recognized by authoritative institutions and departments in terms of product design, system operation, and physical product quality, and has obtained the "passport" to go abroad and participate in international competition.
The issuance of this series of certificates fully demonstrates that Xintai Valve Group is constantly breaking through innovation boundaries in improving quality, optimizing efficiency, and enhancing services, while also continuously exploring and pursuing excellence in the field of safety.
SIL certification popular science Q&A
Q: What is SIL certification?
Answer: It is a third-party assessment that evaluates and confirms the Safety Integrity Level (SIL) or Performance Level (PL) of safety equipment.
SIL certification is based on IEC 61508（GB/T 20438）, IEC 61511(GB/T 21109), IEC 61513, IEC 13849-1, IEC 62061, IEC 61800-5-2 A third-party assessment, verification, and certification that evaluates and confirms the Safety Integrity Level (SIL) or Performance Level (PL) of safety equipment based on standards. Functional safety certification mainly involves document management (FSM) evaluation for the development process of safety equipment, hardware reliability calculation and evaluation, software evaluation, environmental testing, EMC electromagnetic compatibility testing, and other contents.
Q: What is the significance of SIL certification?
Answer: With the widespread recognition of industrial accidents and their impact on society, more and more companies are realizing the importance of safety. The process of SIL certification is to help enterprises fully utilize the best engineering practice experience and safety technology (IEC61508 and IEC61511) to avoid the recurrence of industrial accidents. Because these experiences and techniques are based on a large amount of practical experience and lessons learned.
The practical significance of SIL certification lies in:
1. Improve safety;
2. Prevent physical harm to production personnel and people outside the production area;
3. Avoid damaging the environment;
4. Avoid production losses;
5. Avoid legal liability.
Q: What are the contents of SIL certification?
Answer: According to the IEC 61508 standard (SIL certification), safety systems, sensing devices, and actuators are evaluated and certified. We will discuss the following topics to ensure a detailed and consistent evaluation of components (general or specific to 'safety circuits'):
1. Project document evaluation
2. Development and product design evaluation
3. Business process evaluation
4. Relevance of feedback (lessons learned) evaluation
5. Analysis and research on operational safety assessment
-Evaluate Failure Mode, Effects, and Diagnostic Analysis (FMEDA) analysis
-Calculation of Probability of Hazardous Failure (PFD) and Probability of Hazardous Failure per Hour (PFH)
6. Evaluation, Verification, and Validation Activities
