Introduction to SIL certification:

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.

Scope of SIL certified products:

1. Valves, actuators or actuators;

2. Various control instruments such as temperature, pressure, liquid level, etc;

3. Various electrical and electronic products for railway control and protection, such as SIS (Safety Instrumented System), ESD (Emergency Shutdown System), IPS (Instrument Protection System), BMS (Combustion Management System), F&G (Fire and Gas Protection System), HIPPS (High Voltage Pipeline Protection System), PSD (Process Shutdown System), etc.

4. Various safety transmitters, safety relays, etc;

5. Various types of safety light curtains, safety switches, etc;

6. Controller, including PLC, F&GESD, safety bus, etc;

7. Various security systems

8. Other electronic/electrical/programmable electronic products with safety requirements.
