SIL certification, as a safety certification project that has emerged in the fields of petrochemicals, machinery, rail transportation, automotive manufacturing, automation, etc. in recent years, is receiving increasing attention. So, many people are concerned about the main focus or issues that SIL certification focuses on?

SIL certification, also known as functional safety certification, focuses on the safety function of the product. Conducting SIL certification is to verify whether this safety function can be reliably and safely implemented. For example, for a lighting fixture, we are concerned about its lighting function, whether its illumination intensity can be reliable and safely meet our requirements.

So, what two aspects does SIL certification mainly examine?

Whether the product itself, as well as the hardware and software functions of the product to be certified, comply with the requirements of IEC61508 or more detailed industry functional safety standards for the product, such as hardware failure rate and failure mode;

Another focus of our investigation is the quality management system adopted during the development process, the qualifications and organizational structure of R&D personnel, and other systematic aspects to ensure that the methods and document systems followed throughout the entire R&D process of the product comply with relevant standard requirements. Through these two aspects of examination, we can say that a complete closed loop has been formed from the entire company to the R&D organization process and finally to the specific certification of products, which can ensure the reliable and safe implementation of product safety functions.
