These services are aimed at manufacturers of components, subassemblies, and systems for the automotive industry (including electric vehicles), elevators, power plants, machinery, and process sectors. They support the fulfillment of due diligence obligations and ensure the correct application of the standard, contributing to enhanced safety levels and helping to minimize residual risks. Standards such as IEC61508 and others can be integrated into existing quality management systems in a beneficial manner. The implementation of regulations and provisions within the standards provides a reliable foundation for decision-making, particularly regarding safety structures, testing procedures, and tools. Development outputs can be verified at an early stage, while also reducing development time and costs. Additionally, certification enhances the image and elevates the company's competitive position in the market.

As the public awareness of industrial accidents and their impact on society grows, more and more companies are realizing the importance of safety.
In modern process industry production, due to complex processes and numerous equipment, any failure can have severe consequences for employees, the public, equipment, or the environment.
The SIL certification process involves helping businesses fully leverage their proven engineering practices and safety technologies (IEC61508 and IEC61511) to prevent industrial accidents from recurring. This is because these experiences and technologies are based on extensive practical experience and lessons learned.
With the issuance of the IEC 61508 and IEC 61511 series standards, a systematic functional safety assessment and testing process effectively addresses this issue.

SIL certification, also known as Functional Safety Certification, focuses on the safety functions of the 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.
SIL certification is a third-party evaluation, 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, assessing and confirming 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 evaluations, environmental testing, and EMC electromagnetic compatibility testing. SIL certification is divided into four levels: SIL1, SIL2, SIL3, and SIL4, encompassing both product and system levels, with SIL4 being the most stringent.
