Qualified Assessment in Compliance with Relevant Safety Standards
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 improved safety levels and helping to reduce residual risks. Standards IEC61508 and others can be integrated into existing quality management systems in a beneficial manner. The implementation of regulations and provisions within these standards provides a reliable basis for decision-making, particularly regarding safety structures, testing procedures, and tools. Development outputs can be validated at an early stage, while also reducing development time and costs. Furthermore, certification enhances the image and boosts the company's competitive position in the market.

SIL Functional Safety Certification is one of the key certifications for modern enterprises. In the modern industrial production that relies heavily on machinery, while improving production efficiency, the complexity of production processes and the precision of equipment can lead to uncontrollable variables and factors during the mechanized production process. For instance, equipment failures, instrument shorts, and system malfunctions can cause explosions, fires, and toxic gas leaks, posing severe threats to people's lives, property safety, and the environment, even resulting in catastrophic consequences.
How can we control this series of disasters and their consequences to minimize or keep them within an acceptable range?
Therefore, the SIL certification has emerged.
In fact, equipment failures occur at various stages of the product lifecycle, just with varying probabilities. SIL certification involves intervening from the outset of product design, implementing controllable management throughout the entire lifecycle of the product according to specific standards and mature norms, thereby reducing the likelihood of failures. This aims to control risks.

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:
A SIL1-rated actuator should have a failure probability controlled at ≥10^-6 to <10^-5 during continuous operation per hour.
SIL2 is from ≥10^-7 to <10^-6. SIL3 is from ≥10^-8 to <10^-7.
Of course, the requirements for a SIL3 rating are much higher than those for a SIL2 rating.
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 evaluates and confirms the Safety Integrity Level (SIL) or Performance Level (PL) of safety equipment. Functional safety certification primarily involves assessments of document management (FSM) for the development process of safety equipment, hardware reliability calculations and evaluations, software assessments, 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.
