These services are aimed at manufacturers of components, sub-systems, 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 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 validated at an early stage, while also reducing development time and costs. Additionally, certification enhances the image and boosts the company's competitive position in the market.

What is the failure rate of SIL certification?
During the SIL certification process, a concept we often refer to is the failure rate of equipment. It is a core term in SIL certification. Essentially, without determining the failure rate, the SIL certification is incomplete and inadequate. So, what exactly is the concept of failure rate?
Firstly, to understand failure rate, we must grasp what is meant by 'failure'. According to GB/T 20438.4 and also the definition in IEC 61508, failure is "the termination of the ability of a functional unit to perform a required function, or the operation of the functional unit in a non-required manner." A more intuitive understanding would be: normally, y = f(x), but upon failure, it becomes y ≠ f(x), where f() represents the pre-set function, and y denotes our safety expectations. This also explains why 'function' is the same word for both 'function' and 'function' in English.
This statement might be too formal and not easily understood by the general public. So, speaking in layman's terms, it's like comparing it to a lighting system. If the lighting system doesn't light up or doesn't light up as per our set requirements, it's considered to be malfunctioning.
So said, you may all know that when a product doesn't function according to our specified requirements, we can say it's failed. Then, what's the probability of this failure? That's the failure rate.
After understanding what failure is, we can start categorizing types of failure. In the context of functional safety, failures can be divided into two main categories based on their generation cause: systematic failure and random hardware failure. Among them, random hardware failure is quantifiable. The calculation process of PFDavg is based on a probabilistic analysis of random hardware failure.
In the SIL certification, we aim to determine the product's failure rate by analyzing its theoretical model and utilizing empirical data from its market sales. This, combined with other components of the SIL certification, forms a comprehensive system to ensure the reliable and safe execution of safety functions.

The significance of obtaining SIL certification for products
1. SIL Certification's Impact on Product Integrity:
We guarantee the accuracy of the product's specific functions.
(2) Enhances the industry acceptance and recognition of the product;
(3) Certified products enjoy higher safety, enhancing their competitiveness.
(4) Customers typically believe: Certified = Recognized = The.
2. The cumulative impact of SIL certification on the enterprise:
Enhance corporate safety experience and proficiency.
(3) The company's R&D process is more standardized and verifiable.
(4) Higher security measures are in place during the occurrence of injuries.
Throughout the certification process, ensure the company maintains a high level of R&D capabilities.
If a project, system, or product achieves SIL certification, its product quality and safety are also recognized and approved. This not only enhances the company's market competitiveness but significantly boosts customer confidence in the product. Therefore, it is necessary to obtain SIL certification for a product that has a significant impact on life and property safety.

SIL certification, also known as Functional Safety Certification, focuses on the product's safety functions. Obtaining SIL certification is to verify if this safety function can be reliably and safely implemented.
For instance, with a lighting fixture, we're 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 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.
