importance of SIL Functional Safety Certification

 Q & T INSTRUMENT CO.,LTD analyse the importance of SIL Functional Safety Certification 

Q &T Instrument Co., Ltd. has developed and produced electromagnetic flowmeters, vortex flowmeters, turbine flowmeters, metal tube flowmeters, and gas flowmeters for many years. At present, many products have obtained SIL certification.

For the sake of safety supervision, the company has a long-term and healthy development. It is the unshirkable responsibility and obligation of each individual to ensure the safe production of the chemical industry. Especially for each petrochemical enterprise, establishing a safety concept and doing a good job of accident prevention measures are the primary prerequisites for production work. How to minimize or limit the disasters and consequences of this series?

To this end, SIL certification came into being. In fact, equipment failures occur at various stages of the product life cycle, but with different probability of occurrence. SIL certification involves intervening at the beginning of product design, and manages the entire life cycle of the product according to certain standards and mature specifications, so that the possibility of failure is minimized. Thereby achieving the purpose of controlling risks.

Positive impact of SIL certification on flowmeter products:

1. It can guarantee the correctness of specific functions of the product;

2. It can improve the acceptance and recognition of products in the industry;

3. As the certified products have higher security, the competitiveness of the products is improved;

4, the customer usually thinks: certified = recognized = quality.

The positive impact of SIL certification on companies:

 1. Improve corporate safety experience and safety level;

 2. There is a clear competitive advantage for uncertified peers;

 3. The enterprise R&D process is more standardized and can be verified;

4. When the injury occurs, there is a higher security in the system;

5. In the entire certification process, ensure that the company's research and development level is maintained at a high level.

 If a project, a system or a product is certified by SIL, its product quality and safety are recognized and recognized. While enhancing the market competitiveness of the company, it also greatly enhances the customer's confidence in the product. Therefore, if a product has a greater impact on the safety of life and property, SIL certification is necessary.

 So, what is SIL certification?

SIL (Safety Integrity Level) is the safety integrity level. SIL certification is based on IEC 61508 (GB/T 20438), IEC 61511 (GB/T 21109), IEC 61513, IEC13849-1, IEC 62061, IEC 61800-5-2 and other standards, safety integrity level for safety equipment ( SIL) or performance level (PL) for a third party assessment, verification and certification. Functional safety certification mainly covers document management (FSM) assessment, hardware reliability calculation and evaluation, software evaluation, environmental testing, EMC electromagnetic compatibility testing, etc. for the security device development process.

Which level of SIL should be achieved by the safety-related system is obtained from the risk analysis, that is, by analyzing the four factors of the severity of the risk consequence, the time and frequency of the risk exposure, the probability of not avoiding the risk, and the probability of the undesired event. inferred. The higher the level, the lower the probability of dangerous failure.

In recent years, chemical safety accidents have occurred frequently, and everyone has "talked about change." In the chemical production operation, the safety requirements of the equipment should be highly valued.

Q & T Instrument has obtained SIL certification for various products, which reflects that the company's product quality has met the international safety standards, which indicates that the company's products have reached the high standards for the safety of instrument products during the petrochemical process.
