introduction
Safety instrumented systems (SIS) were developed in the 1980s and.1990s and are widely used in oil and gas pipelines for their high reliability, safety and flexibility.
It has been widely used in the field of Taoism. Implementing SIS and responding correctly to hazardous process conditions can reduce the frequency of hazardous events.
Or mitigate the consequences of hazardous events, so SIS is an important measure to ensure the safety of oil and gas pipeline production. At present, relevant functions have been released internationally
Functional safety basic standard IEC 61508 (all parts) and functional safety application standard IEC 61511 (all parts) for the process industry, I
China has transformed it into GB/T 20438 (all parts) "Functional safety of electrical/electronic/programmable electronic safety-related systems" and
GB/T 21109 (all parts) "Functional safety of safety instrumented systems in the process industry".
The functional safety series standards of oil and gas pipeline SIS are GB/T 20438 (all parts) and GB/T 21109 (all parts) in oil and gas
Applications in the pipeline field. The purpose of formulating this series of standards is to standardize the technical requirements for activities in each life cycle stage of SIS in the field of oil and gas pipelines.
requirements, management requirements and application principles, promote the standardization of the application and management of SIS in the field of oil and gas pipelines, and ensure the safety of the oil and gas pipeline system
Reliable operation. At present, this series of standards has released GB/T 32202 "Specifications for Functional Safety Assessment of Oil and Gas Pipeline Safety Instrument Systems" and
GB/T 32203 "Specifications for Functional Safety Acceptance of Oil and Gas Pipeline Safety Instrument Systems".
The purpose of formulating this document is to guide and standardize the functional safety operation and maintenance activities of SIS in the field of oil and gas pipelines to ensure that it achieves and

3 Terms and definitions
The following terms and definitions apply to this document.
3.1
dangerousfailuredangerousfailure
A failure that prevents or prevents a given safety action from being performed.
Note 1.A failure can only be said to be "dangerous" for a given SIF.
Note 2.When fault margin is implemented, a dangerous failure can result in.
● SIF downgrade, in which case safety actions can be performed, but there will be a higher PFD or PFH, or
● SIF fails. In this case, safety actions cannot be performed at all or dangerous events have been induced.
Note 3.When failure margin is not implemented, all dangerous failures will cause SIF failure.

3.2
safetyfailuresafefailure
May trigger the failure of a given safety action.
Note 1.A failure is "safe" only for a given safety function.
Note 2.When fault margin is implemented, safe failure results in.
● Continue to operate when the safety function is available, but with a higher success rate or a lower possibility of dangerous events;
● Trigger safety function malfunction.
Note 3.When failure margin is not implemented, a safety failure will trigger the safety function regardless of process conditions. This is also called a malfunction.
Note 4.Malfunction is safe for a given safety function, but may be dangerous for other safety functions.
Note 5.Malfunction may adversely affect the production availability of the process.
