BS EN 16991:2018 pdf download.Risk-based inspection framework
1 Scope
This European Standard specifies the Risk- Based Inspection Framework (RBIF) and gives guidelines for Risk- Based Inspection and Maintenance (RBIM) in hydrocarbon and chemical process industries,power generation and other industries where RBI is applicable.
Although RBIF encompasses both inspection and maintenance, this document focuses primarily on Risk- Based Inspection (RBI) and its applicability within the context of RBIM. The RBIF thereby supports optimization of operations and maintenance as well as asset integrity management.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1 risk
combination of the probability of occurrence of harm and the severity of that harm
Note 1 to entry: The probability of occurrence includes the exposure to a hazardous situation, the occurrence of a hazardous event, and the possibility to limit the harm.
Note 2 to entry: Other definitions, e.g. the one from ISO 31000 are recognized, but not used practically in the document.

3.2 risk management
coordinated activities to direct and control an organization with regard to risk
The approaches and methodologies used in RBIF can be compatible with the generic requirements resulting from basic ISO Standards such as EN ISO 9000-series[5], EN ISO 14000-series [6], ISO 55000 [Z] and in-particular, ISO 31000-series [8] (IEC/ISO 31010 [9], ISO/IEC Guide 51 [10], ISO Guide 73 [11]. Other standards with which RBIF can also be compatible are EN 13306 [12], ISO/DIS 45001, ISO 22301 [13], IEC 61508/ IEC 61511 [14] [15] and ISO/IEC 17020 [16].
5.2.2 Plant and process documentation
The development of a Risk- Based Inspection plan for different equipment items shall follow a well- defined, rigorous, and logical process to ensure that all pertinent information has been considered, and no critical factors are overlooked. The RBI process shall be clearly documented in a written procedure. This documented procedure shall be referenced, approved and controlled. The procedure shall define each step to be taken during the risk assessment process including the data journey and data quality needs of all data sets used for the risk assessment. The procedure shall explain in detail how PoF and CoF are established, and how this is used to determine the risk level and inspection plans. It is essential that all RBI assessments are clearly documented, with all factors contributing to the final risk assessment defined. The minimum documentation shall include:
一team members performing the assessment and their competence;
一previous assessment date;
一reassessment interval;
一list of factors used to determine risk (severity, probability of failure and exposure);
