ISO 14224 Petroleum, petrochemical and natural gas industries -- Collection and exchange of reliability and maintenance data for equipment is the International Organization for Standardization (ISO) standard relating to the collection of data for the management of the maintenance of equipment, including reliability data. It covers both ...
ISO 15769:2010 Hydrometry – Guidelines for the application of acoustic velocity meters using the Doppler and echo correlation methods ISO/IEC 15771:1998 Information technology – Telecommunications and information exchange between systems – Private Integrated Services Network – Specification, functional model and information flows ...
The series includes the ISO 14001 standard, which provides guidelines for the establishment or improvement of an EMS. The standard shares many common traits with its predecessor, ISO 9000, the international standard of quality management, [ 10 ] which served as a model for its internal structure, [ 8 ] and both can be implemented side by side.
ISO 13849 prescribes three methods to determine the MTTF D of a safety channel: use the manufacturer's failure data; use the methods prescribed in Annexes C and D of ISO 13849-1; use 10 years (i.e. assume the channel has low integrity) Mean Time to Failure (MTTF) is assumed constant during the useful life period of a component.
The failure mode may then be charted on a criticality matrix using severity code as one axis and probability level code as the other. For quantitative assessment, modal criticality number is calculated for each failure mode of each item, and item criticality number is calculated for each item. The criticality numbers are computed using the ...
The concept of 'dangerous failure' must be rigorously defined for the system in question, normally in the form of requirement constraints whose integrity is verified throughout system development. The actual targets required vary depending on the likelihood of a demand, the complexity of the device(s), and types of redundancy used.
SIA 2014 (1996), Swiss standard for engineers and architects, based on ISO 13567. ÖNORM A 6240-4 (2012), Austrian standard for digital documentation in technical drawings, based on ISO 13567. Samples of standardized layers: A-B374--E- (ISO13567: agent Architect, element Roof window in SfB, presentation graphic element);
The NASA standard and guidelines are built on ISO 12207, which is a software practice standard rather than a safety critical standard, hence the extensive nature of the documentation NASA has been obliged to add, compared to using a purpose designed standard such as IEC EN 61508. A certification process for systems developed in accord with the ...
