Automotive Safety Integrity Level
:''This article is a discussion of ASIL as a means of classifying hazards, particularly to provide a context for comparison with other methods of classifying hazards, risk, quality or reliability. For a more thorough description of ASIL, methods of its assessment, and its roles within ISO 26262 processes, see ISO 26262 - Part 9: Automotive Safety Integrity Level.'' Automotive Safety Integrity Level (ASIL) is a risk classification scheme defined by the ISO 26262 - Functional Safety for Road Vehicles standard. This is an adaptation of the Safety Integrity Level (SIL) used in IEC 61508 for the automotive industry. This classification helps defining the safety requirements necessary to be in line with the ISO 26262 standard. The ASIL is established by performing a risk analysis of a potential hazard by looking at the Severity, Exposure and Controllability of the vehicle operating scenario. The safety goal for that hazard in turn carries the ASIL requirements. There are four ASILs identi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

IEC 62304
IEC 62304 – medical device software – software life cycle processes is an international standard published by the International Electrotechnical Commission (IEC). The standard specifies life cycle requirements for the development of medical software and software within medical devices. It has been adopted as national standards and therefore can be used as a benchmark to comply with regulatory requirements. Implications of IEC 62304 for software The IEC 62304 standard calls out certain cautions on using software, particularly SOUP (software of unknown pedigree or provenance). The standard spells out a risk-based decision model on when the use of SOUP is acceptable, and defines testing requirements for SOUP to support a rationale on why such software should be used. Contents General requirements * Quality management system * Risk management * Software safety classification Software development process * Software development planning * Software requirements analysis ...

ISO 13849
ISO 13849 is a safety standard which applies to parts of machinery control systems that are assigned to providing safety functions (called safety-related parts of a control system). The standard is one of a group of sector-specific functional safety standards that were created to tailor the generic system reliability approaches, e.g., IEC 61508, MIL-HDBK-217, MIL-HDBK-338, to the needs of a particular sector. ISO 13849 is simplified for use in the machinery sector. The standard has two parts: * ISO 13849-1, Part 1: General principles for design, provides safety requirements and guidance on the principles of design and integration of safety-related parts of control systems (hardware or software). * ISO 13849-2, Part 2: Validation, specifies the procedures to be followed for validating by analysis or tests, the safety functions of the system, the category achieved and the performance level achieved.

European Committee For Electrotechnical Standardization
CENELEC (french: Comité Européen de Normalisation Électrotechnique; en, European Committee for Electrotechnical Standardization) is responsible for European standardization in the area of electrical engineering. Together with ETSI (telecommunications) and CEN (other technical areas), it forms the European system for technical standardization. Standards harmonised by these agencies are regularly adopted in many countries outside Europe which follow European technical standards. Although CENELEC works closely with the European Union, it is not an EU institution. Nevertheless, its standards are "EN" EU (and EEA) standards, thanks to EU Regulation 1025/2012. CENELEC was founded in 1973. Before that two organizations were responsible for electrotechnical standardization: CENELCOM and CENEL. CENELEC is a non-profit organization under Belgian law, based in Brussels. The members are the national electrotechnical standardization bodies of most European countries. Relationships to c ...
