MOS Technology 6508 pin-out. There may be different strapping/bonding variants of this chip; the datasheet below lists pin 40 as clock phase two, but in the CBM900 computer, the 6508 controlling floppydisk has pin 40 as "Set Overflow" (SO). SO is a pin that is also offered on the 40-pin 6502, but omitted on all the 28-pin 650x variants (6503 ...
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). [1] 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 ...

The Vickers hardness test was developed in 1921 by Robert L. Smith and George E. Sandland at Vickers Ltd as an alternative to the Brinell method to measure the hardness of materials. [1] The Vickers test is often easier to use than other hardness tests since the required calculations are independent of the size of the indenter, and the indenter ...
ISO 22315:2014 Societal security – Mass evacuation – Guidelines for planning, is an international standard developed by ISO/TC 292 Security and resilience and published by the International Organization for Standardization in 2014. ISO 22315 gives various of recommendations on how to plan for possible mass evacuations, for example a city.
IEC 62279 provides a specific interpretation of IEC 61508 for railway applications. It is intended to cover the development of software for railway control and protection including communications, signaling and processing systems. EN 50128 and EN 50657 are equivalent CENELEC standards of IEC 62279. [6]
With the formation of ISO/IEC JTC 1 in 1987, ISO/TC 97 and IEC/TC 83 were combined to form ISO/IEC JTC 1/SC 7, Software Engineering. [2] In 2000, the subcommittee changed its title from Software Engineering to its current title, Software and Systems Engineering. [3] ISO/IEC JTC 1/SC 7 held its first plenary in Paris, France in 1987. [2]
