ISO/R 79:1968 Steel — Brinell hardness test [Withdrawn: replaced with ISO 6506-1 and ISO 6506-4] ISO/TR 79:2015 Reference materials – Examples of reference materials for qualitative properties; ISO/R 80:1968 Steel — Rockwell hardness test (B and C scales) [Withdrawn: replaced with ISO 6508]
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 ...
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]
The associated N reference numbers (second column) are specified in ISO 4063 (in the European Union published as EN ISO 4063). [1] Numbers in parentheses are obsolete and were removed from the current (1998) version of ISO 4063. The AWS reference codes of the American Welding Society are commonly used in North America. [2]

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 ...
IEC 61000-4-4 is the International Electrotechnical Commission's immunity standard based on electrical fast transient (EFT) / burst transients. This publication is part of the greater IEC 61000 group of standards which is covered under IEC TR 61000-4-1:2016. [1] The current third version of this standard (2012) replaces the second version (2004 ...
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 ...
