This standard specifies in detail the requirements, test methods, inspection rules, and marking, Encasement, transportation, storage, and order contents of ruthenium resistive pastes for potentiometers and variable resistors. The scope of application includes ruthenium resistive pastes for devices such as potentiometers and variable resistors. A series of related documents are cited in the document, including the general specification for potentiometers for electronic equipment, the general specification for film-fixed resistor networks for electronic equipment, etc. In this standard, the potentiometer nail resistive paste is defined as a paste composed of ruthenium dioxide powder, ruthenium salts, inorganic additives, and organic carriers that meets the printing characteristics.
