ГОСТ 23904-79

Brazing and soldering. Method for determination of materials welting with solders

Пайка. Метод определения смачивания материалов припоями

Status: Effective. The limitation of the effectiveness period has been lifted: Decree of the State Standard No. 4020 of 12.22.89

The standard applies to the method for determining wetting of materials by solders according to the following characteristics: wetting angle and spreading area; initial wetting speed and spreading time (for solders with Tm Ј 723 K). The standard is used to assess the compatibility of materials during soldering, the development of the soldering process and the optimization of its parameters, as well as in the development of new solders and fluxes.

Стандарт распространяется на метод определения смачивания материалов припоями по следующим характеристикам: краевому углу смачивания и площади растекания; начальной скорости смачивания и времени растекания (для припоев с Tпл Ј 723 К). Стандарт применяют для оценки совместимости материалов при пайке, разработке технологического процесса пайки и оптимизации его параметров, а также при разработке новых припоев и флюсов.
