GOST 25284.4-82

ГОСТ 25284.4-82

Zinc alloys. Methods for the determination of lead

Сплавы цинковые. Методы определения свинца

Status: Not effective - Superseded

The standard contains instructions to avoid major defects of the machine as well as excessively overbalanced requirements for balancing, and can serve as a basis for research, for example, if it is necessary to more accurately determine the required quality of balancing. The standard is not a guide to the acceptance of rotors into operation.

Стандарт устанавливает атомно-абсорбционный, полярографический методы определения свинца при массовой доле его от 0,002 до 0,05 % и фотометрический метод определения свинца при массовой доле его от 0,004 до 0,05 %. Атомно-абсорбционный метод применяют при разногласии в оценке качества цинковых сплавов
