Characterization of waste - Leaching behaviour tests - Influence of pH on leaching with continuous pH-control
N EN 14997
Annotation
This European Standard specifies a method for the determination of the influence of pH on the leachability of inorganic constituents from a waste material. Approaching equilibrium as defined in this European Standard is established by continuous adjustment of the pH by addition of acid or base to reach desired pH values. This test method produces eluates, which are subsequently characterized physically and chemically.
This European Standard is a parameter specific test as specified in EN 12920. The application of this test method alone is not sufficient for the determination of the detailed leaching behaviour of a waste under specified conditions.

Характеристика отходов - Выщелачивание тестов на поведение - Влияние pH фактора при выщелачивании с непрерывным контролем pH фактора
Этот европейский стандарт указывает метод для определения влияния pH фактора на leachability неорганических составляющих от отходного материала. Приближающееся равновесие, как определено в этом европейском стандарте устанавливается непрерывной корректировкой pH фактора добавлением кислоты или основы для достижения желаемых значений pH. Этот метод испытаний производит элюаты, которые впоследствии характеризуются физически и химически.
