Characterization of waste - Leaching behaviour test - Influence of pH on leaching with initial acid/base addition
N CEN/TS 14429
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. The equilibrium condition as defined in the standard is established by addition of pre-determined amounts of acid or base to reach desired end 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 теста на поведение - Влияние pH фактора при выщелачивании с начальным кислотным/основным дополнением
Этот европейский стандарт указывает метод для определения влияния pH фактора на leachability неорганических составляющих от отходного материала. Условие равновесия, как определено в стандарте устанавливается добавлением предопределенных сумм кислоты или основы для достижения желаемых значений pH конца. Этот метод испытаний производит элюаты, которые впоследствии характеризуются физически и химически.
