Standard Test Method for Lead and Cadmium Extracted from Glazed Ceramic Surfaces
N C738
Annotation
This test method covers the precise determination of lead and cadmium extracted by acetic acid from glazed ceramic surfaces. The procedure of extraction may be expected to accelerate the release of lead from the glaze and to serve, therefore, as a severe test that is unlikely to be matched under the actual conditions of usage of such ceramic ware. This test method is specific for lead and cadmium.
The values stated in SI (metric) units are to be regarded as the standard. The values given in parentheses are for information only.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Автоматический перевод:
Стандартный метод испытаний для свинца и кадмия, извлеченного из глазурованных керамических поверхностей
Этот метод тестирования покрывает точное определение вывода и кадмия, извлеченного уксусной кислотой из глазурованных керамических поверхностей. Процедура экстракции, как могут ожидать, будет ускорять выпуск вывода от глазури и будет служить, поэтому, как серьезный тест, который вряд ли будет соответствующим при фактических условиях использования такого керамического изделия. Этот метод тестирования является определенным для вывода и кадмия.
