Standard Practice for Extraction of Additives in Polyolefin Plastics
 N D7210

Annotation

This practice covers a variety of extraction techniques for antioxidant and slip additives used in polyolefins. Typically, the extracted additives are separated and quantified using a chromatographic technique such as the procedure explained in Test Method D6953. Chromatographic analysis of the extracts is not included in this practice.

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.

NOTE 1—There is no known ISO equivalent to this standard.

Общепринятая практика для извлечения добавок в полиолефиновых пластмассах

Эта практика покрывает множество методов извлечения для антиокислителя и смазок, используемых в полиолефинах. Как правило, извлеченные добавки отделены и определили количество использования хроматографического метода, такого как процедура, объясненная в Методе испытаний D6953. Хроматографический анализ извлечений не включен в эту практику.
