Standard Test Method for Determination of the Amount of Polypropylene (PP) in Polypropylene/LDPE Mixtures Using Infrared Spectrophotometer (FTIR)
 N D7399

Annotation

This test method uses an infrared approach for determining the presence of polypropylene (PP) physically mixed in with low density polyethylene – usually for recycling purposes.

NOTE 1—Quantitative determinations require several standard mixtures in the concentration range of interest and well defined baseline anchoring points.

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 2—There is no known ISO equivalent to this standard.

Стандартный Метод тестирования для Определения Суммы Полипропилена (PP) в Смесях Polypropylene/LDPE Используя Инфракрасный спектрофотометр (FTIR)

Этот метод тестирования использует инфракрасный подход для определения присутствия полипропилена (PP), физически смешанный в с низким полиэтиленом плотности – обычно для переработки целей.
