Standard Test Method for Folding Endurance of Paper and Plastics Film by the M.I.T. Tester
N ASTM D2176
Annotation
This test method describes the use of the M.I.T.-type folding apparatus for determining folding endurance of paper and plastics film. The M.I.T. tester can be adjusted for samples of any thickness; however, if the outer layers thicker than about 0.25 mm (0.01 in.) rupture during the first few folds, the test loses its significance. The procedure for the Schopper-type apparatus is given in Test Method D643
The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard
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
*A Summary of Changes section appears at the end of this standard
Автоматический перевод:
Стандартный метод испытаний для сопротивления излому пленки бумаги и пластмассы M.I.T. Тестер
Этот метод тестирования описывает использование аппарата сворачивания M.I.T.-типа для определения складной износостойкости фильма пластмасс и газеты. Тестер M.I.T. может быть приведен в соответствие с образцами любой толщины; однако, если внешние уровни, более толстые, чем приблизительно 0.25 мм (0.01 дюйма.) разрыв во время первых нескольких сгибов, тест теряет свое значение. Процедура для аппарата Schopper-типа дана в Методе тестирования D643
