Standard Test Methods for Apparent Density, Bulk Factor, and Pourability of Plastic Materials
 N D1895

Annotation

These test methods cover the measurement of apparent density, bulk factor, and where applicable, the pourability of plastic materials such as molding powders. Different procedures are given for application to the various forms of these materials that are commonly encountered, from fine powders and granules to large flakes and cut fibers.

The values stated in SI units are to be regarded as the standard. The values 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.

NOTE 1—Test Method A is equivalent to ISO Method R 60 as described in the appendix. Test Method C is identical with ISO Method R 61.

Методы стандартной пробы для очевидной плотности, коэффициента уплотнения и Pourability пластических материалов

Эти методы тестирования покрывают измерение очевидной плотности, объемного фактора, и где применимо, pourability пластмассовых материалов, таких как прессование порошков. Различные процедуры даны для приложения различным формам этих материалов, с которыми обычно встречаются от мелких порошков и гранул к большим слоям и волокнам сокращения.
