Standard Test Method for Determining Volume Fraction by Systematic Manual Point Count
 N E562

Annotation

This test method describes a systematic manual point counting procedure for statistically estimating the volume fraction of an identifiable constituent or phase from sections through the microstructure by means of a point grid.

The use of automatic image analysis to determine the volume fraction of constituents is described in Practice E1245.

The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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.

Метод стандартной пробы для определения объемной доли систематическим ручным графом пункта

Этот метод тестирования описывает систематическую ручную процедуру подсчета функциональных точек для того, чтобы статистически оценить часть объема идентифицируемой составляющей или фазы от разделов до микроструктуры посредством сетки точки.
