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. It does not indicate, except in a very broad way, the origin of the asgm or the suitability of the iron-carbon alloy for a particular service. Referenced Asmt purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

The size of graphite particles can range from very small Size 8 to relatively large Size 1. Link to Active This link will always route to the current Active version of the standard. Link to Active This link will always route to the current Active version of the standard. High magnification optical microscopy is required to reveal important details.

No other units of measurement are included in this standard. Graphite microstructure astm a are presented in the form of a microscopic image with a results astm a classifying the graphite.

Material testing you can trust since This method is only intended for the microstructure of graphite in iron castings. Graphite microstructure is useful in predicting the strength and impact resistance of an iron casting at specific locations. This test method is intended to be applicable for all iron-carbon alloys containing graphite particles, and may be applied to gray irons, malleable irons, compacted graphite irons, and the ductile nodular irons.
