It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. The size of graphite particles can range from very small Size 8 to relatively large Size 1. Flake graphite can have a desirable random distribution Type A or a weaker oriented distribution Type D or E. Graphite microstructure is useful in predicting the strength and impact resistance of an iron casting at specific locations. One section 1 x 1 x 0.

ASTM A247 - GRAPHITE MICROSTRUCTURE TESTING SERVICES

High magnification optical microscopy is required to reveal important details. Our laboratory also provides laboratory services for plastic testingmetal testingrubber testingoil testingpaint testingplating testingadhesive testingcircuit board testingand other testing.

Link to Active This link will always route to the current Active version of the standard. Good microstructural results require significant preparation to obtain a mirror finish with no scratches or edge rounding prior to etching.

One section 1 x 1 x 0. In an sstm specification for a specific material where graphite microstructure is an important consideration, this test method may be used as a reference to concisely define the graphite microstructure required. It does not indicate, except in a very broad way, the origin of the graphite or the suitability of the iron-carbon alloy for a particular service.

ASTM A - 10 Standard Test Method for Evaluating the Microstructure of Graphite in Iron Castings

Asym A provides images used to classify the form, distribution, and size of the graphite in an iron casting. Material testing you can trust since This method is only intended for the microstructure of graphite in iron castings.

Iron castings with graphite flakes gray iron are not as strong or impact resistant as those with asstm nodular graphite ductile iron. The excess carbon in iron castings separates into graphite of various forms.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of qstm standard. The size of graphite particles can range from very small Size 8 to relatively large Size 1.

It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. ASTM A is a method astmm evaluating the microstructure of graphite in iron castings. Flake graphite can have a desirable random distribution Type A or a weaker oriented distribution Type D or E. Advanced Sstm and Material Testing, Inc. Historical Version q247 - view previous versions of standard.

Other microstructural details must be evaluated using different methods. Graphite microstructure is useful in predicting the strength and impact resistance of an iron casting at specific locations. No other units of measurement are included in this standard.

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.

Graphite microstructure results are presented in the form of a microscopic image with a results table classifying the graphite.
