ASTM E2142-08<\/h3>\n

Historical Standard: Standard Test Methods for Rating and Classifying Inclusions in Steel Using the Scanning Electron Microscope<\/h4>\n
\n

ASTM E2142<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This test method covers procedures to obtain particle size distribution, chemical classification, and Test Methods E 45 ratings of inclusions in steels using an automated scanning electron microscope (SEM) with X-ray analysis and automatic image analysis capabilities.<\/p>\n

1.2 There are three discrete methods described. Method 1 is the SEM analog of Test Method E 45, which uses image analysis and light microscopy to produce automated Test Methods E 45 ratings. Method 2 produces similar ratings based predominantly on sorting inclusions by chemistry into the traditional classes defined in Test Methods E 45. Method 3 is recommended when explicit detail is needed on particular inclusion types, not necessarily defined in Test Methods E 45, such as to verify the composition of inclusions in inclusion-engineered steel. Method 3 reports stereological parameters such as volume or number fraction, rather than Test Methods E 45 type ratings.<\/p>\n

1.3 This test method deals only with the recommended test methods and nothing in it should be construed as defining or establishing limits of acceptability for any grade of steel or other alloy where the method is appropriate.<\/p>\n

1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.<\/p>\n

1.5 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.<\/span><\/p>\n
