Qualification criteria for assessing the data developed by these methods can be found in ASTM product standards ast, may be described by purchaser-producer agreements.

Macroscopic methods include macroetch, fracture, step-down, and magnetic particle tests. When such steels are evaluated, the test report should describe the nature of the inclusions rated according to each inclusion category A, B, C, D. This practice, however, does not address the measurement of such parameters. Materials with very low inclusion contents may f45 more accurately rated by automatic image analysis, which permits more precise microscopic ratings.

Microscopic methods include five generally accepted systems of examination. In some cases, alloys other than steels may be rated using one or more of these methods; the methods will be described in terms of their use on steels.

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.

As stated in 1. Values in parentheses are conversions and are approximate. Only those inclusions present at zstm test surface can be detected. While the methods are primarily intended for rating inclusions, constituents such as carbides, nitrides, carbonitrides, borides, and intermetallic phases may be rated using some of the microscopic methods.

The degree of sampling must be adequate for the lot size and its specific characteristics. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. In these microscopic methods, inclusions are assigned to a category based on similarities in morphology, and not necessarily on their chemical identity.

Values in parentheses are conversions and are approximate. Metallographic techniques that allow simple differentiation between morphologically similar inclusions are briefly discussed.

The microscopic methods are not intended for assessing the content of exogenous inclusions those from entrapped slag or refractories. Although compositions are not identified, Microscopic methods place inclusions into one of several composition-related categories sulfides, oxides, and silicates—the last as a type of oxide.

In these microscopic methods, inclusions are assigned to a category based on similarities in morphology, and not necessarily on their chemical identity. 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. Also, by agreement, qualitative practices may be used where only the highest severity ratings for each inclusion type and thickness are defined or the number of fields containing these highest severity ratings are tabulated.

astmm Macroscopic methods include macroetch, fracture, step-down, and magnetic particle tests. By agreements between producer and purchaser, these test methods may be modified to count only certain inclusion types and thicknesses, or only those inclusions above a certain severity level, or both.
