More E Based on the results of such tests, the other procedures may be utilized as applicable. Several methods may be employed for estimation of the depth of decarburization. The statistical accuracy of each varies with the amount of effort expended.

This procedure can be used to define the depth to a specific minimum hardness or the depth to a uniform hardness. Scope 1. The following basic procedures may be used: 1. These methods can be employed with any cross-sectional shape. The chemical analytical methods generally reveal a greater depth of decarburization than the microscopical methods but are limited to certain simple shapes and by availability of equipment. These techniques are generally reserved for research studies.

The microindentation hardness method is suitable for accurate measurements of hardened structures with relatively homogeneous microstructures. No other units of measurement are included in this standard. 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.
