In the analysis and measurement of residual stresses of materials, it has been noted that there are frequently differences in interpretation of the terms "macrostrain" and "microstrain." To assist communication among research personnel in this area, definitions for these two terms are suggested by the Fatigue Design and Evaluation Committee of SAE. Since "macrostress" is commonly computed from "macrostrain" in residual stress analysis, to be consistent, the definitions given are for "macrostrain" and "microstrain."

Blast cleaning may be defined as a mechanical pre-treatment process in which a suitable stream of solid particles is propelled with sufficient velocity against a work surface to cause a cleaning or abrading action when it comes in contact with the workpiece. Blast cleaning may be employed for a variety of purposes. It is a well-established method for removing sand from castings and burrs or scale from forgings, mill products, or heat treated parts; to promote machinability; and to minimize the possibility of interference in actual operation. In addition to this use, blast cleaning also produces a suitable surface for downstream industrial coatings. All these objectives are often accomplished in the one operation. As a general understanding, this document pertains to blast cleaning only. Any reference to shot peening or other processes is only to explain a context or concept related to blast cleaning.
Blast cleaning may be defined as a secondary manufacturing process in which a suitable stream of solid particles is propelled with sufficient velocity against a work surface to cause a cleaning or abrading action when it comes in contact with the workpiece. As indicated in the definition, blast cleaning may be employed for a variety of purposes. Ordinarily, it is considered as a method for removing sand from castings, burrs or scale from forgings, mill products, or heat treated parts; to promote machinability, and to minimize the possibility of interference in actual operation. In addition to this use, blast cleaning also produces an excellent surface for industrial coatings. All these objectives are often accomplished in the one operation.
